I just got a BlackView BV9000 Pro in the mail. I stuck my SIM card in it and its being read, I can see my contacts and phone number from it. But its not able to log into my network for whatever reason.
I took it to the ATT store to have them verify I had the correct APN and they made a new SIM for me, but it still didn't work for them either.
I've also noticed the boot up screen shows on boot, then waits for me to unlock it, then in splashes again before waiting me to unlock it a second time before it goes to the home-screen. This gives me the idea that the phone might be DOA or the ROM might be corrupted.
I am in Orlando, FL and just got my Blackview BV9000 in the mail and have the EXACT same problem. I too am with ATT and tried switching SIM cards and all the correct APN info....any luck solving this? Thanks.

I called AT&T again and spoke with someone more willing to help. It appears we are the earliest of adopters here. Their system just doesn't recognize the phone because they've never heard of it.
Engineering said they would be researching the phone and adding the model to the network.
Give them another call and get yourself in the queue to get it added.
10-4, I will call them today....any idea how long this will take? Thanks, at least I'm not in this alone, lol!
Please tell me you guys didn't buy that? If the system doesn't have the device then it reg as an unknown device and will still work.
They told me it would take under 2 weeks, that was a couple days ago.
@zelendel I'm not sure what you are getting at. I'm only going by what they told me.
Something about the system defaults to 2g for unknown devices but they have decommissioned all of their 2g network, so I have nothing until they add it to their system .

What I'm getting at is that is bs. I worked for att and know just how this works. And that line is complete crap.
After looking at the specs for that device I'm betting you will still have issues due to the bands needed to get 3g or lte on att. As long as the device supports the bands it will connect automatically to the bands needed. This is how their byod works.
And after looking at the specs. I'm right. It is missing most of the bands needed.

That's not good... I ordered 3 of them....
Bands were checked....still no connect.
Blackview's tech told me to check the bands too...(which I did before purchase), and according to ATT, the phone has the correct bands to connect....ATT uses the following: GSM 850 & GSM 1900....Black view BV9000 Pro has GSM 850, 900, 1800, and 1900. ATT uses the following LTE band frequencies: 700, 1700, 1900, 2100, and 2300........Blackview BV9000 Pro has LTE 700, 850, 1700, 1800, 1900, 2100, and 2600. These are the identical band frequencies my Samsung 8+ has.......thoughts anyone? Thanks!

I really thought it would match up enough to at least connect to the network.
I had the G1 back in the day and made do with 2g on the att network
Specs DO match up...
Yeah, ATT urged me to reach out to Blackview, (which I have)....because according to the phone specs, it should connect "no doubt"....the numbers don't lie, the tech said. They DO match up.....

In your experience zelendel, do you think it would connect to T-mobile (or another) since it appears to have both of their bands listed?

If it has all of their bands then yes. But if it is missing even one then you might run into issues.
This is a lesson that many have forgotten with the availability of global devices. China uses different bands then the states. This means most times devices sold from China will not always work in the states.
I make a habit to make sure all the bands are listed. This way there is never an issue.
I have a BV9000 Pro here and can see the supported Bands (not only frequencies) in the MTK Engeneer Mode ("call" *#9646633# and go to Telephony > Band Mode > SIM1". Maybe this helps you.
BV9000 Pro supports:
GSM Mode: EGSM900, DCS1800, PCS1900, GSM850
UMTS Mode: WCDMA-IMT-2000, WCDMA-GSM-900
LTE Mode: Band 1,3,7,8,20 (only for SIM1 deeper on the tray, not for upper SIM2)
I have the same problem i already sent my problem to blackview, i tried everything *#*#4636#*#* but for some reason my bv9000 pro when i tried to select radio band just dont have any answer... I also tried several apn but still my 4g keep witouth working. If for some reason i fix my problem i let you know...

