When you upgrade your phone on Cingula/AT&T do they put a new SIM card or Chrge for Activation?

Answer 1

If you already have Cingular (A T&T) and plan to upgrade your phone, all you have to do is to purchase the new phone and use the sim card from the back of your old phone and put it into the new phone. There should be no activation charges.

Remember if you are already a Cingular customer and plan on upgrading your phone you might be required to sign or renew a 2 year contract.
