Thanks to its "no device subsidy" model, AT&T says it lost fewer customers to rivals than it ever has in the first three months of the year.
Most of AT&T's customer gains in the fourth quarter came from its non-smartphone business.
The carrier, meanwhile, says it's brought LTE to 41 more cities, and its Sprint Spark enhanced network to another six cities, as it trudges through its painful network upgrade.
The Uncarrier march continues to pick up steam, but the growth is coming at a cost as the wireless carrier posts another loss because of its aggressive promotions.
The name of the game is spectrum, and the carriers are jockeying for rules that could determine the ultimate winners and losers of the wireless wars.
The company may get rid of the unlimited data plan altogether in the future, says the CEO of Sprint.
Verizon CFO Fran Shammo says the carrier won't be following AT&T and T-Mobile's lead.
The offers come after the company posted fourth-quarter results that showed a spike in customer defections.
The carrier lost $2.38 billion in the quarter thanks to charges related to its wireline assets and its brand.
There's no better way to make a good impression than with a memorable Super Bowl ad, and the two carriers figure to make headway against bigger spenders Verizon Wireless and AT&T.