There is no fixing it. If it doesn't have the bands for your carrier then you are sol. Remember you get what you pay for. When you go cheap you have to make sacrifices.
HEY!!! Two points:
1) When you are checking frequencies of phone and carrier (to see if they match) you need to know the "B" number. For example, there are at least 4 "B" numbers for 700MHz that I am aware of. So if your phone spec says 700MHz, is it B12 700MHz or B17 700MHz or B28 700MHz? Right frequency alone means nothing. Having said that, the BV9000 has ALL the right "B" numbers to fully support both 3G and 4G LTE on AT&T, T-Mobile, and many resellers. All it is missing is 600MHz that T-Mobile is rolling out. But I don't think T-mobile even offers a handset for that yet. So it's as "compatible" as anything you could purchase directly from AT&T or T-Mobile, at the moment.
2) I have owned many Chinese phones. Without exception, they all need to be tweaked a bit when you first unpack them, or they will NOT connect to ANY carrier, even with a properly activated SIM. The process is roughly..... A) Go into setup menus to enable data on SIM 1 (or SIM 2) B) Go into setup to enable ROAMING data for SIM1 (or SIM 2). You must say to allow roaming because when the phone is new, technically ALL networks are "ROAMING". You will get a warning message about roaming data usage being expensive, acknowledge it. C) Power the phone down completely powered off. D) Turn the phone on and wait five minutes. E) Sometimes you have to do step C and D 2 or 3 times before you will get a connection.
NOTE: Before you successfully enable data and roaming data and reboot, you will not be able to make phone calls or send/receive text messages. You will likely get a "no service" message or a signal strength indicator of NO bars. Also, for some few handsets, you MIGHT have to manually input the APN settings for whatever network you are trying to use, even if you have a properly activated SIM card for that network. But even if the SIM card is recognized and APN info is loaded automatically....you still need to enable data and roaming data before you can make phone calls, or try to use the Internet.
Even customer service reps for the various carriers are not aware that Chinese phones need to have data and roaming data enabled before any good, activated SIM will work. So if AT&T told somebody to contact Blackview (for example) that would make sense. AT&T really (honestly) probably thinks that the handset is broken. While the handset COULD be broken, it's probably working fine, after you tell it that 'yes, I want to roam".

Is this a way to get a LTE network in US ?
I heard that the phone needs a Global ROM Network Firmware? is this something that you guys heard? if it does, how and where do I get this firmware?
My Brother in law said this is what Dealer in indonesia do when receiving phones from china, they alter it and download Global Rom network before they re-sale the phone to public.

