Ok, I suddenly have lost LTE data and cannot make phone calls.
I have pulled the sim card and reinserted but I keep getting a popup window asking me if I want to connect to Global and not CDMA/LTE. I change the request to LTE and make sure setting is there.
It won't connect to 4G. and keeps asking about Global.
I am rooted and ROM'd with unlocked bootloader and have even tried my trusty stock image -- no go!
All of my ROM backups have the same issue and I can't place a call.
:crying:
Yes, my bill is paid and in order.
What can I do? I doubt VZW will help me since it is a Dev Edition and I purchased through Samsung, not them.
APN settings seem to be blacked out so I cant change. It does allow me to delete it.
HELP! I need to place calls.

If it persists across different roms it sounds like either faulty sim or for some reason your modem or kernel is corrupted. I would re flash modem. After that try to re flash kernel. If that fails a new sim might be in order. I presume you have checked with another phone to be sure it's not a VZW problem.

Thanks! I will try the modem route first and then the kernel route.
Although each ROM has a different kernel, so I don't think that is the issue.
Yes, no problem with VZW as the other half's phone is working.
Data works on LTE for Internet but can't place any calls and all received calls do not ring phone: goes into VM.
Edit: at Verizon and not SIM card. New SIM card gives me voice but no data. Says voice roaming.
Ok, here is the problem after 2 new sim cards: Data is showing as "CDMA RX1TT" I cannot get data or voice now. Says voice is roaming with a triangle.
Is this a software setting or hardware setting? Something has changed on my phone, despite changing from stock to ROMS, etc.
VZW store is at a loss and though the rep was good, suggested I call top tier VZW support tomorrow and made notes in my account.
So, any clues as to what could cause this? Is my Dev phone now shot?
If it truly is an APN issue i can post my APN from my Verizon SGS4 and you can use an app called APN backup and restore to push it to your phone or push it manually using root explore and then set permissions. Let me know.

You might have a corrupted EFS partition in which case you would need to restore a good copy of that. Some of the time its in LTE/GSM mode for whatever reason in which case you would need to change it to LTE/CDMA mode.

I had a "DUH" moment when I was in a similar situation. I had forgotten that I had enabled the hidden menu on my DevS4 and changed the "band" preferences to try and force the AWS band. This took the phone off of "automatic band connecting" and I was unable to connect to data. Once I remembered what I had done, I simply when back into the menu and switched from forcing AWS band back to "automatic". Just my 2 cents.

Hello Everyone! Sorry for the delay. Actually, this is what kinda occurred, as the 1/15 build of OctOs ROM which I flashed had an issue and it was posted on Facebook, which I didn't see until Saturday. It changed the CDMA subscription to NV and so even with stock or other ROM backup images, it carried over and didn't re-adjust. I had to reinstall that bad ROM, make some changes per OctOs instructions and BAM: all is well.
As you know on stock rooted, one cannot change certain settings and they were greyed out.
At least I got another backup sim card from VZW should I ever need to activate an older phone.
Thanks for everyone's help!

OK guys the title explains my predicament. I live in Costa Rica and am currently with the I.C.E for any of you that may be from here. I purchased a used S2 from a guy that bought it from Claro. So the first thing I did was get rid of the stock and I flashed everything like I wanted which is:
CheckROM v6
Using DarkKnight's Kernel
I'm using the KI3 radio but I have about 20 others and none of them changes my situation (coming up)
Original info was:
PDA-KG7
Phone- KG4
CSC - KH2
NOW here's the deal, my network icon has full bars but with an R for roaming. The phone works fine, I somewhat have data connectivity although SLOW, BUT when I go to APN settings there is nothing there NOR will it let me save a new APN, BUT I do get the 3G and H icons depending on where I am, I just can't program in a new APN or get rid of the Roaming icon no matter what ROM I flash, kernel or radio combination...
I have tried automatically and manually selecting my networks also, no dice...
I have of course already gone to *#*#4696#*#* and changed settings and tried all the variants but currently have it on WCDMA preferred.
I have also gone to *#2263# and tried all those variants but left it on WCDMA All Channels.
So I am more than open for any suggestions.
Go to Sammobile.com & search for stock firmware for your country/carrier (or just your country if they don't have any carrier specific firmware for your region), flash this firmware via Odin following whatever instructions Sammobile have for firmware downloaded from their site.
Once you've done that, check your APN setting & see if you have full connectivity. If for whatever reason your APN settings are blank (if you only end up downloading/flashing a country specific firmware only, for example), call your carrier for the APN settings and then enter these manually.
First thing you do when you have these problems is go back to stock & see if you can reproduce the problem or whether going back to stock fixes same

