Your AT&T MEdia ID is your personal username across all of AT&T's services sites, including MEdia Net (formerly My Wireless Window) and rucingular. (If you manage your account online, you'll log in with your wireless number and the same password you use here.)
If you have previously registered at My Wireless Window, use your existing username as your AT&T MEdia ID for any of our service sites. There is no need to re-register.
If you have not yet registered with any of AT&T's sites, establish your AT&T MEdia ID now and enjoy all of these sites with one convenient ID and password.
