Simple AT&T question! PLEASE answer!?

[Brian]

No. When you are "disconnected" from AT&T meaning their services to your phone is gone. The system within AT&T servers cannot store "dead" or "unused" phones messages, otherwise they would had messages as old as 20 years ago. When you are disconnected, it is if you no longer want to phone to be with AT&T. Therefore the number will be removed from their system. Once you re-apply back to AT&T, your phone number will be back in the servers and working again. However, messages during the time period in which your phone has been disconnected, will not be received. Just twitter or facebook your friends. Or wifi them through google voice.
