AT&T enjoyed a strong holiday season, selling 10 million smartphones in the fourth quarter. That topped the record 9.4 million units sold in the year-earlier period. The carrier also had its best ever quarter for Android phone and iPhone sales.

“We had another incredible quarter of smartphone sales as the mobile Internet continues to drive strong growth in wireless,” said Ralph de la Vega, head of AT&T Mobility, in a statement. “These are the industry’s most valuable postpaid subscribers with average revenues twice that of non-smartphone subscribers.

He added the company sold an average of 110,000 smartphones a day, and even gave a nod to Windows phones as part of its device portfolio. Despite the launch of Windows 8phones, the Microsoft mobile operating system had only a 3% share of the U.S. market through November, according to the latest comScore data.

Verizon CEO Lowell McAdam yesterday suggested AT&T’s chief rival had a good fourth quarter as well, noting the company added 2.1 million net subscribers. Verizon will announce full-fourth quarter results on Jan. 22, and AT&T on Jan. 24.
