Addituinal notes: When setting up AT&T prepaid, at one point you need to insert the SIM into your handset in order to receive a confirmation code (your login password).
I know this process works while the handset is in Canada. Even though service is not yet activated on this SIM, the SIM can still receive SMS from AT&T via the Rogers network. I *assume* this would work from other countries as well but can't garantee. Rogers and AT&T tend to have fairly compatible and very "connected" systems for roaming as AT&T Wireless(original company) used to own a big chunk of Rogers Wireless. (this step is required for you to login to your new account, deposit funds via credit card and choose your package).
