The second largest U.S wireless carrier, with this record sale, is trying to bounce back from its third quarter set back, when the company could add only 151,000 contract subscribers into its quarter sale.

“We had another incredible quarter of smartphone sales as the mobile Internet continues to drive strong growth in wireless,” AT&T Inc. (NYSE:T) Mobility CEO Ralph de la Vega said in a statement.

The leading wireless carrier marked this record sale as the best ever quarterly sales of both Android and Apple Inc. (NASDAQ:AAPL) smartphones.

“These are the industry’s most valuable postpaid subscribers with average revenues twice that of non-smartphone subscribers. During the quarter, we averaged more than 110,000 smartphone sales a day as customers flocked to our leading portfolio of the latest Android, Apple Inc. (NASDAQ:AAPL) and Windows devices. Combine that with the nation’s largest 4G network and lightning-fast LTE network that now reaches more than 170 million people and you’ll understand why customers continue to choose AT&T Inc. (NYSE:T) in record numbers.” remarks Ralph in his statement.

Catching up with its industry rival Verizon Wireless, who also recorded a historic sale by adding 2.1 million net subscribers in its fourth quarter, AT&T Inc. (NYSE:T) is rolling out a network using a technology called long-term evolution, which allows for faster downloads.

According to Ralph de le Vega, the company aims to focus more on gaining more smartphone subscribers. Smartphones subscribers bring twice as much revenue as any other customer who buys and owns a simple mobile phone.

Interestingly, the fourth quarter was marked as the best quarter by Verizon Communications Inc. (NYSE:VZ) Wireless as well.

Both companies plan to report their forth quarter results on January 24.
