Can I use a different Provider with ATT nokia 8260?

Hi, I think this is called a cdma phone? I recently aquired a used nokia att phone from a non-profit charity I volunteer at, and would like to know if I can use it with my cricket service, neither phones use sim cards. Any assistance would be very much appreciated thank you.

Actually, the 8260 is not a CDMA phone, but rather TDMA. Hence, you won't be able to use it on Cricket, as the only service provider that still uses TDMA is AT&T they've stopped adding new customers to that. Nextel uses TDMA too, but a modified one, so that won't help you either...
