The 6+ I pre-ordered from apple.com didn't activate on AT&T either. It was an upgrade for an existing line that was shipped to the billing address of the account. I have not changed any billing info since the account was opened over a decade ago.
The AT&T online activation page tells me:
ACT027: We apologize for the inconvenience but the information you entered does not match our records. Please re-enter your wireless phone number, ZIP code or Tax ID (if applicable) and try again.
Calling in to the automated activation phone number doesn't work either.
The iPhone did activate successfully (shows as activated when I look up its warranty status on apple), but I cannot make phone calls with it, although it does show the AT&T network. When I put in the old SIM, which hasn't been deactivated yet thankfully, it works all right.
