After the change, your next wireless bill will have a new account number. It may also have a new due date or a one-time partial-month charge. You’ll have to:
- Set up AutoPay or paperless billing again for each bill. To sign up, go to att.com/autopay.
- Sign up your new wireless account for myAT&T. Go to att.com/myatt.
Good to know: The change will take up to 2 bill periods. Until then, be sure to pay your bill in full. Otherwise, late fees may apply to any unpaid amount.
