Upon initial purchase, record the SIM card phone number and
expiration date to simplify the process. Users may update the
account monthly or pay as many months in advance as you
wish to remain active. Replenishing the AT&T SIM card can be
accomplished in three ways:
1. Visit the local AT&T corporate store in person.
2. Visit a local AT&T Express Service Kiosk.
a. Select- My Payment Options- Prepaid Accounts. b. Enter wireless number then verify wireless number. c. Select- Refill my prepaid account. d. Select the amount to add to your Prepaid Account.
3. Pay by credit card over the phone at 1-800-331-0500.
a. Press 1 for other. b. Press 0 to speak with a customer service representative.
Users must speak to a customer service rep as the SIM card does not have a pin number to use the automated system.