Hello
I have recently bought the HTC Rezound and have noticed that when i go to which from LTE on/off (*#*#4636#*#* in dialer, then phone information) there is a option for "Global Mode" and ones for "WCDMA Only" and "GSM Only"
I have seen websites saying that they can unlock the phone and it will work with any network?
But my question is, is this phone possibly a global phone?/GSM and WCDMA support?
UPDATE: Okay just got the htc rezound today and put in my T-Mobile UK sim card, and switched to "WCDMA only" mode, and without unlocking it picked up signal (i live in uk) it also says t-mobile in notifications, i checked and called the defice and the call was received.
UPDATE 2: Okay so I am able to receive and make calls, HAVE DATA (Go to thread at bottom of this post to find out how to get data to work ) and can receive texts BUT AM NOT ABLE TO MAKE THEM!
UPDATE 3 (24/01/2012): I can confirm you can receive signal and data with Ice Cream Sandwich (ICS) and Gingerbread (GB) ROM's but the SMS not send problem is the same for all ROM's (until we get S-OFF and hopefully the Developers Port/Create a GSM or Hybrid GSM/CDMA radio )
UPDATE 4 (26/01/2012): I would like to say thank you to Droid Life, for the acknowledgment of my thread ,and hopefully with this spreading the word more we can get the Radio/Fix (after we get S-OFF) to the SMS/Texting not sending problem, and the HTC Rezound would be (like it should of been ) a fully World Phone . Check out the Page: http://www.droid-life.com/2012/01/26/htc-rezound-has-secret-global-radios-after-all/
UPDATE 5 (31/01/2012): Received a screenshot from kirasama1014 which shows the HTC Rezound was able to receive signal and DATA in on a Taiwan network!!!, a thanks to kirasama1014 for the screenshot
Screenshot: https://docs.google.com/leaf?id=0Bx...NmY4MC00ZmFmLWE2OWItODkwZGUwNzZhODEy&hl=en_US
UPDATE 6 (03/02/2012): The HTC Rezound has been confirmed to work and receive data on T-Mobile USA, same SMS issue for everyone (Hopefully fix soon ).
UPDATE 7 (06/02/2012): It has been suggested that the SMS issue could be down to framework being incompatible, and it has been said that DEVs may be working on this for us, so in advance THANK YOU!!! and hopefully we are closer to having the SMS issue out of the way!
UPDATE 8 (08/02/2012): BEST METHOD FOR DATA:
1. Go into Setting>>>Wireless and Networks>>>Wi-Fi Settings then pree the menu button (Physical button) and choose advanced.
2. When in advanced set 'Wi-Fi sleep policy' to 'After 15 min'.
3. Make sure you have entered correctly your APN settings for Mobile DATA/Internet AND SELECTED IT!.
4. Connect to a Wi-Fi Network (Preferably your home network).
5. Now turn off the phone screen/lock the phone (Do not turn it on anymore till after the last step)
6. Now go out of range of the Wi-Fi Network you are connected to, and when you think your out of range start timing 15 minutes (I usually wait 17 Minutes just to be sure) and remember to not turn on the phone screen until the time is up, and do not go back into range of the Wi-Fi Network you where connected to until the time is up!.
7. After time is up you should HOPEFULLY have DATA!!!!!
(I ALSO SUGGEST THAT YOU SET THE NETWORK TYPE TO WCDMA Preferred (Which is what I use, but this option will only work if your network/carrier supports it, and I'm guessing most do, and why not if you have tried everything else ))
This method worked 3 out of 3 times I tested for me, and I also suggest you do this when going out somewhere. HOPE THIS HELPS GUYS!!!
UPDATE 9 (20/02/2012): Still looking for fix to the SMS/Texting problem ,have just tried another suggestion of entering a PDU format of carriers SMSC number but still no luck (Apparently this works for AT&T so if you have them as your carrier you may be in luck).
UPDATE 10 (08/03/2012): There is now a Bounty thread in the HTC Rezound General section, for the Developer/s who solve the SMS/texting problem, so please if you also would like this problem fixed go to the thread and add a stated amount of at least $5 in either the thread as a reply, or Private message me with the amount and I will add your name to the list
UPDATE 11 (19/03/2012): People have tried and confirmed that the latest RUU is able to send SMS flawlessly, and also there is no annoying 'SIM Unknown' message on lockscreen!!! YAY!!!
UPDATE 12 (22/03/2012): I cannot test as I am away at the current time, but I think the ROM which allows SMS and doesn't have the Lockscreen 'SIM is from unknown source' message is the Sense 4.0 Alpha 2 by newtoroot, can anyone test?
FINAL UPDATE 13 (20/05/2012): Well Done Joelz, the only person/developer to show a real interest in the GSM capabilities of the HTC Rezound, and he has now succeeded in fixing the problem of SMS not sending!!! Well Done mate and please everyone show your appreciation
This will be the final update, so good luck to all GSM users/travelers owning the HTC Rezound and Thank You All! , HAPPY NEW YEAR ALSO!!!
Heres Where You Can Find The Fix (Once again well done Joelz): http://forum.xda-developers.com/showthread.php?p=26199933
AND FOR PEOPLE WHO HAVE CUSTOM ROMS, YOU MAY HAVE TO THE 'TWEAKS' MENU IN SETTINGS AND THEN 'Phone Information' FOR THE *#*#4636#*#* MENU TO APPEAR)
Below is now the old pieces of writing from when I first got the HTC Rezound and was writing about the problems it (No Longer ) has
----------------------------------------------------------------------------------------------------------------------------------------------------------
MY OTHER THREAD:
Okay first off I can CONFIRM THE REZOUND IS A GLOBAL PHONE (lets just get that out of the way).
EVIDENCE
Okay so I purchased my HTC Rezound form an American eBayer and he shipped it to me just after Christmas (i live in the UK), i was already under the impression that the Rezound was a global phone but just before it arrived everyone was saying that it doesn't have the GSM or WCDMA networks which made me sad
But when it arrived i thought i would try what i thought would work, sooooo i place the sim card in the phone and powered it up. After setting it up i went to the phones dialer and dialed: *#*#4636#*#* and then went to phone information and changed the network type. I was shocked to find that there was many options including 'GSM only' and 'WCDMA only' . So i switched the phone to WCDMA only and the phone picked up signal and showed T-Mobile in the notification bar .
(I got my data by adding the T-Mobile APN and then going to wi-fi settings>>advanced and changed the time till wifi switches to mobile network to 15 mins (then waited 15 mins after screen lock))
OTHER POSSIBLE METHOD FOR DATA! 23/01/12 :
Enter APN settings (make sure this is correct for the Internet/mobile data of your SIM Cards carrier) Turn WiFi on and then turn it off.
Then make sure Mobile Network is turned ON, and make sure you are receiving signal.
Now take off the battery cover and leave off until you see that you have no signal (This is when there is a cross on the signal bars)
Now put the battery cover back on and wait for a moment and hopefully you should have DATA!!!

Problems (That i think can be fixed)
1.Lockscreen message that says "This SIM card is from an unknown source".
TEMP FIX (Until Reboot): If the ROM you are using has the tweaks menu (MikROM) then you can go to Miscellaneous Options>>>Choose Lockscreen Style and select 'Android Lockscreen', Then Restart or Hot Restart and change the option back to 'HTC Sense Lockscreen'. THIS WILL REMOVE THE 'This SIM card is from an unknown source' message, but this process must be done every time your battery dies or you turn off the phone.
(still better than the ugly message every time you turn on the phone screen).

Holly crap, I had just heard this as rumors when it was in production. But yes it definitely looks like its a global phone.
I never bothered to check. I just did and you are right it has global options as well as gsm. Hmm I'm going to call Verizon to get my unlock code
Sent from my ADR6425LVW using xda premium
This would be a pleasant surprise, but the FCC filings did not include the GSM bands from what I can see.
It doesn't have the gsm radio in it from what I've seen on ifixit
sent from my newly unlocked Rezound
I Had My SIM Card Replaced Mid November And The Verizon Rep. Asked Me If I Went Out Of The Country; That To Me Sounds Like It Is A Global Phone.
This would be amazingly pleasant. I was just looking to buy a global phone.
I may have some pleasing news to share later on as i am going over families tonight and my cousin siad he would bring his phone with his UK sim card (T-Mobile) (he lives in the UK) and hopefully when i purchase an unlock code i can confirm whether this is a global/GSM supported phone or not
Fingers crossed!
I believe there was a thread on this when this phone first came out. They said this phone is set up exactly like the Thunderbolt and it is not a global phone. They said you could possibly use it on a CDMA network in Europe, but not on a GSM network. Someone just needs to ask VZW.

