AT&T has purchased T-Mobile USA from Deutsche Telekom in a deal which establishes the network as the single biggest carrier in the United States.
The $39bn (£24m) agreement, which is still to be approved by regulators, would see AT&T overhaul Verizon Wireless as the most dominant network stateside with a 43 per cent share of the market.
The deal is the second T-Mobile sell-off German giant Deutsche Telekom has made in the last couple of years, with T-Mobile UK merging with Orange to form the Everything Everywhere network.
Analysts stateside also believe that the deal could push the lower placed Sprint network "into the arms" of Verizon Wireless, lessening the options for the consumer even more.
But the carrier has struggled to keep pace with Verizon's inventory of top Android handsets and better 3G coverage, while it took a further hit when Verizon also gained the rights to sell the iPhone last month.
