T-Mobile has announced its third quarter results, revealing that the company added a total of 2.3 million customers to its network in the quarter, including branded postpaid net additions of 1.4 million and branded prepaid net additions of 411,000.

"Despite our competitors' best efforts, the Un-carrier revolution made huge advances in the third quarter with record net new customers", said John Legere, President and CEO of T-Mobile. "More proof of the resurgent strength of our brand and the massive momentum behind the Un-carrier consumer movement".

The nation's fourth-largest wireless carrier had 52.9 million subscribers at the end of the quarter, an increase of 2.3 million total customers from the end of the second quarter of 2014 and 10 million total customers over the last 6 quarters. For comparison, the nation's third-largest wireless carrier Sprint had 54.5 million subscribers at the end of June.

The company is now expecting to add somewhere between 4.3 to 4.7 million new net postpaid customers this year, up from its prior forecast of 3 to 3.5 million.

Under Legere, who took the helm of the company about two years ago, T-Mobile has added 20 million new customers, and has also acquired the reputation of being a disruptor of the wireless industry through its "Uncarrier" moves – killing long-term contracts, paying early termination fees for those who switch to its network, free international data roaming, and more.

Although T-Mobile called it the company's best growth quarter, it delivered a lower-than-expected earnings performance, reporting a quarterly loss of $94 million, or 12 cents a share. Market analysts were expecting a profit of 2 cents a share.
