If u hardly use the phone, maybe you can lower your usage plan to one thats more fitting. With Cingular if you are out of contract there is no extra monthly fee. If u took your phone to them now you could have it activated with no contract. Or you could call up customer support and they would hook you up too. Maybe if you didnt cancel it too long ago they could reuse your original number. Im not sure if they sale prepaid
sim cards in the states yet, if they do u could get one from any other provider and install it in your phone. The only downfall to this would be that you would have to have your phone unlocked. Someone PLEASE correct me on this.
