- Activate a new line with a number you're transferring from another carrier.
- Replace the AT&T number you have now with one you're transferring from another carrier.

- Go to your my AT&T account overview.
- Scroll to My devices. Find the device you want to transfer a number to and select Manage device.
- Choose Options & settings, then Change phone number.
