You'd probably need the phone "unlocking", there are loads of people who can do this - look for smaller phone shops / stalls that advertise "unlocking" and ask them (how much?) before you buy.

If you can, it'll be on the standard account already assocated with that T-Moble sim card, on T-Mobile's network.... which leaves me wondering why you would want to get the phone from AT&T.
