You tried updating the roaming capabilities?

Sounds like you're on OS .328 (or earlier OS 5.xxx), am I right? .328 doesn't work with T-Mo...you either need to go backwards to a 4.7 OS or update to the MTS Mobility 5.0.0.419 release. That will fix your problem.

Oh yeah, this has been WELL covered here, so search around, especially in the OS section.

The .328 worked fine for me on tmo. The .419 has some flaws but nothing a quick battery pull cant help.

Diod you check the sticky threads at the top of the Forum? I believe 1 of them deals with using the Storm on other carriers.
