To change the name for any phone listed on your AT&T wireless account, log in to your My Wireless account manager and change the names as listed in your profile. When you change any name in your profile, you are also changing the name that will appear on incoming caller identification screens. There is no charge for changing a user name, and no limit on the number of times a name can be changed.
Log in to your My Wireless account. When the account management screen opens, select "My Profile" in the navigation bar at the top of the page. Your Profile Information page will open.
