Ive had many "not registered" errors when trying to place a calls over WiFi and called in for support to TMo many times. The third week and the fourth or fifth "PDA" service guy went all out and then gave up and turned me over to "Loyalty". Its like getting switched to the inquisition. THEY told me, 'bad news' Vibrant can't make calls over WiFi. SO I confessed it only worked 50% of the time.
When I agreed to take the phone, TMo said it would support UMA. In the mean time I think they decided they would not support UMA. I can call TMo phone mail no problem and the phone rings and then disconnects. It will make a call from "voice" but shows the not registered error when I dial a number. It has to be TMo router settings. They offered to send me a 3G Curve which they said would support UMA telephony, but they had no other phones - oh yah maybe the "Shaddow" was available but even they wouldn't go so far. I'm SOOOO sick of RIM, really, really sick. So I rejected that. So now I'm making calls and receiving calls over WiFi, but not reliably and with no support.
I'm fairly certain this is the tip of the big iceberg. My Vibrant was very early pre-purchase, so it might not have had all the TMo down mods. Never the less, it seems crazy that I would pay them to use my own DSL/WiFi as I seem to be doing with my HTC Incredible/Verizon phone. It works great, but of course I pay.
TMo gave me some questionable information regarding using Vonage, which I found does is not suposed to work with the Vibrant. They also said no Android phone will work with TMo hot spots, which I am inclined to accept. It appears all the carriers will do anything to keep a branded hand set off of free WiFi telephony. So I'm trying Google Voice. It registers, but I have so far not recieved a call to my new Gvoice phone number.
Do I need to root the phone? Are there apps that will help? Does any one out there think the 2.2 upgrade with the TMo holy water has a ghost of a chance of making WiFi phone calls without a TMo charge? My Incredible/Verizon still tethers on PDA-net and I think that is not charged. But I'm not clear on that either.
I just pre-bought a Tab through Cell Phone Hut. I will see if a device free of TMo tweeks will route telephony over WiFi. All I really need is a cheep pre-paid SIMS card for OTA. It's nuts thinking to pay 3G or 4G OTA data rates when the same data is free over WiFi. There will be many Android apps to do all your data I/O when you are in range.
cheers all... thx for any light on this!
Umm what? You're able to make calls on wifi 50% Of the time. You can make Google voice calls over wifi? You were told the vibrant would have uma? ?? Maybe I'm misunderstanding you but....
Google voice is NOT a voip service so i think you're misjudging its use.
Vibrant was never said to have wifi calling, just like every other android.
An app called kineto was recently announced that does wifi calling but its not uma. it doesn't hand off to cell network. Its announced to be available for the new mytouch n moto defy.
Also, tmo uma will no longer give you 'free calling'. It takes from your minutes so its only real advantage is to extend coverage.

The Vibrant hasn't been confirmed to ever get Wifi calling but it was demo'ed on a Vibrant running 2.2. The feature could possibly be added to the vibrant once it receives the 2.2 update.
This is strange. We've had our vibrants about a week. When I'm home I have the Wifi turned on. The signal bars drop to zero. I have just assumed that my voice calls were going over Wifi to our DSL modem over the Internet.
Note: We happen to have a T-Mo wireless router from back in the days when we were using it with our Blackberries to keep the minutes down. Subsequently T-Mo switched us to an unlimited plan, but we still use this router for one hard-wired home line.

Signal bars dropping to zero is just a visual indicator; doesn't necessarily mean there is zero signal, just not enough signal to flip the visual indicator. This happens to me quite a lot - I have no signal, but someone calls me and the call quality is fine.
In any case - basic logical fallacy - correlation does not necessarily imply correlation. Although it would be super nice to make calls over wifi!
<------ Tmo Retail Rep
There is no Android phone that supports UMA at the moment. The only Android that will have UMA that has been announced so far is the myTouch HD. Not sure why someone would tell you the Vibrant has the feature.
Not only that, 0 bars doesn't mean no service. The circle with a slash means no service

