After installing 2.3.4, I no longer have network access over mobile data. I can access the internet over wifi still. Would restoring data from older versions cause this?
Has anyone else had this problem?
**edit**
Changed my apn from custom tethering back to hsdpa and it works now. Sorry.
the guides state you need to reset your apns to default. also - wrong section
Go to Wireless & networks > Mobile networks > Access point names > press Menu and choose "Reset to default". I think this should work. And yeah, wrong section.
I have tried to manually put my carriers APN in on various ICS/JB roms but for some reason when I click 'save'... it doesn't (save).
When I am using CM7 my APN's are there automatically but in the ICS/JB roms we have here it does not put them in automatically and so , although I have phone/text I do not have any data to access the web.
any suggestions?
anyone?
Background: One month ago I rooted and flashed a custom ROM for the first time, I had no problem.
After flashing a few different ROMs, I noticed that my mobile data was acting weird. I could browse the internet and access most internet required apps, but I couldn't download from the play store, watch youtube videos, or get messages from whatsapp messenger.
Problem Today: I just flashed a ROM that I like but now I have NO mobile data at all. I have full bars and my notification bar shows H+ or 3G but data just doesn't work. In the Browser I get this error: "authentication via the proxy server was unsuccessful".
I restored a nandroid backup of stock Touchwiz and data was working again. So I just did a re-flash of the custom ROM and data still doesn't work!
Notes:
- Notification shows data is connected but I can't access the internet.
- Did a restore to stock and data works, re-flashed a custom ROM and data doesn't work.
- Airplane mode isn't on.
- There is no mobile data limit.
- There is nothing in APN settings, there also wasn't anything in stock Touchwiz (but data worked).
- I flashed different modems and they don't work.
- I have tried some APN apps in the play store but they don't work.
- I am on UltimaROM v7.1 // Siyah kernel 1.8.5 // Android 4.1.2
- Wi-fi works.
Please help.
I ended up fixing the problem. So for those of you who might have a similar issue: the problem was with my APN settings. I just had to properly configure it and disable the proxy.

Check your ROM's forum or your kernel's.Maybe it is a common bug and you only have to wait until they fix it.

I didnt see it my bad.
I had custom android 4.2.2 and i reverted to the original 4.1.2 rom. Now mobile data isn't working. The phone was originaly on orange ro now it is on cosmote ro. It worked Before on cosmote with t e original rom and the custom one. I sent an sms and recived setings but it still doesn't work. It says it's activr bot i see no icon in the notification tab.
Any ideea?
Have you tried checking the APN settings?
I have an issue where i flash my phone with SlimROM and then Chrome and Whatsapp is not working on data. Then I realize that the ROM auto select the wrong APN settings. I entered the right APN settings and I have no issue with getting data.
Also check if all the apps are receiving data via wifi first.

Wifi works. I'm wrighting from my phone now. The settings where wrong but changing them is the first thing i tried but i didn't work.
I never had thisproblem before even when i flashed custom roms. It feels like it doesn't activate the net even if it says it does.
Got it. I had the settings for gprs and i needed the ones for broadband.
Hi everyone,
Thanks for your comment. It turns out the ROM was selecting the wrong APN by default. I switch the APN and updated the settings. Now it works like a charm
So I installed Cyanogenmod 12.1 Android 5.1.1 to my Sony Xperia Z2, and after installation my phone wont connect to mobile network. Wifi works, and phonecalls work. There is exclamation mark in the signal icon, and when i connect to wifi it disappears. I didnt find any mistakes in APN. Could it be wrong baseband? Or what could it be?
Maybe internet settings are missing ? go to settings>more> internet settings> download settings for Internet and MMS. (I had the same problem but it is working fine now)

Check APN settings under the Wireless & Networking menu.You’ll find that no APN has been set. You’ll need to choose the one for your mobile operator or worse – manually enter the APN settings.After setting the APN you could need to restart your phone

I have dont that, and No help.. Could it be the baseband version problem? Im trying to install stock rom, test it if it then would work..
Call *#*#4636#*#* to enter phone settings or use this app and select Additional Info
Select Phone information
Set prefered network type to CDMA auto (PRL) and wait until your phone connects to 3G
Change prefered network to LTE/GSM/CDMA auto (PRL) maybe this works? If not I am sorry

The exclamatory means that there is no internet access. Ask your service provider for manual internet settings.

Now i have stock rom ranking,and after i installed the internet settings from mobile network settings, mobile data started running. In cyanogenmod i didnt have that option in settings so I think thats why mobile data didnt work on cyanogenmod.. How can i get cyanogenmod mobiledata working, without the option to install network settings?

I tried the same but still the same result so I have given up on going back to CM and stick to stock.
Try factory resetting the phone
