Each package has an expiration time: 30 days for the $15 package, 90 days for the $25, $50, and $75 packages, and 365 days for the $100 package

If you do not refill your account for 60 days after your last airtime expires, then your account will be deactivated and your phone number may be lost if it becomes recycled.

So, go to a ATT/Go phone retailer and add more money to the Go Phone. If your number has been recycled, then you will just get a new number and start talking again.
Good luck,
