After about 24 hours of activation, I got through to someone who said the problem was the 1500 text message plan was holding my account. She took it off and put it back on, and boom, activated I can make and recieve calls and its been about 13 hours since I've been activated, however my text messaging won't work. Period. If AT&T sends me one, it doesn't come in. If a friend, it doesn't. When I try to send one it gets about 3/4ths of a progress bar then says "Error Sending Message" My visual voicemail also does nothing. When I click voicemail the button highlights but the screen doesn't change, it won't even dial a number to my voicemail or prompt me to set up. When I dock my iPhone, under Summary where it says Phone number it says N/A. I am an existing AT&T customer for just a few days, I just transfered my number, I should have nothing else on my account so I don't understand. I've called AT&T twice and they've tried things to no avail. Apple couldn't help, I even restored the software but nope. Any ideas?