Where was it ever said that the Vibrant would have UMA? Its one thing if a rep was mistaken but no slick, ad, spec sheet, or anything else that I recall ever implied that UMA was going to be available. I came from a Blackberry to the Vibrant so I felt I was aware that UMA was not available.
UMA in Android NOT
Apparently Android has no UMA support, but a lot of people want it:
Check out Issue 6242 - Google's board for android code / issues.
I am thinking about moving to vibrant and tmobile. the only thing that is stopping me is the lack of uma support on the vibrant. Does anyone know whether this is capability will be added with the 2.2 update??
Have you guys not tried any of the new leaked froyo roms? They all have wifi calling and it works, although its not uma and doesn't hand off it works great. This is actually a Godsend for I have had Tmobile for 7 years and I get no service in my house, finally a solution. I'm not sure this will be released in the upcoming froyo update or it was just pulled from the Mytouch4g and they made it work for our phones.
Hi,
I got a new lumia 800 about a week ago and I've noticed it makes interference sounds (the same noise one would hear coming from a radio speaker while a mobile getting a call or msg near by) while speaking on the phone or even when just browsing or playing with it. It seems strange to me as my old phone never made these sounds. Has anyone experienced this on their lumia?
i've got the same issue. I was surprised, how is this possible on 2nd millenium phones. I just got used to it, because i don't believe, there is any solution.

I know, it seem strange for a "new" phone like this to do so when my last few phones which are years and years old now never had that problem. I talked to Nokia technical support on their site about it and after I reset the phone and it still did it they told me to take it back to the shop and try to get it replaced or send it to them for a repair as it seems like a hardware issue. Only I don't think my retail store would give me a replacement even tho it's only a week old and I always fear sending phones for repairs after few bad experiences in the past. So I guess I'll have to get used to it just like You say
You are using only GSM aren't you? Try to use 3G, it shouldn't do it. I'm using GSM, because i have EDGE unlimited internet data plan and there is no 3G in our town, otherwise i would use 3G as well.

Hi,
I have the network set for automatic but I have noticed that where I live it often swaps between 3g and Edge as the signal here isn't the best. Do You think that could be the cause of the static sounds? The only thing is that none of my old phones, neither my family ones ever done that. And their phones change between 3G and Edge here also.
My better half caught me looking at the Xperia z ultra. She surprised me with a c6833 model. It should be here the end of the week.
We are over-the-road truck drivers running the lower 48 states. Our phones are on Verizon. I do a lot of calling to book loads and Internet searches. I do some streaming of music and video.
Can I move my Verizon sim card to the new phone? I know I will not get LTE service from Verizon. What I can't find is the simplest questions . Will the phone even make calls, text or MMS? Can I get other Internet service that is non-LTE? Can I connect to my wife's hotspot to get LTE Internet? I may have to get a T-Mobile account, but if there are work arounds I would rather not.
I know around here these are basic questions but if you are going to learn to count to 10, you have to learn how to count to 3 first.

Yes , u can get internet service with non-LTE. You will be gettin Wifi-Connection when you connect to Wife's Hotspot. Data Transfer would be faster cause as you said your Wife has LTE.

C6833 - LTE for T-Mobile
C6806 - LTE for T-Mobile and AT&T
C6802 - 3G for all networks
So even thought you have the single band LTE device, you will still get 3G coverage and data/ downloads. You will also be able to connect to your wife's hotspot and get LTE that way. But wont be as fast as LTE through a provider as its piggybacking.
I would suggest getting a T-Mobile account. (if they have coverage for where you will be)

The problem with the "where you are" plan is we drive 1000+ miles per day. We have no idea where that would be. So as long as I can make the call part work and there is a work around for the interest, I'm happy. The super big screen when viewing load details will far out weigh some of the small draw backs like no LTE or having to connect to a hotspot. We drive for me hours in some states where we don't even have basic phone service.

yeah I know what you mean. I travel a lot of part of my job, and often I have zero reception too. You'll be happy with your version of the Ultra. wifi hotspots will be the best choice and other than that 3G will suffice.. :good: or nothing...

While I'm not a cheap SOB, okay I am, if it gets to bad I'll pay up for an account at T-Mobile, but why if I don't really have to?
Thanks everyone. While I can find info down to the glue it's stuck together with I couldn't find the basics of can I call home on it. I'll bet I can find somewhere if ET can phone home with it.
So, I just purchased a MediaPad Honor X1 (3G Only model 7D-501u). My carrier is T-Mobile and I am located in a refarmed/modernized area (Phoenix, AZ). Unfortunately, my MediaPad is not functioning on T-Mobile. I get a 3G signal (and even H+), but cannot get any internet data. I have tried all the APNs (epc.tmobile.com, fast.t-mobile.com, and all recommended combinations in between). But still, no data! I have mobile data enabled, tried both network mode=3G and 3G preferred, tried updating stock firmware to Android 4.4, then back again (couldn't deal with the large font size), still nothing. Voice calls are very inconsistent, most of the time failing before a connection is even made. I tried 3 different SIM chips, and even a brand new one that T-Mobile provided for me, no go.... I have a call into tech support and waiting for some assistance (not that they can help me at this point).
Phone/internet works on 2G/Edge when hardset in the Network Mode, but that is just too slow to feasibly use. Thought it might be a radio problem, but I've tried two AT&T SIMs and Internet 3G/H+ fires right on up with no problems. So good news if you are on AT&T and wan't a MediaPad X1. I got around 4-5 Mbps download..Plenty fast. But I really don't want to switch to AT&T.
Don't think I have any options at this point. I'm trying to communicate with the store in China I purchased it from, but you can imagine how that is going
I love this device. Really! I would definitely keep this as a full-time daily device if I can get this working. The build quality is fantastic (except for this problem of course), screen is great, battery is great, and it's really compact for a 7 inch screen. But.....it doesn't work on the Uncarrier!!
I'll see if the T-Mobile Engineers have any suggestions, and if that doesn't have any positive results, which I'm sure it won't, I will have to try and either get a refund or sell it online! (Any AT&T customers want a good deal on a beautiful 7 inch phablet?)
Sorry for the length of this. Anyone have any experience with this issue, or maybe can anyone out there in Phoenix area validate if their's is working on T-Mobile?
Thanks.
P.S. I have a Huawei Ascend Mate 2....Sweeeeeet device. Love it! But unfortunately it seemed to get smaller the longer I had it. It was time to upgrade to a bigger screen. Anyone else have that problem with your devices shrinking on you, lol?

You on T-Mobile? I received my MediaPad 3 days ago, never been able to get data yet. I'm assuming at this point I never will and am close to moving on. What has your experience been so far overall with the MediaPad?

Yeah I'm on tmobile, but don't have a media pad. I was searching to see if anyone mentioned any data issues on tmobile on xda and found your post. The issue might just be tmobile, not the hardware because I found a lot of people saying the same thing on tmobile' s Facebook page. I also had the icon show up, but no data.

Good to know. I have a ticket in with a T-Mobile Engineer. Should hear back within the next day or so. I will keep you informed of what I am told. My wife has my old Verizon Samsung Note 2 on T-Mobile and it's been working fine. It would also be using the 3G 1900 Mhz frequency. So you would think if the Note 2 Internet is working right now on T-Mobile, my 3G Mediapad X1 should work too. But it doesn't
MediaPad X1 no Internet with T-Mobile wifi hotspot
So on top of not being able to get internet with my T-Mobile SIM insert into my Mediapad, I'm also not able to get Internet when I have my Mate 2 setup as a wifi hotspot and the Mediapad using a wifi connection to the hotspot. Unable to browse to any sites. The Mediapad does get internet while connected via wifi to home router. How strange is that! Again, AT&T SIM works fine.
same problem in Tampa fl

hi community, i got my usa version of 1 iv and worked with mint-mobile (using t-mobile's network) to connect/activate. Calling/word text worked fine (image via text did not work), but no internet/data connection over 5g/LTE while browsing. Tech support could not get it working and escalated ... wondering if anyone would know how/what could be done. Thx!!
You must be missing the APN config on your device for TMobile. also, check if mobile data is enabled.
Here is T-Mobile info on how to setup Tmobile USA APN:

Not related to the post (getting T-Mobile service) on any of the Asian firmwares at the moment.
I flashed the Euro, US firmwares and no signal at all. The radio power in hidden menu shows as off.
Does anyone know if crossflashing with this model also flashes the radio modem?
Seems to have worked naturally for Xperia 1 II and Xperia 1 III.
Not sure why this doesn't work now aside from intentionally restricting the phone to the intended region model.
Mine is XQ-CT72 global version on US T-Mobil.
I'm getting 800+, but US version should be better because of better band selection.
Mine goes that fast only certain places.

I own the USA variant of the phone and I have absolutely no issues with 5G data nor wi-fi. The only issues I am experiencing is the fact that voice over Wi-Fi has not been provisioned. Coincidentally my phone also tells me within engineering mode that video over Wi-Fi is also not implemented. Sony wants to point the finger at T-Mobile and T-Mobile wants to point the finger at Sony.
Other than that I love this phone.

I have the correct APN that you mentioned and still no luck for voice over Wi-Fi. I spent over half an hour with a T-Mobile troubleshooting technician and she was not able to remedy the scenario. They have created a trouble ticket and forwarded up the food chain. They claim you will take about 3 days for them to get back to me so cross your fingers (VoWifi).

