It's not limited to being in your calling area. It's limited to being in an area where AT&T offers service. You couldn't take it to England and use it there, for example.
Personally, I like T-mobile's approach: build the capability into the phone to make calls over any wifi network that can connect to T-mobile's VOIP servers.