The truth about the htc rezound
I posted this on the rezound developers page but wanted the rest of the Rezound owners to know the truth about their phone. "THE TRUTH WILL SET YOU FREE".
I spoke to HTC directly about this very thing. I discovered the other radios with the PHONE INFO APP (WCDMA, GSM (only), GLOBAL MODE, GSM+LTE/EVDO auto, GLOBAL LTE MODE) along with the standard CDMA+LTE/EVDO auto and CDMA auto (PRL). Also so confirmed by when I pulled of the back battery cover and exposed several of the gold plated radio antenna's. The HTC tech support manager said to me that HTC Rezound is a world phone despite Verizon's tech support claims that it will only work on Verizon's LTE/CDMA network. HTC's tech said that this phone will work any where in the world. All you need is the SIM card and the SIM Card unlock codes that Verizon should provide to you if you have been a customer long enough. She further said that you can ONLY GET THE CODES FROM VERIZON'S TECH SUPPORT, NOT FROM VERIZON CUSTOMER SERVICE.
She said with the SIM Card and Codes the phone will operate any where in the world where their is a cell phone signal. Depending on the Network it's hit or miss on having data service, but you will be able to receive and make call plus send and receive text no matter with or without data service.
VERIZON Doesn't advertise the Rezound as a world phone and will tell you it's not, they don't want us to know it's a world phone
Bottom line with all of the other great things this phone does: direct to tv plug, great camera, hd video,(Dr. Dre) Beats audio, speed, smoothness, ect...
This is the best phone on the best phone on the Market by far.
VERIZON Doesn't advertise the Rezound as a world phone and will tell you it's not, they don't want us to know it's a world phone. Why I wonder, I think we all know why.
My history with Android is the Original Droid, Thunderbolt, and now the Rezound.

It should prompt you for it as soon as you turn on the phone with anything besides a Verizon SIM in it. I'll update tonight. I'll let you know if Verizon gives me a hard time about the unlock code. Thanks.
OK, so update. I went ahead and inserted a "3" sim into my Rezound. The phone boots and says that "This SIM is from an Unknown Source."
It does not prompt for a SIM unlock code and does not pick up any service.
I am not surprised.

Hello Guys,
I am so desperate and frustrated, hope you can help me!
I dropped my phone from 2 stairways height.
It was working so i didnt care, but when I came home I noticed that I had no reception!
So as I have bought the phone from Germany Amazon.com and using it in Turkey, I had no warranty (even if it said I have!!) I decided to open my SGS2 (I9100) and see if anything was loose. I lifted the pins that touched the middle housing and now I have reception for phone calls all the time thanks God!
But I have no 3G at all, what happens is that is some times shows G in the status bar but never with a + sign near it. I saw + sign only once or twice in the last couple of months.
I called my operator which is Turkcell and they said that my contract is on 3G so no chance on that side. The wierd think is that my phone works with no other SIM card than mine which is 5 years old!
Can anybody help in order to solve my problem? Is there a diagnoses tool that will help me test my SGS2 in order to find the errors?
Thanks for reading guys, I'd really appreciate some help.
Hmm I'd check my APN settings first, make sure they didn't randomly change for some reason. If that failed, I'd factory reset. If that failed I'd flash a new firmware+kernel+modem, and check my APN settings again.
If that failed I'd open it up again, disconenct and clean the antenna wire, reattach and hope for the best.
If that failed I'd suss out what is the most appropriate looking part/area of parts to replace, then replace it with either that specific part, or a pre-assembled part with the surrounding parts attached.
If that didn't work I'd list it on ebay as clearly stating the phone is damaged, outlining the problem and sell it "for parts only". Lots of people pay good money for damaged smartphones. Just make sure any sensitive data/pictures etc have been securely removed before selling it.
The problem with reception was fixed with lifting the pins that touched the middle housing but, stand by :
I think I never had 3G since I bought that phone from Germany.
I feel so stupid!
I read through more and more and I found that article:
androidforums.com/samsung-galaxy-s/258859-how-enable-850mhz-3g-network-frequency-your-samsung-i9000-galaxy-s.html
It mentioned about the modem frequencies so gave it a try.
dialed the number * # * # 1 9 7 3 2 8 6 4 0 # * # * as stated and bingo!
My modem doesnt list GSM 2100 which is the deault frequency for 3G in Turkey!
But the article doesnt mention how I can ADD GSM 2100 from the menu that dialing that number took me.
Any help with this is appreciated!
First, that article is for am i9000, which is the S1. But that's largely irrelevant because the service menu code still works.
Second, this phone doesn't get GSM 2100. Never has. It gets WCDMA/UMTS 2100. GSM is for voice and 2g, WCDMA is for 3g/HSPA. Looks like you went to the wrong option. (GSM, instead of WCDMA, like the article said.)
Third, you CAN'T add frequencies, on that menu or otherwise.
Thanks.
So why is that my phone connects with only Edge?
Can this be a hardware problem where everything else works?
Maybe these setting are wrong? Or maybe it has a SIM lock? but it works with Turkcell
Is there any manual so that I can these settings_

