If it is an AT&T phone, you will only be able to use it with Prepaid networks that use the AT&T network. Straight Talk, Cricket, Net 10, etc all use AT&T networks. You won't be able to use it for MetroPCS, Virgin Mobile, Verizon, Sprint, and T-Mobile. For T-Mobile and networks that use T-Mobile's networks, you will have to purchase an unlock code for the phone.
