Service problems with 3G on T-Mobile

[jkincaid_]

I have an unlocked 3G working on T-Mobile's network.

Lately, it has been acting weird:

Most notably, every time I finish a call it loses service for anywhere between 1-5 minutes. Also, every time it loses service and then gets it back, it notififies me that I have a new voicemail (which is false).

Also, I've called people, only to find out later that they never got the call on their end (and vice-versa). This part is expecially troublesome because of work related reasons.

Anyone ever encountered this?

ask tmobile for a new sim card ($15) or you can do a fresh restore unlock and install the apn and try again
