HELP: Unlocked BB but T-mobile service won't work

[kheer94]

Hey, so I have a Verizon Blackberry Bold that I recently unlocked, set the the t-mobile service on it, and changed my number on it too but the service won't actually work. The phone shows me having connection, but when I make a call there's always something saying "your call cannot be made" or when I try to go on the browser or any other web-related app it says "your current service plan does not support this..."

The sim card works fine on my old blackberry curve, though. So I'm not sure what I'm doing wrong...

Can anyone help?

Sounds like you do not have the right data plan. Call customer service to register the phone on a BB data plan.

Did you switch it to 2G in mobile network options under manage connections?
