AT&T Wireless launched free unlimited mobile-to-mobile calling

AT&T announced that starting Feb. 6 will offer unlimited domestic mobile-to-mobile calls at no charge to any of the company's nearly 22 million customers. New customers automatically receive free, unlimited calling from their mobile-to-mobile calling area when they sign a two-year contract for qualifying calling plans of $39.99 or more. In addition, current customers can request the new offer if they are already on such a plan, or upgrade to one, and renew their contract for two years.
