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.

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 ?

Can't recieve sms/mms while on wifi

So I have cm7 and cwm. I cannot send mms/sms while wifi is enabled. I havent tried calls yet but i will in a second. Just wondering if anyone else has this issue?

Did you do a full wipe and install the rom???

I have a similar problem but opposite from yours. I can only receive SMS/MMS when I'm connected to wifi but I was using cm9/ics rom.

I full wiped about 10 times now and it still hasn't worked. swapped sim cards too but that didn't help.

Redownload the rom...People are having problems with that

Yeah I did everything right! I just reset it and the problem went away. So I'm good now.

I'm telling you it's one of two things, either your Baseband is outdated or APN gets lost. Next time it happens, and it will, check your APN... Settings > Wireless Networks > Mobile Network > Access Point Names... guarantee you it'll be blank. yahtzee. Good luck.

I did check for that when it happened and it actually wasn't. I had a similar issue with the iPhone 4. Unlocking those phones were a pain in the butt. You had apn issues, mms issues, you needed a special sm card, etc. So checking the apn, was a thought that did register initially. Not to undermine what your saying but I don't think I will happen again.

so I've tried full wiping, wiping cache, dalvik cache, downloading and reflashing the rom, checked my baseband which is july 15, checked APN settings which was already set and its still not working. Any other suggestions or was it just not meant to be for my phone -_-

No worries man I hear ya... just making sure you checked that. What ROM are you on and what kernel? You can also use logcat and check for any errors related to Kineto.

Are you on an ICS ROM 4.0.x? If so theres an additional formatting step you need to take. Make a full back up first and I'd even save a copy on to PC just incase (also backup your 'recovery' image in CWM folder). You need to do the usual full wipe stuff, PLUS you need to format /system. Then flash ROM.... Moints and Storage > /format system. Be cautious and read more into this.

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.

im having the same problem here :// i only can get cellNetwork if i restart with airplane mod.. then after i rebooted i go back to normal 3G/2G mode but otherwise i dnt get cell signal// also seems like wifi has some bugs im using HOHO CM7

Having this issue as well after updating to the new Google Play app. Although, I'm unsure of whether it's the apps fault or the fact that I got a new modem. Will be testing with another wi-fi connection today.

Maybe synchronization with your Google account? You could try to go to settings and synch your account or remove it and re-add it. Things like that. If you did everything you could with the app then the account may just be acting up.
I've noticed the Market/Play will tell me an update is available when it's not and randomly the tablet will tell me to log into Google account with no loss on WiFi connectivity. I usually reboot to solve that. Good luck.

are you rooted? i have the same problem when updating apps. it justs hangs there.

problem fixed at last!!!
I finally managed to solve the problem. Just follow these steps, but bear in mind that i'm using a custom ROM so it might be a little different with you. Go to Settings > Wireless and network > Mobile networks > Access Point Names (or APN). Now select the APN that u are using. (I chose MTN Data since i'm MTN. Now go to "Proxy". There should be a number in there, delete everything that's in there and leave that field blank. Go to "Port" and clear everything as well. It worked for me.hope it works for u too. Let me know.

Yeee Peeeee!!!

[Q] Losing data connection

Let me try to explain... Tmob US rooted new HTC one S.. Running trick Droid 4.3..
For some reason I have I will not be able to connect to data. The indicator still says connected sometimes I see the 3g up arrow go solid. Other times it trys to send some stuff on HSPA but does not work.
I have done the research.
I have flashed the latest radio. TMOB one not EU
I have reinstalled rom with full data, cache and dalvik wipes.
I know there is some sort of radio problem from HTC.
But this problems happens a many of times a day and there is no indication when it is broken until you see that there is no notifications and / or you go to use your data connection.
The only fix that I have found that works is to turn the mobile network off then back on....
Stats: 4.03, Baseband 0.16.31501s.16_2_10.22.3150s.10L, Build number 1.78.401.2.cl58751 Kernel 3.0.8-01136.....
What is the best way that someone has found to fix this....
Thanks in advance...

Look in the forum for the fast dormancy fix.
Sent from my HTC One S using XDA

I have tried many things and still have the same problem...
Attempts:
- New Micro sim not one that was cut down.
- New Rom (TrickDroid 6.1) Full wipe, cache, dalvik
- Fast Dormancy comes as a tweak in Trick Droid. Did not help.
- Update the radio to the latest one for tmobile.
Now sometimes I also cannot make a call or get a incoming call.
The fix is to put the phone in airplane mode then turn airplane mode off.
Has anyone else seen this.....
What is a way that I can diagnose / debug....

I would reformat sdcard, maybe even with sdformatter--copy to pc first and have nandroids on pc too
Wipe System 2x if you don't already
Try Axiom or LeeDroid

If all this OP mentioned is done including the ones I listed, there may not be a solution atm--barring return/exchange. I have never had the wifi issues, so not sure why some do and some don't--

Well I am trying everything now..
I will update soon.
I am re-installing TrickDroid 6.1. (Fresh Download) (Tmob version S4)
- Wipe cache, Data, system
- Format sdcard, data, system, cache (This is the first time I have ever formated sdcard)
- Did wipes and formatting more than once.
- Made sure that I format everything...
- Made sure boot.img is correct. by downloading and re-flashing
- New Micro sim from Tmob - NOT one cut down....
- Made sure all data from SD card is gone...
Once I get back up and test it out some more I will let everyone know if it worked...
I am not sure what is the problem... Maybe something was left on the sdcard???
