Hi everyone!
I've been having connectivity issues on my Sprint GNex ever since I flashed my latest ROM. I haven't been able to send any MMS, and any time I try to use the web I get error messages. I think that I've nailed down that it's an APN issue, and I've tried to follow the steps to resolve it.
I've tried APN Backup and Restore, but since I'm running 4.3 that doesn't work. I've also tried going into Settings > More > Mobile Networks > Access Point Names, but on every single ROM that I've used I have not been able to find the Access Point Names screen (as in it does not exist). Is there any way that I can get the APNs fixed an alternate way? Maybe something that I can flash from recovery? I feel like I've tried everything!
Do you have the ability to add a new APN?

Hi Everyone,
My Phone:
Lt15i
Baseband 70
Stock kernel with CWM
Arconium ICS
My Problem:
After going to a custom rom and kernel from a complete stock setup I cannot get a data conection on my phone. All other features work perfectly (Call, sms, wifi etc) just no 3g/2g data connection, or icon in the status bar. the Settings menu indicates it is turned on.
I have exhausted all available options regarding kernel/rom troubleshooting including a complete reinstall on the above rom/kernel. I also experienced this problem with other roms and kernels.
During setup I follow the setup app and download the apn settings for Crazy Johns (my carrier) and they report as being installed.
My question:
If anyone who is using Crazy Johns currently and has it working could please post their apn settings (text or screen shot whatever is easier) so I can compare these to mine and change as necessary.
Any and all suggestions for fixing this are welcome.

Yeah, tried getting it sent to me, entering it in manually, even tried entering various variations of it I had found on the net. Still no connection.
Everything worked perfectly when it was stock, and when i first flashed a new rom onto the phone (arconium 8.2 i think) it worked then too. but every rom since it hasn't.
I'm still quite new to this and my knowledge isnt too deep yet.
Could flashing roms or kernels effect the serial numbers of my phone or something and now my carrier doesn't recognize my phone?
I do still receive calls and sms...
It's got me beat!

Hmmm I think you phone is fine must be just the settings.
What does it say? Any errors? Can you grab a log too see if it says something there. Check my Sig for how to get logs etc.

Well props to you, you were right in suggesting it was settings related. I tried a different sim card from a different carrier and after following the setup procedure I had a 3g data connection. This of course means the problem lies with my sim card/carrier settings and not the rom or kernel.
Good day Gentlemen and Ladies,
So, as you the title states I cannot connect to mobile data (3g). (Before posting this I had done my research trying to find a solution and I cannot find any solutions) Let me tell you a little bit about my Galaxy Nexus SO originally when it was purchased it was a yakjuxw and I flashed to stock yakju-4.0.4 by this methodI can not link the video atm as I am a noob here) (I am sure that I did not skip any steps). I updated to android 4.2.1 all OTA updates and since that day I cannot connect to mobile data. I am pretty sure this is a software issue unless its a coincidence that my device fails on me at this point in time. Everything worked fine before i flashed it. I have tried going into *#*#4636#*#* and making sure my network type is correct as well as the radio band as automatic. I tried rebooting the device, I turned on mobile data and waited for +2hours for it to connect and nothing. I am sure I did not reach my mobile data limit as it is the beginning of my billing cycle. So, if anyone has any solutions would you be kind enough to give me a link or instructions on how to fix this problem. I recently also got double my data free of charge (from my provider) and I can't even use it Lol... Thanks!
1. Settings -> About Phone -> See your baseband? Does it exist or does it say Unknown?
2. Attempted to reset APN?
3. Tried your SIM card in another phone? Does data work on that phone?

