Since this thread has so many pages, I sifted through several of them to find an answer but came out fruitless.

Is anyone else experiencing issues when using a T-Mobile SIM? I have the Verizon Touch Pro2 and switched to T-Mobile and my phone was SIM unlocked and all that jazz. It was working fine on the Verizon stock ROM and it worked even better until recently on the Energy ROM. As of the past two or three builds, I would go to make a call and it tells me to check the number and that it can't be called. Also, the data connection will not work at all either. The only way to get everything up and running again is to soft reset or switch to airplane mode and switch back again.

I've been dealing with it for the past few days but after missing several calls, I had to sadly go back to the Verizon MR2

Any ideas?
