Here is the info you need:
Thank you for your recent purchase of iPhone 4!
As we prepare to ship devices, we want to make sure that we set your service up the way you want it. Your iPhone 4 has a micro-SIM card that is inside the device. This micro-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 4, 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 4, follow these simple steps when your device arrives and an ATT representative will help you activate.
1. As soon as you receive your new iPhone 4, charge your device fully.
2. Contact AT&T at 1-800-331-0500 or 611 from a different wireless device. At the prompt, enter the wireless number that received the upgrade to iPhone 4.
3. At the next prompt, choose option #2 to activate your phone on a different mobile number, and an AT&T representative will help you from there.
4. After speaking with the AT&T representative, you will be instructed to launch iTunes (
Apple - iTunes) and connect your device.
Please call 1-800-331-0500 or 611 from a wireless phone if you have further questions. We're here to help ensure you have a great experience with your new device.
