[Q] Mobile Data Issue!

Hey there! I have a Verizon Galaxy S3 running Cyanogenmod 10.1 nightlies. I was just sitting there watching tv, I picked up my phone and saw that my service bar was empty and had a little "R" over it. I tried using the phone and there was an automatic answer saying "Welcome to Metro PCS. You are not a registred customer". WHAT?? I'm on Verizon with a CDMA/LTE radio. As far as I know there is no HSPA radio in my phone. I restored back to a nandroid backup I made on new years eve and that did nothing. So I flashed a new radio and now instead of calling at all It reads "Mobile network not available" and the little "R" is gone, but the service bar area is still blank! What do I do?
Edit: Flashed the latest nightly and new gapps, and now 4G seems to be working, but the phone crashes every time I call anyone, and no texts can be sent through or received.

Here's what you should do. Go to: Verizon Galaxy S III Android Development --> Sticky Rollup Thread! (Are you in Panic? Look here)--> [Tool][Win] Repair IMEI & Roaming ERI issues and follow the directions in that thread. It will send you back to stock, but once you're there you can start from scratch and be in the clear! Hope this helps! :good:

Did you flash a Metro PCS nightly instead of the verizon version (d2vzw/sch-1535)? Also did you... settings> more> mobile networks> and change CDMA Subscription to RUIM/SIM and System Select to Automatic then reboot?

[Q] Not registered on network after 4.1.2 installation.

Hey all,
I have a Samsung S3 which I bought today, the guy I bought it from said he originally bought it on the Vodafone network (UK) but he had unlocked it. When I put in my T-Mobile sim in it worked fine, the phone was running on Ice Cream Sandwich 4.0.4. I installed Jelly Bean 4.1.2 after watching a Youtube video successfully.
However, when I put it my sim card, I can use the phone but it says 'not registered on network' when I try to make a call, and when I pull down the menu it says 'emergency calls only'. Internet works fine on WiFi.
I checked the Imei number, its all correct apart from the last two digits have changed, which I checked with the Box I got it with. What have I done? I am a noob at these things I hope I haven't messed up my phone Please help.

You should verify a few things. Are you 100% positive that you installed a tmobile rom? There are many varients for the gs3. For example i'm on atat, I can flash a sprint rom which will boot up but I cannot get data to continuously work. If that doesnt apply then go to settings menu>wireless&network>mobile network. U should see an option for selecting network provider. Select manual search and give it a few minutes to find the networks and choose your network. Reboot the phone after and it should be good to go. If after that you don't have data service then you need to verify the apn it's correct. It's located in the same mobile network menu. Good luck.

[Q] [Solved] APN settings USA AT&T GoPhone

Hi
I am currently in the US for holiday. Bought two prepaid att go phone cards already in Germany and activated them. The Data connection in my wifes SAMSUNG SIII mini (stock) works as it should.
In my HTC ONE SV I only get EDGE working. No matter which APN settings I use as soon as I switch on something else as GSM only in Network data plan.it disconnects completely from Mobile and states "Service not available"
My SV is unlocked and rooted and running with the Russian ROM
Any quick suggestion what can help,
Edit: I went to a AT&T shop here. They were very helpful but couldn't get it working. Tried more things and at one point all APN settings were gone. After that I tried for the first time the "Reset to default" and it loaded the ATT Phone settings.
After a restart everything works. I have here with H sign in taskbar a download of 5Mbps and upload of 1Mbps.
I attach the screenshots of the settings

ROMs for Global/GSM roaming

Hi everyone,
I have a d2vzw running Carbon ROM Kitkat. I spent the weekend back in the UK and enabled global mode, which connected to Vodafone's GSM/HSDPA network using the original Verizon SIM. So I had phone and SMS service - no problems at all.
However, I couldn't get a data connection. It was connected to the HSDPA network (enhanced 3G). Under Settings-->More...-->Mobile networks there is the option ("Access Point Names") to choose an APN. However, none showed up. I tried to add an APN manually, but as soon as I set Vodafone's MCC and MNC, it refused to save the APN info.
Oddly enough, the correct APN settings are all on the phone in Carbon ROMs "apns-conf.xml" file, they're just not showing up.
I tried everything to remedy this, but no luck.
So, here are two questions to harvest your collective wisdom:
First, is there a solution to this? I like Carbon ROM, but I have to have global data access for my work. If I can get my d2vzw running Carbon connected to international GSM networks and APN for internet, then I'd really like to.
Second, does anyone know of a KitKat ROM that DOES do this properly on the d2vzw?
Thank you so much,
M

