Razor cell phones can use many networks if they are unlocked, amongst those are AT&T. Motorola, T-Mobile, basically any network you want. Beware however, if the phone is unlocked, it voids the warranty, therefor you will not ba able to get assistance from the manufacturer if the phone encounters problems. If they are not unlocked, they use the Cingular network.
