The APN issues thread

Hi everyone,
I figured I would start this thread to give everyone a place to post their APN issues/fixes/work arounds to maybe cut down on the questions being asked in the development forums. I will include any of the fixes/workarounds I have seen so far and try to keep this thread updated with any new ones that come about. I have learned so much on here on XDA just by searching and reading, I hope that this thread can do the same for anyone else looking for answers. Thanks/credit for all these fixes/work arounds goes out to all the OP's (special thanks to Martovitz for inspiring me to write this) Again this is just random things people have tried that have worked for them,this is NOT a step by step, THEY MAY OR MAY NOT WORK FOR YOU, and they are in no particular order, everyones phone is different:
APN Voodoo:
1) Try Holding power button down while holding volume up to reboot phone.
2) Try pulling battery out while the phone is on, let it sit for a minute, then restart.
3) Try toggling airplane mode on wait a minute, then turn it back off.
4) If simple user is selected in your APN menu try selecting T-Mobile. If this fails try deleting simple user APN.
5) Go into settings>wireless>mobile networks. -let it search, pick one, let it 'error' then select the 'select automatically' option -wait a second, press back to the home screen, wait two more seconds APN issues disappear
6) Run fix permissions in ROM Manager
7) Replace Sim card,try new UICC sim card specifically for 3g/4g devices.
8) Try flashing new ROM while in a good T-Mobile area (ie full bars of reception) to register on network
9) Try reinstalling ROM using this process:
a) Wipe cache
b) Wipe Dalvik
c) Flash ROM
d) Flash gapps
e) Fix Permissions
f) Reboot
10)
a)Turn on WiFi and make sure you're connected.
b) Go into the Market, search "APN Backup".
c) Download the program called "APNsBU (ROOT)"
d) Open the program and click on the "Backup APNs" button.
e) After that's done, click on the "Restore APNs" button. It will prompt you to reboot your phone.
f) After the reboot, open the APNsBU program, click on the menu button on your phone and click "View APNs".
g) You should be able to see "Simple" and "T-Mobile US." Turn off your WiFi and you should be good to go!
11) The fix that's been working for me 100% is to just delete the APN type on both the T-Mobile US and Simple and then make sure T-Mobile US is selected
11) Use ROM Manager to "Reboot into Recovery", once recovery boots simply select "reboot system now" and let the phone boot back up. That's it, when the phone boots back up the apn settings will be restored and data will be working like it should.
***Disclaimer: I am in no way responsible for any damage you do to your phone trying these fixes/work arounds***

pretty awesome thread, thanks for sharing your experiences

Would someone be willing to type up or link to the reason why the APN problems manifest? I really appreciate the list of (supposed) fixes, but I'd also like to know why the problems exist in the first place.

I honestly don't think anyone really knows, but I'm willing to bet with the release of official gingerbread update these problems will disappear
Maybe if everyone starts posting the problems their having and where, when, why, and how they started we could narrow it down

APN Issues only occur with not stock roms for me.

Apn issues:
They basically give u no data and when u go to apn settings there are no presets. This usually doesn't happen on first boot on cm. But when u reboot everything dissapears. Some fixes use to work for me but now data works when it wants to

Exactly my problem or when I am on wifi and turn it off I don't get data back either

See and the really weird thing is you get people like me that have never had any apn problems .... but I have only flashed Cm7 rom starting with nb#32. I haven't used any other roms.... maybe that's a possible reason why i have no apn issues.

Have u tried apn'sBU? It fixes every time for me. Usually happens first reboot after new flash (not the reboot out of cwr).
Yah, it's a crazy issue. Cm7 is the only rom I've flashed, I did a few full wipes around nightlies 38+ figuring it would have to help. Made no real difference.
Good luck.

My data/apn fix...
Okay, I guess this isn't technically a "FIX", but it WILL get your data working again until the next time the apn settings decide to mysteriously disappear.
Use ROM Manager to "Reboot into Recovery", once recovery boots simply select "reboot system now" and let the phone boot back up. That's it, when the phone boots back up the apn settings will be restored and data will be working like it should.
Wish I had an actual fix but this is MUCH better than nothing, and in my opinion easier than taking my case off and pulling the battery every time.

Any time I'm having data or signal issues, this pretty much fixes it.
3) Try toggling airplane mode on wait a minute, then turn it back off.

