On Tuesday, AT&T announced its sales results for the second quarter, with the iPhone accounting for 73% of all smartphone sales. During the three-month span, the company managed to sell 3.7 million units, 22% of iPhone users being new to the carrier. In total, AT&T shipped 5.1 million handsets during the quarter. In terms of user base, that translates into 43.1 million of postpaid smartphone subscribers (61.9%), up from last year’s 34.1 million (43.1%).
As suggested by the numbers, the company sold a million more iPhones than its major competitor, Verizon, in the same quarter. Last week, Verizon revealed that its second-quarterly iPhone sales reached 2.7 million units, with smartphone penetration rates of around 50%.
Unlike AT&T, which saw the iPhone lead its smartphone sales, Verizon generates most of its revenue from Android users. Specifically, the carrier sold 2.9 million Android-based handsets last quarter.
During the announcement of its quarterly results, AT&T also revealed that it added a total of 1.3 million wireless net subscribers and saw gains in all user categories. In particular, the company saw 496,000 net tablet and tethering plan activations, resulting in a total of 6.3 million, an over 50% increase year over year.
The carrier also enjoyed the first leap in enterprise revenue in more than four years. While diluted EPS grew from $0.60 in 2011 to $0.66 this year, consolidated revenues climbed up 0.3% to hit $31.6 billion.
“We performed well and posted another strong quarter,” AT&T CEO Randall Stephenson said. “Our wireless margins have never been better.”
