AT&T plan to buy T-Moble USA to make it the Largest US cellphone company

AT&T plans to buy T-Mobile USA for $39 billion Monday and this deal would make it the largest US cellphone company.

AT&T will buy T-Mobile USA from Deutsche Telekom AG in a cash-and-stock deal that would decrease the number of wireless carriers with national coverage from four to three, the Star Tribune reported.

Forrester Research analyst Charles Golvin told NPR that if the deal goes through, consumers would benefit from improved quality and coverage with high-speed broadband services, the NPR reported.

"We know the results of the arrangements like this--higher prices, fewer choices, less innovation," Public Knowledge president Gigi Sohn said in a statement, the Star Tribune reported.