I haven't checked in on AOSP ROMs in a while, but last time I did, none of them could do this, you need to run a Touchwiz-based ROM. AOSP ROMs like Carbon use a reverse-engineered radio interface which is not quite as good as the Samsung one which is included with TW ROMs, and this is one problem with it.
The bottom line is that if you want all the hardware features of your phone to work, you have to use a TW-based ROM, because Samsung hasn't opened up the hardware.

Thanks, Jacquestrapp. That's helpful. Perhaps I will flash a TW-based ROM and then keep it as a nandroid backup for when I go travelling.

I have been using my Verizon S3 in the Philippines as an international phone for months with excellent service. I am able to connect to the GSM network and transmit data at H+ speeds. I am on CM 10.1.3 official on Baseband MF1 and have been able to successfully switch to GSM using the PhoneInfo app. To assign proper APNs, I use the HiAPN app. Be very careful with Phone info: I once broke my connectivity messing with the settings too much ("Select radio band") and had to revert to Twiz and turn on the GSM bands using the "secret menu" to turn those back on. If you have a Twiz backup, try dialing *#2263# to choose the bands your phone has access to (seems impossible on other ROMs) if you keep having problems.
The thread here (see post 106) is enormously helpful.
The info about Twiz and reverse engineering is useful -- I haven't been able to get reliable service beyond CM 10.1.3 (very low signal, inability to send SMS, but somehow can receive SMS and voice calls), so I have been sticking to 10.1.3, unfortunately. I want to upgrade to 4.4, but haven't been able to do it without breaking GSM functionality. Has anyone gotten GSM and data to work on a 4.4 ROM?

Can't turn on data using the Verizon G5 on AT&T?

I just bought a used Verizon LG G5 (VS987), however my carrier is AT&T. After putting in the Sim card, calling and texting works but when I go to turn on mobile data in the settings, I get a popup that says "Add Mobile Service Please contact Customer Service at (800) 922-0204 for assistance."
I have called both that customer service number for Verizon ^ and also AT&T. I made sure that my IMEI was updated on our AT&T plan, and I have the right APN settings put in. When I called Verizon, the guy didn't really have much to say except that the device is unlocked but full access to features can't be guaranteed, and I am aware that Verizon and AT&T use different wireless bands, which he explained, but I should be able to at least have some kind of data. We both agreed that this is just some piece of Verizon software keeping me from using data, and he suggested rooting the phone to get a workaround.
One suggestion that I saw in some forums and tried was that resetting the network settings in Backup and Reset does turn mobile data on by default, however I get the same Verizon popup as soon as I open any browser, and other apps just say there is no connection, although when I do this I can see that I am getting either HSPA or 4G data, it just seems like it's being blocked by this Verizon stuff. Messing around with other setttings such as Data roaming and System select didn't change anything.
Does anyone have any experience using a Verizon G5 on AT&T? I saw a video of someone demoing T-Mobile 4G data on the Verizon model, and another user on XDA said that he put in his T-Mobile sim and it worked perfectly. My best guess on where to go from here is to unlock and root, and see if I can install a custom rom to get around this. Does anyone know if there is a stock LG rom without all of the Verizon bloatware installed, maybe a stock rom for the unlocked model of the G5? Any suggestions on how to get this to work are appreciated, and I think this is posted in the right place, I'm an active reader on XDA but this is one of my first posts
Thanks to anyone that reads all of this!

Update: I reset the phone to factory settings and set it up with the sim card from AT&T in it. Since then I can turn on mobile data, and the notification bar shows I have data (mostly HSPA), however I have no connection when I try to load a webpage. Tomorrow morning i'll stop by the AT&T store and see if there's anything they can do.

Did you add the correct APNs for AT&T in the phone when you put in your sim? you need it for internet and MMS
Did you which it to Gobal or other option that is not LTE/CDMA?

Same problem here

Was your problem solved? I'm having the same problem with another Verizon LG Device. If it was solved, what did you do?
