I have an unlocked Nokia 3595 that I'd like to begin using on the T-Mobile network. I purchased a T-Mobile prepaid
sim card and put it in the phone...but it never shows that I have service[i.e. I can't make any calls]. Even in places where I have previously gotten reception with this phone when it was using AT&T it still shows no service[even in places that people I know with T-Mobile get perfect service!]. Any help or advice anyone can give me would be GREATLY appreciated! Thanks!
