Our cell phones were turned off for 1/2 a day because of a situation with a stupid internet air card that was on the same account with my cell phones. Anyway, once I got it all straightened out and our phones were turned back on, the voicemail isn't working. My phone just rings and never switches to voicemail. Because it is an iPhone and has visual voicemail, the person at AT&T couldn't help me. Do you have any ideas at all? I went through and set the greeting and passcode, but, it still doesn't go to voicemail. Grr...