You said above you don't think you ever had 3g. Maybe your carrier uses 3g frequencies this phone simply doesn't receive.
For example, this phone well never get a 3g signal on T-mobile USA's network, because the phone doesn't receive 1700 UMTS/WCDMA. This is one of two required bands on AWS... Which is the band T-mobile USA uses for 3g and "4g". If your carrier uses AWS for 3g, it won't work on their network either.

No this is not possible. Turkcell is using 2100 Hz.
I have bought 3 phones from amazon.de site. The other 2 phones are working.
I have to get my settings set properly, to make sure its a faulty product, so that I can return it.
There are menu options like HSPA revision, GCF, bank selection, service domain, acquisiton order etc..
Where can I find what they have to be?

In that case, just go back to that service menu, debug screen - phone control - network control - band selection. Make sure this is selected to automatic. You can make sure all available bands for this phone are selected on in combi bands. If they're all selected on, then it sounds like it could be a hardware issue.
EDIT to add: OR it could be a modem issue. Maybe try flashing different modems?

I thought it was funny. He's loving the phone so far! Does anyone else have this dev edition?
Semi-related: We're on AT&T and have a shared data plan, and tethering is allowed by AT&T. Is there a hidden hack he can do to enable it? The phone will not allow it right now, and AT&T can't help him out because they don't 'have' the phone.
Yep, same here - got mine at Build.
But I'm on Sprint so I can't just move my sim over.
It may live out it's life on just WiFi.
it's a slick phone, that'd be very sad to hear.
I was at build also. I spent 2 hours with AT&T techs yesterday, and could not successfully get internet sharing working.
I'm getting a feeling that the firmware on the build phone isnt final, and we may have to wait for a firmware udpate.
To get internet sharing to at least load without saying call at&t or that it wasn't supported, I had to configure a new apn named "broadband". None of the pre-configured apn settings work for tethering.
But once I did that, I can connect to the hotspot, but the phone does not want to route any data through it. So devices connect, but cannot connect to the internet. Its quite odd, and the AT&T techs were stumped.
It probably lacked AT&T's specific module for tethering. You may need to 'upgrade' to AT&T official ROM.
Broadband APN is tied to your account. When you are eligible to use tethering, it get enabled. So, I'd double check the account setting on AT&T side.
On Android phones, I know tethering is secretly routed through a hidden broadband APN built inside ROM's SQLite config database while normal phone connection is routed throuh ptr APN (for LTE). With a rooted Android phone, you can change the hidden APN back to ptr and get around the tethering account requirement.

All LTE phones require a SIM card. But for Sprint and Verizon, currently they run phone calls and SMS on CMDA side and data on LTE side. So the SIM card for Sprint and Verizon are in fact data only. Verizon is actively testing Voice over LTE and promised to deploy them in near future. When that happens, CDMA will no longer be used. Everything will be over LTE. But that is long way to go.
On the other hand, this phone actually works with T-mobile 3/4 G as well (it is penta-band unlike the AT&T retail version). So, you can as well get a prepaid account for T-mobile. There is no Sprint WP8 phone come out anytime soon.
Just out of curiosity, when you start the phone up, do you have a carrier splash screen?

I've got a Lumia 900 on the account, and tethering is enabled, and that works fine. if I'm not using the broadband APN, it actually tells me I have to call at&t or go to the AT&T web site (giving me the exact url) to add the service to my account. So I'm not sure why it actually doesn't work on the 920.
Hopefully someone will figure it out at some point.

No, it is a dev phone not specifically designed for AT&T. You can't even get cell data connection before you make a manual selection of APN for AT&T.

That is because your Lumia 900 is an AT&T branded phone. This one is not. And AT&T has special requirement/software for handling tethering. If I would make a guess, AT&T uses Broadband APN to test if you qualify for tethering but use ptr (for LTE) for actual data transmission once verification passed. You actually have to have a USB broadband stick on your account to use Broadband APN for data transferring.

I heard rumors that the 920s at the BUILD 2012 conference were taken from the Canadian shipment, so I was curious.

