Hi, does any one know that what is AT&T voicemail number for cell phone? I mean what do you dial to listen or edit your voicemail on AT&T. When I go into my phone Settings > Services > Voice Mail and Text Messages. The numbers there are weird the voicemail is that (772) and the Text messages Service center is a weird (312) number. Can someone tell me what is the AT&T voicemail number for cell phone? I am waiting for your answer.
