To enroll in AT&T AutoPay, you must first either log in to the AT&T app or the AT&T website from your computer or device. From there, you can choose the wireless account for which you would like to set up AutoPay. Then go to Menu, then to Billing and Payments.
In the Billing and Payments section, choose Change Billing and Payment Options, then choose Enroll in AutoPay. You will receive a prompt asking for your form of payment. Once you have entered it, click Continue. AT&T then asks you to make sure that your information is correct. If it is, you can then click Submit.
AutoPay is a service that allows AT&T customers to pay their wireless bills automatically without mailing in payments or submitting their information on the mobile app or website every month. It can take up to one to two billing periods for AutoPay to begin, so continue to pay your bill on time until you see that it has started.
If you need to manage or stop AutoPay for any reason, you can go to the app or website. Go to the section called Manage AutoPay to correct or change any information or to stop AutoPay altogether.