Man you are a genius thank you. It was an APN problem. I think when I flashed it the server # and port # went missing or something so I added those and 30 seconds later it is all working! Thanks again my friend. And for anyone who has this in the future you can access you APN settings->more...->mobile networks->Access Point Names (and APN vary on provider)
Just upgraded to 4.3 today but my data services don't seem to function well. Can someone please help me?
Same problem here..
Looks to be an issue with TWRP, have either of you tried the latest CWM recovery? I was hoping to avoid it since my nandroid backup was TWRP (I'm honestly not sure if there's a difference) but a few posts in the main threads are reporting a similar thing.
EDIT: Nope, same issue, at least for omnirom.
I take that back, it does work.
Go to Settings - Network Connections - More Networks - Mobile Networks - Access Points Names
Check and see if you have the APNs from your provider, they usually are 3 ([Provider] Internet, [Provider] WAP, [Provider] MMS - in my case). Make sure [Provider] Internet is selected. When I usually re-install some ROMs, the WAP APN is selected by default and that will show me the 3G data icon but it will not let me access internet resources with my data services.
If by any chance you are missing the Internet APN, search a bit on the internet for your provider APN settings for internet access.
Hope this works.

It just acts like there's no SIM card at all. I don't understand it completely, but CWM is doing something that TWRP is not (or vice versa) and is causing this issue. Took my 7105T from virgin vanilla stock to the omnirom 4.4.2 nightlies yesterday and when I flashed from CWM the issue was resolved.
That said though, I'm unsure how this will affect omnirom's updates so I might need to switch to cyanogenmod. Shame, because I do prefer TWRP.

I don't know what you guys are talking about but I can't even access the APN settings, its invisible. I have a SCH R950 note 2. H2o wireless already took my money but told me I needed to unlock it, even though I can't unlock a CDMA phone. im so confused because it is quad band and has sim card slot but no one can unlock it and I cant find how to flash to h20
I tried flashing a custom ROM for the first time last night and so far I am really loving it. The only problem is, after flashing the CM11 M7 ROM it wont access any data over the cell network. I did figure out that if using Titanium Backup I restore my stock ROMs 4.3 data only from the Phone/Messaging Storage (SMS/MMS/APN) then reboot the network data does work. However, this causes the SMS to cease functioning. As soon as any app (default messenger, hangouts, 2-3 others I tried from store) tries to open it immediately crashes. Interestingly, it also will not allow me to restore my SMS records using Super Backup at this point. If I go back into Titanium backup then wipe the data for this process then the SMS starts working again, but all the old messages have been cleared, and as soon as I restart the phone the Network data is not working again.
Any ideas on what to do? I am wondering if maybe I need to adjust something in my APN profile, though I have absolutely no idea where I would get the information to do this.
This is what I am working with:
Phone: Samsung Galaxy S3 i747 (AT&T) -- [though currently I am using a TIGO sim card in Guatemala, wonder if this could have anything to do with it? was not a problem prior to switching the ROM though]
ROM: cm-11-20140608-SNAPSHOT-M7-d2lte.zip , the Cyanogenmod CM11 Snapshot lte release from yesterday
Android Version: 4.4.2
Baseband Version: I747UCUEMJB
Kernel Version: 3.4.91-cyanogenmod-g9b9605b8 [email protected] #1
Anyways, only having one or the other of my network data vs sms working is not really an option for me, so need to figure something out.
Thanks!

I apologize in advanced for not answering your question.
Is your issue that you cannot even get a signal with CM installed? I am also having the same issue.
Did your phone get signal/mobile network with the stock ROM? I am unable to find out if mine will work right now because it would take me a few days to download the stock ROM image...
Will be following this thread...
Mike
Have you checked that the APN on your phone is the right one for your carrier? Google search apn tigo guatemala galaxy s3 Many useful results will come up.
Ok here is how this played out. I did just need to reset then re enter the apn info for tigo in Guatemala. I actually managed to pull this info out of my pre flash backup from when I was using the stock Rom, then wipe the data for the process mentioned. This restored sms functionality and I then was able to manually enter the apn info (if anyone needs the Guatemala tigo apn info just post here and I can grab it when I am next at my cpu). I find it interesting that the apn info was automatically present and correct when I was using the stock Rom, but when I flashed cm11 over it was not there.
Just arrived back in the US and popped in my AT&T SIM card, everything worked fine right off the bat with it.
In answer to your question, after flashing cm11 I did have signal, but only for calls and sms. The data component of the network was not recognized.

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.
This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.
Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.
What APN (Access Point Name) are you on ? Also what is your Preferred Network Type set to ? Its located in Settings > More I think.(I don't use Stock Firmware)

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here
I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..
Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.
I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.
