As we prepare to ship devices, we want to make sure that we set your service up the way you want it. iPhone 5 comes with a nano SIM card pre-installed. This nano SIM will be activated to the upgrade eligible phone number that you used to place your order. If that is the same phone number you plan to use with your iPhone, you are all set. Just follow the step-by-step activation instructions that arrive with your shipment.
However, if the number you used to order your device is NOT the number you intend to use with your iPhone, follow these simple steps when your device arrives and an AT&T representative will help you activate.
Please call 1-800-331-0500 or 611 from a wireless phone if you have additional questions. We're here to help ensure you have a great experience with your iPhone.
