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.

APN // No data
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...
Any clue ?

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.

[Q] Mobile network not working after flashing (ICS)

So, I tried few ROMs and kernels, but every time I had big problem, my network wasn't working.. Not only data, I couldn't make phone calls or send SMS.
Any experience with that?
EDIT: that happened only with ICS roms, now I'm back to GB and it works normally.

Packet data not working on CyanogenMod 10.1 on Samsung Galaxy Ace Plus S7500

Hi, I've been using packet data on my phone (Samsung Galaxy Ace Plus S7500) with stock firmware ever since I go my phone.
I've been trying to install CyanogenMod 10.1 for 3 days, and I can not get packet data to work; I have created the APN as should be for my network provider, but nothing happens; it looks like the phone does not even try connecting to the 3G APN.
Is there anything specifc to be done in order to get packet data working again?

I had seen that post of yours already and I had tried it, in vain. Mine seems to be a different problem altogether; it looks like my phone does not even try connecting through the packet data APN for some reason.
When I'm on that screen (*#*#4636#*#* --> Phone Info), there's a field in there which says "Data Attempts: 0". I even tried accessing the menu on that screen, and there was "Enable data connection", I thought that would do the trick, but nada!
Is there some way I can debug this to see why the phone is not using the Data APN?
Ah, by the way, I have also tried with CM-10, same problem. When I revert back to stock firmware, works perfectly.

As far as i know you are the only 1 i saw who have this problem, others are low connection only. You sure you set your apn correctly? Note your apn setting in stock then flash cm check the apn setting if it is the same on the stock. Or just try to reflash the rom and make sure you follow the installation guide in op.
Try also to consult others maybe they can help.

Well, like I said, after I saw that Packet Data was not working on CM-10.1, I flashed to stock firmware; I created the same APN with the exact same settings as on 10.1, it worked fine; I thought I'd try CM-10 this time, so I did, and I created the same APN again, doesn't work; now I have reinstalled 10.1, with the hope that we come up with a solution soon.
Is there anyway I can see some connection debugging? Using adb, or otherwise? There must be a reason why the phone is not choosing the packet data APN, right?
Edit: I don't know if this could help, but I'm from a tiny island in the Indian Ocean called Mauritius. My operator is Emtel, and you can see the settings for Android on their website (emtel.mu/android). Based on that page, I am supposed to set up the APN as follows:
- For Name, enter WEB
- For APN, enter web
- For APN Type select Internet
- Leave all other entries blank
- Save

On stock firmware, I do have a drop-down to 'Select Internet' for APN type. On CM-10 and CM-10.1 however, I don't have the drop-down; I have only a textfield; could that be a problem?

Ok, so I was able to fix it in a very simple way; I checked out this post (showthread.php?t=2316943), and in there they tell you how to manually modify the /system/etc/apns-conf.xml file; I checked it and went through it, checking how the other APNs were set up; it turns out I just had to change APN Type to "Default" instead of "Internet" as specified on Emtel's website.
It now works!
Thanks for trying to help , ANDROID-000.
Just for clarification; I ended up not needing to modify the /system/etc/apns-conf.xml file manually; I just changed the APN Type from the interface.

No mobile data Connection with correct APN

Hello,
I am using my OnePlus One (64GiB) several days already but today i expierenced a total no data connection. It connects to WiFi and uses the Internet with no problems but if it comes to the mobile data connection it can't connect to the Internet while I have full network shown on the upper right corner. I can call and send SMS with no Problems. This Problem appeared just today and i called my service provider and they say that there is no problem with there network availability and I should check my APN settings which I checked and they are correct. Then the customer consultant said it could be my phone.
I inserted a SIM card from another service provider but it also does not connect to the mobile Internet connection.
So it seems to be that there is some faulty settings on my phone or even an defect. How can I fix that?
Thanks in Advance.

That's strange! It seems like a very random glitch then, which often seem to fix themselves as randomly as they occur.
Have you tried rebooting your device, turning off/on data? Also, in Settings>Mobile Network Settings, is your preferred network type set to LTE, or the highest that's there?

Ok, and the "Data Enabled" checkbox in Mobile Network Settings is checked? And you are positive APN is all correct?
If yes and yes, then I'm not sure what could be the problem, considering how it WAS functioning previously. I would just suggest to keep rebooting and fiddling with the Network settings, such as turning off/on data, verifying APN settings, checking Network Operator, making sure SIM is properly inserted, etc.
I wish I knew exactly what was wrong, but I'm not sure.

I had this problem before. I solved this by doing a factory reset.

A factory reset was my last option. Thank you this did fix it.

Did you resolved? I've same problem. Factory reset didn't work for me!

Hi,
I have the same problem. I only had the phone for three weeks now and two days ago internet stopped working in the middle of browsing/watching you tube video. Did not start since even though I've tried several methods (except factory reset, as I want to leave that one as last resort.
Is there any other way than factory reset to fix it ?

Do you all have franco kernel installed?

Need help
I lost the internet connect when I installed CM12 Nightly -> thought it was a bug in the ROM and sorta lived with it.
But when I reverted to 11-S I realized that the internet connection didn't work on that rom either. I've tried everything factory reset - Soft/Hard - reset -> flash other rom's on it. EVERYTHING!!! -> I also tried a couple of different SIM-cards none of them worked, I tried to contact my ISP, they couldn't help me, they said I had all the right settings so it's most likely something with my phone...
I've got no idea on how I can fix it. and would love if anyone could help me sort this problem out -> I don't have any important data on the phone so we can reset it as much as needed...

I did ask One Plus about it, they send me this zip (re-uploaded) http : // www . mediafire . com / download / rmuaie7f8ch5dji / ONEPLUS % 2BONE - StockRecovery - Windows . zip
(can't post links yet) which I then ran to fix the problem. just be aware of that it locks your bootloader again, if you don't want it to lock your bootloader edit the .bat files and delete the line which says "fastboot oem lock" and you should be good to go (worked anyways for me).

Thanks a ton this really was Helpful.. I guess OnePlus One has a glitch 11.1 and now also with 12.1 CM.. Will try Factory Restore and will update.. Same thing happen with my Frnd in India.. who switch between SP's. He had to restore to fix the internet issue.

I have had the same problem on one of my oneplus 2's. One phone works fine. The other phone was working but is not connecting to Internet using data connection. I have checked the settings and they are exactly the same as the other phone which is working fine.