Thanks alot for your response MistahBungle.
Well on stock firmware is where I originally have the problem, that's the reason I began flashing ROMs and radios. IF I use a SIM from the original carrier which is Claro then all is well. BUT if I use a SIM from one of the other two carriers then the phone signal says roaming and I can't save any APN settings, no matter if I'm on stock firmware or any of the other ROMs or radio combinations that I have tried.
OK. Looks like we'll have to dig a bit deeper
So do you have baseband & IMEI in settings/about phone ? That issue of not being able to save APN settings with those other carriers sounds to me like a SIM or network issue. My first thought was it's a problem with the baseband, hence I suggested to flash a stock rom. But if that was the issue, you probably wouldn't be able to enter APN details for any sim/carrier.
Actually, now that I think about it. You know what it sounds like ? That the phone is network locked to your original carrier. That would explain everything.
If your phone *should* be locked (like you're on a contract where you only 'own' the phone at the end of the contract, etc), then I guess you can either pay the original carrier to unlock it. Or you can try one of the many unlock methods you can read about on here/apps you can get on the Market. Or if it shouldn't be locked yet it is, maybe ask the original carrier to unlock it.
You could also try flashing a specific rom for one of the other carriers, but I'm pretty sure that phone is network locked.

Ok just to clarify... all that makes sense, but what is ODD to me is that I don't think the phone is locked... I have full phone capabilities. I can make and answer calls, send texts, I even have full internet capability (even if I can't save any APN settings and there are none to be seen in the menu to choose from), I have the full speed of what I'm paying for from my carrier... the phone just won't let me SEE what APN settings it's using and in the signal it says R for roaming, but in networks it shows that it's connected to MY network...
Yes my IMEI does come up, BUT when I try one of those unlock apps I always get the message that it was unable to unlock it, but it's working with my carrier.
Ahhhh. OK. Yep that's a bit clearer now
OK. So we're pretty sure it isn't locked. That is really weird that it won't let you enter APN settings (regardless of which rom you're using), but you still have internet connectivity. Again, showing your network as the network connected to, yet showing up as roaming on the taskbar, is weird.
I've gotta say I"m pretty much stumped then. Haven't read a similar situation on here in the 4 mths I've been following the Q&A section of the board pretty much every day. Sorry I can't be of more help
Hopefully someone better qualified that me reads your post & can help. If you don't get a reply in a day or two, give it a bump.

Hey don't apologize, as you see no one else has ventured to give me a response either and I'm completely stumped myself. I looked for 5 days for an answer before I started a new thread because no one will go off on a noob for not searching quicker than I will, but I just haven't seen anyone with a similar situation on any forum anywhere...
THANKS AGAIN!!
Now to the rest of you devs, come on help a fella out and tell me what files I need to be looking for or modifying
Ok MistahBungles I got an update for ya... I decided to download a different firmware package (the PDA and Phone match mine but not the CSC), it's for Claro Argentina, BUT the ROM isn't branded when I booted it (the ROM the phone came had a CLARO boot logo (another reason I started looking for a different ROM)) and THIS ROM automatically has my APN settings in the menu without me doing a thing and the R in the signal is gone....
So now my question is how do I go about flashing the ROM I wanna use which is CheckROM but not lose my new found freedom (I ask because I'm not sure if this is a simple radio issue)

The Phone maybe Network Locked.(Not sim locked) As taken from gsmlocker.com:
Q. What sorts of locks are there?
A.
- lock phone to SIM
- lock phone to OPERATOR (network lock)
- lock phone to CODE (product lock = offer lock)
If your phone is locked to the sim you cannot use any other sim than the one you have: SIM broken makes phone useless.
If your phone is locked to an operator, you can use any SIM from this operator in your phone. You can switch between contract and prepaid as you wish, but not to a different operator.
If your phone is locked to a code, the phone checks a special "password" (GID) on the SIM that must match your phone. Providers often use different passwords for contract and prepaid.

OK I get your point BUT the phone if fully functional, I'm using a SIM from a different carrier, I have a data connection, make and receive calls, the whole nine yards, it just won't let me see what APN setting it's using and the R symbol is in the signal... once again, IT IS allowing the use of a different SIM from another carrier
Yes its the same as me! I have the R showing as well.(if you put the Claro sim in the R will disappear yes?)

BREAKTHROUGH... I think that I have found the culprit... since I live in Costa Rica I use Market Enabler... apparently whatever it changes is causing the problem, which is weird because I have 3 other android devices, I use the same app on all of them and don't have this issue... NOW I'm really scratching my head... guess I need to contact the dev?
Ahhh. So Market Enabler is changing the CSC which is causing the network settings to disappear/barf.
Nice work finding the source of the problem Yeah tell the dev. Hopefully they can find some sort of fix/workaround so you can still use Market Enabler.

Well I just through and installed and tried ALL the market unlocking apps and they all apparently do the same thing and causing the same result, my phone thinks it's roaming, so now the head scratcher is why my other Android devices don't behave in the same way? This is my only Samsung. The others are Dell Streaks.

Sorry to bump this up, but I'm having the exact same problem. I was wondering if you ever figured out how to fix it.
I have a HTC Sensation and it happened to me right after I upgraded my custom kernel version to a newer one.
I never installed Market Enabler nor Market Access but when I check the SIM info it shows incorrect MNC and MCC values which
I can't change... they won't save in the system options.
I thought maybe my SIM card is screwed up, so I'm thinking of getting a new one from my service provider.
I just have to check it on a different phone first.

Ok, forget it. My SIM card was having issues, got a new one from my carrier. Everything is working fine now.
I'm trying to use my iPad sim (converted into a regular sim card) in my note, but I am unable to use the APN "broadband". Everytime I create that APN, it will automatically delete it off the list. It seems like AT&T is blocking that APN from being used. Is this possible, or a way around this?
Thanks

Are you rooted? I don't have an answer, but I suspect the solution involves being rooted and freezing an AT&T management .apk that is deleting any APNs that you add.

Yes, I am currently running TPC NOTE V2.
My first contribution to the forum
I got the ATT Note last weekend off second hand, so no contract.
I want to use it primarily as a tablet with data plan (google voice can serve as phone if needed). So I want to try iPad data plan.
I got my iPad sim activated for a monthly plan, but as members noted, that for some reason, the new APN setting can not be saved for some reason (can we blame ATT?). So you can not use the iPad sim directly.
I tried couple of ways, and finally figured out how to do it on my Note:
(1) Create the new APN as previously instructed (call it "iPad" or whatever), with "phone" as the APN setting. Save it.
(2) On the APN list, select the new one, so the default AT&T PTA is grey out, and the new one ("iPad") is on.
(3) Now, change the APN from "phone" to "Broadband" (Sorry I forgot this important step last night!)
(4) Then, instead of saving the change (which would fail), I jumped out of the setting and go straight to home, then web browser to click a link. It might give you an error the first time, but when I clicked the link again, it would eventually start working, and the 4G icon showed up on the top menu.
I wen back to APN setting. Found the new setting "iPad" was gone. However, I did notice the default APN setting (AT&T PTA) remained grey out (not selected).
So, it seems if you force off the default setting, you can go straight to 4G network with iPhone's data plan.
I disabled the cellular network and reactivated it. The connection still worked, so hopefully it will last.
[Update]: Sorry I forgot the important step (3). I tried again, and the whole process works. Yes, I have the phone unlocked already for T-Mobile use (paid $25 online to get the unlock code. Not sure if it is necessary for AT&T data sim card, though).
i think
I think your note has to be unlocked .thats only way
iPad Sim
I am using iPad SIM in note and its working fine. I don't get LTE but HSPA Speeds. I picked new SIM from AT&T Store for my iPad and activated under different email now using it with $30 3GB Plan. I have 'broadband' as apn. My note is unlocked running SAUROM RC 6. I had issues with RC 7 so reverted back.

It just can't be on an AT&T based rom. Since Saurom rom is based off of Rogers, the apn "broadband" will work. Has nothing to do with unlock, it's the software that prevents you from using that APN.

You are now able to use LTE on the note since AT&T now has a plan for the "New iPad". You just need to change the plan in the online management. Just change the IMEI to the "New iPad". The APN will still be broadband.
I found a IMEI from some person selling it on eBay

Thanks much for this ....I could not find any other solution so far.....I appreciate you writing this. It works.
Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
Can I install a I-9505 ROM on this and then would it pick up the GSM signal for voice and data. Please help.
I don't think your Verizon rep is correct. I bought a Verizon S4 just before going to Europe for 1 month. I used first a gsm SIM card from Germany, and then a gsm card from France. I had to add APN's to get data (I used "offline sim APN database" from the market to help get the necessary APN info), but had no trouble with voice or data for my entire trip. The gps and navigation services on the phone were extremely valuable on a couple of occasions, as was the wifi hotspot. In France, you can purchase 2 GB of data service for 20 Euros. I checked with Verizon global services ( 908-559-4899 outside the US or 800-711-8300 from inside ) before I left, and the Verizon S4 was sim unlocked out of the box. They did not make a big deal of my plan to use other SIM cards either.

Installed WamanLite I9505 ROM
Hello All,
I found that Wanam Lite I-9505 ROM can be installed on Verizon S4. I installed it and patched it with Loki-Doki patch to boot up as I got the Verizon Software error. Yet my phone doesnt pick up the GSM signal for voice and SMS. It picks up the signal and I am able to browse internet on it but no calls or SMS. Please help...!!
Is there any way that I can install or flash a regular GSM radio over the phone ? Or tweak it in someway to use the GSM signal as primary for voice and sms.

