AT&T Sells Record Number of Smart Phones in 4Q 2012

AT&T Wireless sold a record number of smart phones in the fourth quarter of 2012, selling 10.2 million devices, which AT&T says is the most ever sold by any U.S. service provider in a single quarter. In fact, 89 percent of postpaid phone sales were of smart phones. 

AT&T also reported that wireless revenues grew 5.7 percent year over year, while wireless service revenues grew 4.2 percent.

AT&T had 780,000 wireless postpaid net adds, the largest increase in three years; with a 1.1 million increase in total net wireless subscribers. 

But that growth also came at a price. Since AT&T subsidizes smart phones, and since so many customers purchased Apple iPhones that have the highest subsidy costs in the business, earnings took a hit. In fact, 84 percent of all smart phone sales were iPhones. 

Verizon, for its part, added a "highest-ever" 2.1 million net new wireless contract customers in the fourth quarter, outpacing AT&T's growth. 

As expected, Verizon profit margins on mobile services dropped as smart phone subsidies grew. 

And that is an issue: though service providers want to sell more data subscriptions, which mainly entails selling more smart phones, the device subsidies are a drag on earnings.
