NEW YORK ( TheStreet) -- Telecommunications giant AT&T's ( T) third-quarter earnings met the estimates of analysts as it added 2.1 million wireless subscribers to pass 100 million.

AT&T earned $3.6 billion, or 61 cents a share. Revenue fell 0.3% to $31.48 billion.

Analysts surveyed by Thomson Reuters expected AT&T to earn 61 cents a share on revenue of $31.62 billion.

"Smartphones, connected devices and tablets all posted impressive gains," said Randall Stephenson, AT&T chairman and CEO, in a press release Thursday. "Our first LTE 4G markets are up and running with terrific speeds. And we continue to work toward a successful completion of our planned T-Mobile USA merger.

"The next waves in the mobile Internet revolution represent tremendous growth potential, and we are laying the groundwork required for that future," he said.

AT&T said Thursday it activated 2.7 million iPhones in the third quarter, the lowest number in a year and a half.

The company gained a net 389,000 subscribers on contract plans in the quarter, roughly in line with analysts' expectations and higher than subscriber gains of 62,000 in the first quarter.
