Droid Bionic on AT&T or T-Mobile

[etradetro]

Hello Johnny, I follow the instructions and it works with an AT&T Sim but will NOT work with Tmobile Sim. It says no service. Can you please help on this? I'm anxious to get it working for Tmobile. Thanks so much! I posted the same question in your youtube video as well. Thanks!
