AT&T promotion cards are prepaid phone cards that you can use anywhere in the world. This allows you to call friends and family while you are traveling without racking up a huge phone bill (for you or for them). However, after a few calls you may wonder how many minutes you lave left in the balance. You can check this out in only a few minutes time and you can even do it from a pay phone.
Look on the back of the AT&T promotion card. Listed in the fine print is a phone number you can call to determine your balance. The number is 1-800-364-9292.
Dial the number on the back of the card. Select the language you want the balance read in.
Punch in the card number you find on the front of the card when prompted. Once you have finished, the available balance on the AT&T promotion card is read out loud.
