No data connection, WIFI works OK

[dr_tracker]

Hi guys, I have posted this in XDA, but have not find any answer to the problem so I post it in here to see if you can help me. FYI I'm not located in the US, so I guess all info hereon should be considered for international user.

Last week I got my hands on a second hand Atrix from AT&T, inmediately sim-unlocked it to use my cell provider. Tested all the functionality in stock form, but had no data connection, only got internet connection via WIFI. Unlocked the bootloader and rooted, installed a custom recovery. Everything good so far, but still no data.

Tried CM7, got in a bootloop and went back to stock via a "fruitcake" found in XDA.

Switched to the latest version of Aura, still no data. Found some info regarding the radio versions, first switched to Bell GB radio, tried Orange GB radio and switched back to the AT&T GB radio. All downloaded from XDA and flashed via recovery.

Installed CM7 again, it's working perfectly, again switched through all 3 radios, checked my APN settings, no data. Tested the SIM in my old HTC, it had access, so I guess the network is not the problem.

Please help me, I don't want to get rid of the Atrix because of this issue.

BTW, in my area, my cell provider doesn't have 3G, only EDGE, if that matters.

If you go to settings/battery and data/data delivery, is background data and data enable checked?

Hi RobKort, since I'm on CM7, I don't have those exact settings, but yes, background data (under Accounts and Syncs) and data enable (under Mobile Networks)are both checked.

Any other sugestion???

So you are sure that your APN's are the correct one for your carrier? If that's not it then it has to be something with CM7 which I'm not familiar with. One of the guys here can shine on that further.

Edit/ the only other thing I can think of is the SIM card itself, have you tried reseating it, are you able to make calls?

Thanks RobKort, I inserted a SIM from another company and worked inmediately, including 3G. I will check with Customer Service with my provider to see if they can help.

I'm relieved to know that the cell is working OK.

Glad you figured it out. The unlocked sim card would have been my thought as the primary issue to examine.
