Visual Voicemail doesn't work
"Welcome to AT&T Voicemail, we need more information to direct your call to the appropriate voice mailbox. To leave a message, please dial the 10-digit phone number of the person you are trying to call. If you have a mailbox in this system, please press pound."
Any help? I don't know my mailbox number, my phone number won't work.
If i call my phone and go to voicemail, the message i get is: "I'm sorry, but the person you called has a voice mailbox that has not been set up yet, Good bye."
