Thirds-quarter earnings for U.S. telecom T-Mobile beat Wall Street's expectations, pushing share prices higher in pre-market trading.

The fourth-largest U.S. mobile provider added more than 1 million customers over the quarter contributing to revenue of $6.69 billion, 9% higher than a year earlier. Analysts surveyed by Yahoo! Finance had expected $6.57 billion in revenue. Of the customers added, 643,000 were branded postpaid phone customers, a 64% increase on the same quarter 2012.

The company said strong subscriber growth and better-than-expected revenue is a result of its successful 'Un-carrier' strategy, which aims to present the brand as a customer-friendly alternative to rivals Verizon (VZ) and AT&T (T).

"We are fixing the things that drive customers crazy," said CEO John Legere in a statement. "Our momentum is great and we have confidence that we can continue to deliver sustainable and profitable growth."

Shares jumped 3.6% to $29.35 in pre-market trading. Year to date, the stock has climbed 71.6%.