Ah, that is a different question. that means you are able to get data and your problem is only with VoWiFi which is expected. your original post question was totally different.
Sony blocks TMO VoWiFi in their software by blocking the network code in their settings. You will never get VoWiFi with Sony and TMO together unless you root and hack your sony build settings to enable it.
Your next best option is to move to GoogleFi that uses TMO network and you will be able to get the full VoWiFi service there since it has different network code.

Rats. I've been looking to upgrade from my Note 10+ on T-Mobile, and the Xperia 1 IV looked promising, but VoWiFi being nerfed is a non-starter for my needs. Curse the manufacturers for moving away from expandable storage!
T-Mobile basically did a bunch of farting around and could not provision Wi-Fi calling on my phone. I have confirmed from at least three people on XDA developers that the workaround is to jump on board with Google fi since they do support Wi-Fi calling provisioning.... Or somehow root your phone and find an engineering workaround.

It is Still a good attempt from TMO to try to help, It is really not TMO fault here as nothing they can do. Sony is at fault blocking TMO network code in their VoWiFi software.
Sony has decided to block this service from the second largest US carrier, wondering why Sony sales not picking up in the US
seriously genuine question......why is that so important? I mean, can't you just call a person on whatsupp or telegram or any other service? After all, it is just VOIP, right?

Since WCDMA and GSM are sunset, if you want to call someone or receive calls with your phone, you need VoLTE or VoNR. TG and Whatsapp are not that popular in the US, and imagine someone wanting to use their phone as a phone....
well, I get that. We still have 3G and GSM. And every time I work on new rollout things are more and more complicated because of all generations are still in use. Connecting to a unknown wifi every time seems very not practical and if it is not opened public network (which again is not great) how does that work then? I get it if you are at home/family/friends but my question is more like, no cell signal, jut some random wifi. To me it looks more like a patch then an actual service/solution for the lack of cell signal. Or is that something that you really can rely on?

The issue is when I'm in my local public supermarket there is no T-Mobile coverage in the building. There is Wi-Fi and I do use Google meet and other apps over Wi-Fi but if someone calls my phone number my phone will not receive the call. That is the point.
Someone would have to actually know that I'm in a no coverage area and utilize one of those other apps to reach me. If not businesses, job offers, local businesses that don't know me personally, someone new that I've met etc etc would never get through to me and I would eventually receive some type of voicemail message indication. That is unacceptable when you have children and other family members and friends that need to get in contact with you immediately.

Exactly the point, your phone number is the primary way many reach you. if your phone does not have any 3G\4G\5G coverage, then WiFi might be your only other option that gives people the ability to call you directly with your phone.
OK, but who provides wifi? I get that is is just a voip, but you still need internet connection. So instead of cellular it uses wifi.
Here, in many big business buildings or malls we have indoor base stations, sometimes it is combo indoor and out door. Indoor usually is set up as MIMO so all of the providers share the same indoor infrastructure.
Also, many of public places have a wifi but since we are covered with cell signal, nobody really cares about it. Mostly because you can't just connect to it. you need a pass from your bus ticket or your bill in bars or are greeted with front page of the mall that wants you to register and so on. So using wifi here is PITA, that's why I wonder how all that works there and why is it such a big deal.

There are many places that I have frequented where cellular data and cellular calling will not go through. In those places Wi-Fi is available. While you can use WhatsApp and other individual applications to make video calls and even voice calls you will not be able to receive native incoming calls when someone calls your regular phone number nor will you be able to use your native dialer to make a regular phone call if Wi-Fi calling is not provisioned on your phone. Unfortunately our phones do not get provisioned for T-Mobile Wi-Fi calling apparently due to some issue between the Sony and T-Mobile. So by switching to another carrier or mvno, Wi-Fi calling will be enabled reportedly.
UPDATE: Switched to Google Fi.... Problem solved. Wi-Fi calling now enabled.
That part I get, but still don't know which wifi do you use for that. For mobile network, there is a SIM that handles the connection between cells. Phones can't connect to any available wifi, right. So..... I get what it is, but as someone who works on cell towers installations and from perspective of wifi networks here and my knowledge I still don't get which wifi do you use in that case.

It can work on any Wi-Fi network that has adequate bandwidth. I can go to my local Publix supermarket....no cellular signal in there: I turn my WiFi on, I can make/receive calls with the native phone dialer. No cellular tower needed.
Even tested this at home.... I turned Airplane mode on, then afterwards I ONLY turn wi-fi on.... Calls can be made/received.
