AT&T Unity Plan

Now that AT&T has merged with Cingular Wireless and BellSouth, a new incentive plan for customers to use AT&T for all communications has emerged. AT&T residential phone service customers who also become wireless service customers can call any AT&T phone number for free, with no minute usage. This is the first time the concept of in-network free calling has extended to wired phones. It is expected to reduce costs for many customers struggling under high cell phone bills.

This service starts at $59.95/month on the wireless side and has different terms based on where you are located geographically.