Having the same issue here with cyanogen ... Tried many build ... I'm adding my APN (I'm sure it's correct, it's working on stock firmware) But on Cyanogen, no data (4G) HSPA+ network ....
Tried removing battery, airplane ... impossible to get data working...

Please help - Cyanogen Nightmare! Can't connect to cell network

EDIT: RIGHT AFTER POSTING, MY PHONE RANDOMLY STARTED WORKING. I HAVE NO IDEA WHAT I DID BESIDES POST HERE. MAGIC.
I installed Cyanogen version 7.2.0 just fine using the guide that was found here: http://www.mrmuh.com/2012/01/update-a-motorola-milestone-from-motorola-firmware-to-cyanogenmod-7/
However, the next morning I think I enabled the 2g/3g switch widget - and then my phone entered into a constant and continuous loop of "com.android.phone has unexpectedly closed" - and couldn't connect to cell service.
In a panic, I searched everywhere for fixes. I then tried a few of the fixes which instructed you to download "sqlite editor" and do some edits to the settings file. I did this, along with a couple of other network edits, resetting them to "0" instead of the "1" they were currently set to. No help.
Finally, I went into the Open Recovery system and did a full reset on cache/factory reset/etc. and then rebooted into cyanogen. Now my network won't even connect for a half a second and then crash like before - just straight up NO CONNECTION.
Now I've went through and attempted changing back some of those settings I messed around with in Sqlite - but to no avail.
Anyone with any ideas on how I can get an operating phone again, please let me know. I noticed I still have all my apps from previously, so I don't think I'm really factory resetting the phone. That could be part of the issue, I'm sure....I am very depressed and hoping for a miracle!!

Look into installing minimod recovery and then flashing the correct radio for your location after a full wipe.
If you do a google search you should find minimod. I'm on my phone or I would just link you.

OK Thanks for your reply.
However, randomly, just after I posted this - I looked down and my phone had a full 2G Connection. Went into baseband settings, enabled 850 band 3G, and now I have full 3G connectivity.
I have no clue how this happened. XDA forum is magical?
Thanks again for your reply, but thankfully I don't need the minimod suggestion as of now!!

You're welcome. You might want to go ahead and install minimod though. I made the mistake of not having it installed and flashed a new rom without the ability to select bands and was without a phone all day. It's better safe than sorry.

How to get out of ROAMING? (after flashing 10.1 official)

So...I went ahead and flashed the Dec 24th official 10.1 release with data working. I flashed with TWRP and it went smoothly. I couldn't activate the phone because it was stuck in roaming. I tried what ever I could do but could not get out of it. So I resorted back to full stock from verizon locking and un-rooting. Did that and I also flashed a stock radio. Still cannot get out of roaming mode.
Any suggestions? Kind of in desperate need of data to get a working phone!
Thanks in advance. I'm sure this problem has come up among many of you.

I thought flashing "[OFFICIAL]CM10.1 Official Nightlies for D2VZW GSIII (12/24 Official Data Works)" was the latest one. How would I go about "fixing" the mobile settings? via the settings menu? I cannot access that menu if I need to go there. I need to get past the activation screen. Also I am not so sure on performing the four corners trick in order to get past that screen.
thanks

i just posted a fix topic for this but here this is how i got mine to work after flashing CM10.1 the 12/24
If you remove ur sim card and boot up and connect via wifi, u can then register and set up the phone. then shut down put sim card back in and boot up. go to system settings -> More... under wireless and networks -> mobile networks -> CDMA subscription and choose RUIM/SIM (NOT NV)

I didnt see a responce from here but ill do my best, flash back to the stock ROM using ODIN and you should be put back into the operating system still in roaming mode then you dial *2767*3855# as soon as you hit the # your phone will download a file and re-provision itself which will fix the roaming error.

GPS issues

My s3 has been acting funny lately.. the GPS seems a little wonky. I noticed when flashing a 4.2 rom.. my GPS seems to want to work..then just won't get lock on its own..I have to toggle GPS on/off to force it to work..and even then its not very solid. When I flash back to a 4.1 rom.. it seems to work. It gets lock on its own..but even then..I notice a strange inaccuracy.. I use My Tracks..a free GPS app..when running side by side with my tablet..the location seems weak on the phone..while driving in a straight line..it shows me on the other side of the highway..but near..not too fat away..then sometimes it seems on track. Now on the tablet..its dead nuts accurate.. showing me driving straight..not like I had a twelve pack first..lol..could formatting the SD card of damaged something? I wonder if all the flashing I do screwed something up..

