Q. How can I pay my AT&T bill by phone?
A. You actually have 4 different options to pay by telephone (depending on the capabilities of your phone):
1. For wireless customers, call 800-331-0500 or call 611 from your AT&T cell phone and following the voice prompts to make a payment. If you are an AT&T landline customer or U-Verse customer the phone number is 800-288-2020.
2. Wireless customers can call *PAY (also known as *729) from your AT&T wireless phone and follow the directions to make payment.
3. Pay via the MyAT&T app if you have a smartphone.
4. Use TXT-2-PAY, which only requires you to reply to a text message from AT&T to approve your bill and have it automatically paid using the payment information you’ve set up. You have to enroll in this service here.