I have also Verizon's S4 (i545) and use it in GSM network with only one small problem - it will not send SMS with in-ROM SMS apk to international-formatted numbers (+380-XX-XXX and so on), but send without problem to local-formatted numbers (XX-XXX...) All the rest is working good.
Could you tell me please - how did you get to install i9505's ROM on your device? I have also Verizon's error after installation, and don't know how to run it...
Hi I too have the vzw s4 in india.. and niether voice nor sms is functioning on it.
By rooting it and installing apn manager I was somehow able to get the data 3g working for vodafone ind.
I too am struggling to find a solution to this.
Ive haventvyet flashed it. I came across a guy who said he will be able to get it working but somehow I havent yet been abke to follow up with him.
Guess we both are on the same boat.

I too created a post seeking help in this regard but didn came across anything concrete yet.
Everyone out here believes it to be a world phone and some have even been using the gsm network in europe but its not working in india.
Ive failed to understand that how come its detecting signals with functioning data is not working on either voice or sms.
Tmobile and atnt gs4 guess have this service menu from where they can be network unlocked explicitly..but unfortunately I havent yet come any such thing for vzw gs4.

I tried installing the ARHD 2.0 ROM but still the same issue persists. The phone picks up the signal for data but when tried selecting network manually or automatic using the GSM / UMTS option, it says disable data to search networks, when data is disabled, the phone shows available networks says phone registered to network but the status still says Emergency Calls Only. Also if tried dialing a phone it says no network available. There has to be something in the modem settings which can be tweaked through the service menu which will change the use of GSM for voice and data and not use CDMA.

Did you do a full wipe when flashing ROM? It is mandatory. You will lose all your data though. If there will be no changes after full wipe - then try to install this card into another phone and ckeck if voice calling is working.

I did a full wipe. I have 2 Galaxy S4's and also an Optimus G. The card that I am using is my regular SIM card so its not an issue with the card for sure. The ROM was installed on both the phones and neither of them picked up the signal for voice and SMS.

Ok. To go and chose type of radio-band you may install Battery Monitor Widget from Google Play (well, the main purpose of this app is different, but it is what comes first in my mind). Put it's widget on the desktop, open it and go for bottom right button, named Test. There you can first menu (Device Info) and there you will be able to change all variations of the radio bands and their combinations, available for i545. If non of the combinations will help - mosty probably your operator works on unsupported for this phone cellular format.

I have the Phone Info app which allows band select. Tried on all possible modes. Same issue persists. Strangely the Note 2 purchased from Verizon works flawlessly without any mods or changes. I am thinking of giving to some professional phone guy who may have code level flashing or modding tools to try and fiddle around with settings of the modem or the radio to pick up the signal here.

Hey phrozenwire, I am able to use both voice n sms now in my VZW GS4.
And I literally did nothing to make the voice n sms functional. I too had troubles for like 2 weeks and it didn work for me then.
I rooted the phone to add apn settings and the data got activated. But today morning when I woke up ... surprise surprise .. it began to work.. rcvd sms and calls and I was so happy. . Last I remember I switched on the power save mode and my cell fell down twice and guess it did the trick for me.
Thanks all for your help and comments.

Hello from a noob. I have done the saferoot, text edited the sales dat to AWS and changed the other file (forget the name) from OFF to ON. Basically I switched the IMEI on my Metro account to a 545. I kept the same SIM. The store says there demo SIM does not pick up the internet either. The internet worked for 2 minutes and now there is no logo (4g lte, H+ etc) and no connection to the internet at all. I have tried going into the bands etc. but I think I'm missing something (I guess obviously). I have done "everything". Updated the APN settings etc. etc. It is stock rom except the root and the minor text edited changes. It is on 4.3 android. Can anyone out there please tell me how to turn off the stupid VZN LTE band option (I think that is my problem) however when I put in the *#276... command it doesn't pull up the menu that lets you access the band option like I've seen on Youtube. It gives me a different menu with UMTS at the top. I still haven't found the turn off the VZN LTE option. Any help at all would be appreciated. The dialing and text messaging work so it's a clean phone but for some reason the phone is blocking my damn internet. Thanks for the help.
When you installed the MetroPCS SIM, did you configure the APN to use their network?

Yes sir. I have done it all and nothing has helped. My only thought is finding that switch for the Verizon band or something else in the programming but I can't get to that damn menu. And the *#276.. number is not working on the phone anymore either.
So for those interested that may have Metro and are having the same problem I finally just updated the phone with the stock 4.4 firmware (clean wipe and all that) with Odin and it now works and the LTE no longer shuts off. After hours and hours of agony I finally did it. I tried rooting and everything on 4.3 and I don't care that I lost root - I'm just glad it works now. I do appreciate for what it's worth all the information on here and best wishes to you guys for all the future modding, unlocking the bootloader and all of that. See you around.
I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

Thank you so much for your reply. I looked through the software section in the about section. I found the following codes about the rom.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
