I used to have Autopay/billing when I had DSL why is my autopay not working now ?

Due to the different structures of DSL and U-verse, the autopay setup you have for one does not automatically transfer to the other. You would have to had it setup by the billing representative on the phone or you can easily do it yourself by logging into your att.com account.

Just login using your email and password at att.com. From there, it usually asks you immediately to sign up for paperless billing. If not, just hover your mouse over Bills&Payments and choose Paperless Billing.
