SIM size and activation date?

If you order a SIM with a prepay plan, what size SIM is provided?

And...

How are the 30 day prepaid plans activated? Is it when the SIM is placed in the phone?

AT&T SIM cards are multi size, punch out, so will fit nano or larger.  If you have a phone that does not use a nano SIM there's a good chance it's not capable of working on AT&T. If you are bringing your own device always check the IMEI

The activation process occurs when your SIM card is installed in your phone. Following the prompts to select a plan, set up your online prepaid account with an alphanumeric password and PIN code. Only then will you be required to pay for service.

If you order the $300 plan online, please have your order number saved to activate that plan.

Thanks, but the prepaid options are paid before ATT sends the card, not when you put in a SIM - so I wanted to know if the 30 days prepay only activates once you put the SIM in the phone.

Also when ordering the prepaid and card, ATT is asking for a current phone number. I live internationally so that's not possible and I don't understand if I give someone else's if it would try to recognize that number on the phone when I put i the SIM card.