I suspect that is true because when I first powered it up, it defaults to Canada region settings and time zones.
Anyway, I played with different manual APN settings. It seems that the phone firmware is hardcoded not to allow tether for both PTA APN (for LTE) and Phone APN (for HSPA+). Any other APN will be ok but my phone with my current account settings (unlimited data) won't let me use either AT&T 3G APN (wap.cingular) or anything else for internet connection. So the end result is the same.

That could explain why Roger model is pentaband :victory:.
For anyone wondering, my dad figured out the tethering. Oddly enough, he installed the Spanish keyboard and Internet sharing turned on. Weirdest thing ever but he claims it worked. You can change it back to English after. He found this on some forum post he said. Regardless, problem solved!

Thank you! Adding a keyboard (in my case, I added Spanish(Mexico) causes the phone to download an OTA update. After the update process finishes, the tethering works without changing APN. So, now I can freely tether my tablet to it on my unlimited data plan!

sadly, this didn't work for me on AT&T. I tried both Spanish updates, but still cannot tether.
There is a lot of attention regarding this Dev Kit due to the fact that is PentaBand.
Hopefully Microsoft and/or Nokia USA will make this model available, maybe over the Microsoft Stores?

Did your phone go through a few reboots to apply the update? Which APN is your phone configured to use? This Dev phone comes with 3 preconfigured APN for AT&T:
* AT&T LTE1
* AT&T LTE2
* AT&T 3G
Only AT&T LTE2 will fully function for this phone.

I seriously doubt it. They need carrier's approval to sell anyphone with carrier's LTE support. Take a look at Google's new Nexus 4 dev phone, it contains no LTE what so ever. The last gen Galaxy Nexus with LTE is a Verizon branded phone and can only be purchased via Verizon.
Installing either version of the spanish keyboard did not allow tethering. My APN settings just say "AT&T" . The difference is my phone was from AT&T so it probably has some other lock on tethering. More details on how this was done would be helpful unless it just isn't possible for me. I was already prepared for not having tethering with my unlimited plan anymore with my lumia 920 (came from android where custom roms allowed for tethering) so here's to hoping it is possible at some point.
This thread is about the special dev version ms gave out at BUILD2012 conference. Not the AT&T retail version.

I recently signed up for a LTE plan, and the frequency of my provider is supported by the phone. I signed up for the plan, and did a factory reset from the about phone menu to make sure everything was reset.
The phone starts up, and it automatically picks up the APN information from - somewhere, not sure where to be honest. To make sure it detects the LTE network, I changed Highest connection speed to 4G in Settings > Cellular
However, no matter where I am in the country, the signal indicator shows full bars and either H or H+, it doesn't show LTE or 4G - so I thought it could be that the APN information isn't correct.
On my phone under Settings > System there is an option called "access point"; this has a the two default APNs from my provider; but I can't seem to edit them; only switch between them. Long press on either one shows only "activate" as the menu option.
Under Settings > Cellular there is "add internet apn", but this is blank.
All this leads to the following questions:
1. How can I edit or check the settings of the default access points under "access point".
2. Filling in the information under "add internet apn" doesn't seem to change anything.
3. Is H+ the same as LTE/4G or something else?
4. Do I need an updated SIM? The company promoted LTE with the iPhone 5 and under the FAQs one of the answers is to get an updated SIM if LTE doesn't work.
All of this is moot as the Lumia 920 does not support the LTE frequency that Zain uses, which is 1800 MHz. The highest speed you will see is H+, an evolution of 3G.
There are two versions of the 920. The non AT&T version supports 1800.

So it does... I was looking on the Wiki site and it didn't show it, but it does here: http://www.gsmarena.com/nokia_lumia_920-4967.php. Can you do a quick check in the ##3282 menu and see what bands are available for LTE on your particular device?
The problem was with the SIM. I went to the provider and I asked them to provide me a LTE SIM for the Lumia 920. Conversation went like this:
Me: "Hi, I have already activated LTE on my line, but I need a new micro sim"
Them: "Okay no problem but the iPhone 5 supports the nano SIM"
Me: "Yes, I know but I need a micro SIM because my phone is the Lumia"
Them: "Sorry we only support LTE on the iPhone 5".
Went to another branch
Me: "Hi, I need to replace my iPhone 5 SIM."
Them: "Certainly sir, the first replacement is free. What is the number?"
Then I went to a shop and got the nano to micro converter and now I have LTE on my Lumia. It shows up as "L" instead of "H+".
The iPhone 5 still manages to pull in a faster connection though, by a margin of 4 MB/s (using speed test at the same location, against the same server).

