You activate a new iPhone and establish service by connecting it to a computer and iTunes. You cannot activate and establish service over the air - you must use iTunes via a cable connection to your computer.
Once activated, you should be able to establish service with AT&T over wifi.
P.S. you can also call AT&T from another phone and they can walk you through the service setup in a couple of minutes.

Thanks for your reply. I have an old iPhone but it can't create a hub. (I'm on my iPhone right now.) I'm trying to connect my iPad (has 3G) to cellular but I don't have access to wifi right now. I' used 3G on my iPad quite awhile ago and had had an AT&T account. It sounds like I have to be connected to at least wifi to deactivate my iPad 3G access.

Yes, you can do it over wifi, but your phone is not going to connect to AT&T's cellular network at all until you've established service on it.
If there is an AT&T store nearby, just walk in and ask them to do it (have your account info handy).
