AT&T , the No. 2 U.S. wireless carrier, said it will bundle its wireless service with DirecTV's pay-TV offerings after the $48.5 billion deal was approved last month. The combination with DirecTV was aimed at beefing up AT&T's packages of cellular, broadband, TV and fixed-line phone services.

In an offer starting on Aug. 10, AT&T will provide HD and DVR service for up to four TV receivers, unlimited talk and text for four wireless lines, and 10GB of wireless data.

The company said it would serve more than 55 million customers in the United States, Latin America and the Caribbean, making it the world's biggest pay-TV company.