Great! Glad you were able to get it sorted. The SIM was going to be my next suggestion.
(US ATT and T-Mobile)
I have this phone, but only by way of ATT telling me my non-VoLTE 4G LTE phone would not work after ATT shuts down 3G.
I move over to T-mobile recently. All works ok. I then activate VoLTE on the Mi. All works ok.
But I had to call a T-mobile rep regarding my iPhone, in that conversation I asked if VoLTE was even needed, and he tells me no, that T-mobile will still do voice data w/o VoLTE enabled.
So, VoLTE is a feature of LTE and implemented on 4G/5G, and really has nothing to do with 3G being shut down.
There's so many sites stating you "need" VoLTE to keep making voice calls after 3G is gone. This is not true.
"As 3G is switched off, you need VoLTE or HD Voice support to make calls on 4G networks."

As I understand it you need 3G for voice.
You may be able to use internet service but without VoLTE, no phone service.
If the device is not white listed it likely will not be able to have phone service as your link states.
I have straight talk with AT&T sim, I was using my Black Shark 3 pro which has volte and all of a sudden Friday at midnight, no data or phone service. At that time my bs3pro has been having heating issues, so i moved everything over to my redmagic 6 which has volte. I noticed my sim was locked in apn, totally different apn info than my bs3pro, so i called support, since everytime I tried to make call it blocked calls and sent me to support. The CS person did something on their end, had me restart phone, then service was back to normal and been fine since.
If your service provider only provides 4G infrastructure like mine... then you need VoLTE otherwise no phone calls. They are new and never had any 3G and below infrastructure. I tried making calls .... it doesn't.
My service provider annoyingly doesn't provision volte for my volte capable handphone (this makes my eyes swivel) but does provide an app to support phone calls without volte.. but it chews up battery
@roger_rex
But T-mobile (US) runs 4G and 5G, but # of towers with 5G not as plentiful as 4G. I connect 4G LTE most of the time, voice & data works just fine. T-mobile rep told me it will work w/ or w/o VoLTE enabled on phone. The APN used is the "fast" APN one.
A 5G connection does not negate any benefits from using VoLTE.
Was on phone again today with a T-mobile "tech team supervisor" for a service issue (they accidentally turned off one of my SIM cards). I then asked about VoLTE, he tells me it's no longer needed on T-mobile 4G or 5G LTE, but using VoLTE will still work. He seemed to suggest VoLTE not needed at all on 5G because the speed of the wireless can carry both voice and data fast enough. He also hinted their 4G can do the same.
If you have a fast pipe then you really don't need a side channel for the voice.
But duly noted, everything technical that I have read about on VoLTE, using that feature gives better voice call on any LTE that supports VoLTE. The supervisor also mentioned that "VoLTE" will basically go away at some point.
Pretty sure on 4G LTE you need either VoLTE capability or a 3G connection for voice calls.
Redirect Notice
4G VoLTE will likely be here for a long time as 5G is distance/obstacle limited, the former is very hard to overcome due to the wavelength's physical properties.
@blackhawk
I am not disputing how online info says it's required, I am just copying what T-mobile has told me.
T-mobile store rep tells me VoLTE is not really needed, then their online support supervisor tells me the same thing. So it is for sure confusing.
Call a T-mobile support # and ask.
Why would a 3G/4G-LTE phone have an option to turn off VoLTE?

I never paid much attention to this and still have questions but it's back burnered for when I run across it. From what I'm reading the T-mobile reps sound like they don't understand it either.
Even if they don't understand it... the only thing that matters immediately is if it will work. Hopefully that intel is correct!
Really until AT&T implements the change I won't be 100% sure. However pretty sure I'm ok as the devices don't use the 3G band and in hidden user settings VoLTE is toggled on. The only indication other than the 4G that VoLTE is active.
Probably HD too, but no indicator or setting other than very good call quality.
To make matters even more confusing AT&T changed the format and models listed drastically 2 weeks ago from their December whitelist. So small wonder reps might be confused too. Makes you wonder if it was deliberately self serving, an oversight or ongoing system modifications?
So, I have not been paying close enough attention to cellular these days. The cell companies have amassed large sets of licensed bands, probably near 200+ bands between 2G/3G/4G LTE and 5G NR.
Interestingly enough, 5G is not LTE at all. I suspect operators call their crud "5G LTE" to signify they support 5G-NSA or 5G-NR (or both), and, the older 4G LTE.
Some airlines are worried about two cell C bands (n77 and n79) that back up onto aircraft radio altimeter that run 4200-4400Mhz.
VoLTE has a long history, but it seems 5G-NR does not even use VoLTE (because VoLTE is a LTE feature, and 5G is not LTE). Can a 4G/5G phone still use VoLTE? Sure, if the firmware is implemented to use it. Likely will use it if the device connects 4G LTE, but perhaps will not when connected to 5G-NR. It's not clear to me if a device will use both 4G LTE and 5G-NR at the same time, but I suspect not. I mean, you could technically connect a device on 5G-NR for data, and then use VoLTE on 4G LTE for facilitating voice calls.