My only fix
I have had the same problem. On CM10 my GPS works flawless but when I go to CM10.1 the GPS only works for an app if I toggle it inside the app. I have only found one fix so far for it to work in CM10.1.
Here's what I used from buhohitr (post):
Download the zip, unzip it, then copy the 2 files (gps.conf and certificate) to /system/etc of your device, reboot and try out your gps. Let me know how it goes. You must be rooted to do this.

I read on XDA, someone talked to a Verizon rep and said it's a VZW bug, not ROM/phone related. This worked for me, here's the fix:
Clear Data on Maps
Clear Data on Google Services Framework
Go to Location Services and turn OFF Verizon Location Services (leave other 2 ON)
Reboot Phone
You should now have GPS lock (hopefully)

If you can get into download mode, you're still OK - you just need to odin via PC. Check the MD5 and filesize of your root66.tar, if it's failing it's most likely a corrupt download. If they match and it still fails, what is the error message that comes up? Once you flash the stock img, get superuser and a custom recovery, and from there I hope you made a nandroid or can clean flash a new ROM. Hope this all helps.

Of course I spoke too soon when I look at the 3 choices under location settings it's missing the Verizon setting it actually only has 2 settings plus 1 location setting toggle at the top which activates the 2 at the bottom it's a different layout.. It's gone back to only working what I toggle it on and off again..
Sent from my SCH-I535 using Tapatalk 2

Hmmmm that sounds like the ROM had changed the menu layout. The problem could be a ROM related issue. Have you checked if its been reported in its specific thread?
Also, go to Google Now (or Google Search), hit menu and go to settings. Check that Google's location services are on.
Lastly, I've heard about and seen better GPS with Wifi turned on, even if you're not connected. Try that too.
Sent via SGS3 using Tapatalk

What worked for me 100% is the app called GPS Status & Toolbox. Worked flawless. I have zero issues and locks solid in less than 20 seconds. That is the longest, usually 5 seconds is normal for me. Program runs when outage GPS enabled and running google maps.

I have tried them..just doesnt work unless i toggle gps on/off..lol..but its strange I can go back to 4.1 and gps works fine... All 4.2 ROMs give me the same issue..the GPS works fine..just doesnt start up on its own when I start maps or something.. I have go toggle GPS..then it works..that goes for any GPS app..just like the one u are talking about..it sounds like your GPS was indeed coming on at least..just weak..my icon doesn't start unless I toggle it after starting GPS app of choice..

Need Help: Can't get 3G

I have posted about this before but nobody was able to help. So I'm trying again.
I can only connect to 4G and 1x. So when I'm in an area that doesn't have 4g I don't connect to 3g but only 1x.
I'm running the Venom rom and I installed the Ota that came out in April.
I have tried switching the network type and it is set to "CDMA and lte/evdo auto".
Can anybody help me with this?

I never heard of this. That is weird for sure. Maybe try an run the RUU an go from there. Just a idea I'm throwing out.

This happened to me. I am using Viper Rom also. Basically when I was in my "home area" 3G/Voice would work great, but when I went out of my home area I had LTE only. So after several factory resets going back to stock without RUU'ing, the only thing that fixed it was RUU'ing. I then reflashed latest Viper Rom and all was good. Don't have any idea why it happened. You might try flashing just the radios from Santod Mods here:
http://forum.xda-developers.com/showthread.php?t=2723159 and see if that fixes it. If not just RUU and you should have 3G again.

First thing I would recommend is flashing stock recovery and doing a factory reset from it. Stock recovery resets some radio parameters that custom recoveries don't

I never heard of this. That is weird for sure. Maybe try an run the RUU an go from there. Just a idea I'm throwing out.

This happened to me. I am using Viper Rom also. Basically when I was in my "home area" 3G/Voice would work great, but when I went out of my home area I had LTE only. So after several factory resets going back to stock without RUU'ing, the only thing that fixed it was RUU'ing. I then reflashed latest Viper Rom and all was good. Don't have any idea why it happened. You might try flashing just the radios from Santod Mods here:
