AT&T customers can now make unlimited calls from their wireless phone to any domestic AT&T number, be it wireline or wireless. This change only applies to AT&T’s Unity plan, which is a converged wireless and wireline service. Subscribers’ Anytime minutes are not deducted when calls are placed to any AT&T line, and subscribers can keep their Rollover Minutes for 12 months. The plan also includes unlimited night and weekend minutes. AT&T estimates that it has more than 100 million phone numbers.
