So i recently unlocked my phone, as am in Europe and now, with two different carriers all I've been able to receive is edge on the network. My imei code is still there when i do *#06# and I don't know if I messed my phone up because I cannot test it on T-mobile's network. Any clue one how to fix? The phone is currently running Stock 4.1.2 with root, because I downgraded to unlock. Any help is greatly appreciated.
