[Q] AT&T to AIO issues with mobile data
I am having some issues making the switch and needed some help.
I purchased my Galaxy S2 from AT&T awhile back, rooted and installed task650's AOKP rom after I had issues with the ICS update, and have been running the latest build happily ever since with no problems. After my contract was up I got an unlock code from AT&T, purchased a sim from AIO and installed it. The phone booted up and never asked for the unlock code. I am able to make and receive calls and texts, but mobile data doesn't work. WiFi works just fine. I installed and ran GalaxSimUnlock and Galaxy S Unlock. Both programs indicated my phone was unlocked.
Is this an issue with AIO? The signal bars say AT&T on the phone, but I just assumed since AT&T owns AIO this was normal. Do I need to install a different rom and try to unlock again? I am going to try and track down a sim from a different carrier and see if that works. I have tried dialing *#7465625# to check the unlock status, but it returns the error "connection problem or invalid mmi code".
I have searched for answers, but I am clueless. Any help would be appreciated. Thanks!
