Default [Q] Can't use mobile data - IP addr not reachable android

Hello, guys.
After I flash the OmniROM (build of 03/12) my device can't connect to internet using mobile data.
I think it's not an EFS problem because the device's IMEI is OK, I can make/receive calls and send/receive SMS. I restored a backup of EFS but the problem persists.
Already flash stock (Jelly Bean and Gingerbread), tried different firmwares and custom ROMs but nothing fixed the problem.

This is a screenshot taken while in Gingerbread, It says "IP addr not reachable android" and "Fail: Host unreachable" after run the ping test.
 


PS: it's not a SIM card problem because I can use mobile data in other devices.

Thanks in advance.
