Let's get started
Before you activate your phone:
  • Locate your AT&T phone number on your Order Confirmation slip that came in your shipment.
  • Locate your IMEI and SIM (ICCID) numbers.
  • Transfer your contacts, photos, and videos from your old device to your new device.
  • Use the SIM that came with your new phone to have the best possible experience. If you use another SIM card, you may not be able to utilize some features of your new phone.
Note: Look for your SIM (ICCID) number on your box or SIM card holder.

Now you're ready to activate your phone
