- 1). Maintain service with your existing landline telephone carrier. You will not be able to port your number without existing service.
- 2). Check with AT&T Wireless for your number transfer eligibility to ensure that you are able to port your existing landline number to their mobile service. They provide a convenient form on their website (see Resources) where you can enter the telephone number and your zip code.
- 3). Initiate the transfer process with AT&T wireless by signing up for an account either in person, over the telephone or over the Internet. You must initiate the process with the receiving carrier, in this case AT&T Wireless, to ensure that your number is properly ported.
- 4). Provide all necessary documentation, signatures and fees. AT&T will request documentation that shows you control the number to be ported, typically in the form of an existing bill. Sign and fax everything required and pay any fees assessed by AT&T for the porting request.
- 5). Wait until your old landline carrier has approved the porting request. AT&T provides a form on their website where you can track the status of your porting request (see Resources).