My understanding on this is that voice was using some 3G or below service. My provider was purely 4G and above - so unless my phone was provisioned by the cell company - no voice calls. I tried & it didn't work. I changed to an older device that they did support via VoLTE and calls worked. I can download an App from the cell company that allows my pixel 2XL to work on their system.
I can only guess T-mobile has 3G and below network infrastructure still. My provider is brand new and never built any 3G stuff and have no intention of rolling out obsolete stuff. VoLTE is annoying in that the provider gets to pick and choose which cellphones they allow (to use a standard protocol)
This may not be 100% - I've been kind of forced into a crash course on this myself over the last few days

Pixel 2's all have ability for VoLTE.
A cell operator should not be blocking any phone from using VoLTE.
When you call your provider what do they tell you when you tell them your Pixel 2 has VoLTE for 4GLTE but your Pixel won't make calls on their network?
I can tell you for sure, the operators play games with their support of hardware.
My iphone XS was connecting to ATT with a "5G" icon from time to time, so why does T-mobile say 5G is a "no"? I moved the XS to T-mobile and the phone won't ever connect to 5G, and the APN settings appear to be blocked.
Tutorials | T-Mobile Support
Update: I find many sites that say the Xr and Xs do not support 5G, so now I scratch my head, my Xs would sometimes show "5G" icon for cell wireless, when it was on ATT network. Apparently AT&T supports Xs and 5G, hence the Xs does have 5G capable radio.

I can tell you for sure, the operators play games with their support of hardware.
My iphone XS was connecting to ATT with a "5G" icon from time to time, so why does T-mobile say 5G is a "no"? I moved the XS to T-mobile and the phone won't ever connect to 5G, and the APN settings appear to be blocked.

I think they go at least partially by number of a given model in use. My guess is it's not a painless procedure for them to configure their system for a given model.
AT&T first listed their Note 10+ variant but not the unlocked variant, a month later it was added as well. It may be a work in progress... it seems sort of helter skelter, oh my gawd get it done, whatever it takes... kind of deal
You know they are catching Berlin air raid volume flack
Before buying Mi 11 Lite 5G I went into a T-mobile store (not an affiliate). I asked if the Mi 11 Lite 5G will work on T-mobile and the rep told me all phones work on T-mobile as long as they are not locked to another carrier, and, the T-mobile freq bands ("channels") are covered by the phone.
Unless LTE or 5G-NR/5G-NSA is improperly implemented on the device, then I don't see why all phones should not work. They should all work.
Think about hotspot. The carrier can control is the device can use that service, or at least can with some devices, but why bother, who cares how the data on the data plan gets chewed up. Go over the plan and get charged. Thus far I have not seen unlimited hotspot data, T-mobile only allows 40G on their Magenta Max plan.
Good thing is, Mi 11 Lite 5G phone (model M2101K9G) works a-ok on T-Mobile USA. I did have to manually set the APN to the "fast" one, and had to use dial code for VoLTE, 4GLTE and 5G works.
Straight talk now keeps shutting off my service every 3 days, last night again, so 3 times now. Call and back working. But seems like they only care about giving me some crappy free phone and seems like they outsource. The redmagic 6 is not on AT&T list, if any more issues I will switch to T Mobile, T Mobile recognized my phone by imei and said it is fully compatible. I Noticed on my Redmagic 6, sim 1 is only 14 digits but sim 2 is 15, so I moved sim card, might be issue, but doubt it.
@Rotwiler I see you posted about the IMEI digit thing in another post/forum. *#06# should reveal a 15 digit IMEI. If it shows only 14 then the phone is hiding one digit. Put sim card in sim slot that has the 15 digit IMEI.
What does *#*#4636#*#* get you? Do some gooling around for activating VoLTE on RedMagic 6
Phone lists for carriers are mostly for support reasons. If the phone has all the cell bands the operator uses, then it should be good to go. If the phone only has some of the cell bands used, then the phone may work ok in one area, but not good in another, all depends on how the operator runs the bands in different areas. The cell operator does not want the support headache for a phone that only has partial bands, "hey ATT, my phone not working in Timbuck-too", etc.
The RM6 appears to have most of the ATT 4GLTE bands (all the major ones), so it should work a-ok on ATT (US). 5G should also work. It appears the RM6 had a firmware update about 26d ago. Make sure the firmware is updated to latest.
Are your APN settings correct?

I am using AT&T through Straight Talk. I did move sim card to slot 2 to see if issue was due to sim one showing only 14 digits. Phone is fully updated. Odd thing is I cannot change the APN since this new Volte, there is red check mark and everything is grayed out. I have always been able to modify APN until now. My sim card is really old, used to be full size and over the years cut it down for new phones, is probably 8+ years old, had it since Android phones came out, but has always worked great.

APN settings are grayed out when the phone is locked to carrier. Can you at least see what the APN settings are? If the phone is owned outright by you then tell the Straight Talk folks you want the phone unlocked.
As for old sim card, then just go get a new one from the store for a few $, and then move your number to the new sim card via online.
Phone is Redmagic 6 global version, never was locked.
