T-Mobile ends 2015 with 63 million customers, Q4 profit doubles

T-Mobile continues to push its aggressive customer acquisition strategy with the addition of 2.1 million customers to its network and 1.3 million post-paid accounts during its fiscal fourth quarter.

By the end of 2015, the wireless "un-carrier" said its total customer count reached more than 63 million, likely bolstered by its BingeOn video streaming service launched last November.

As for the numbers, the company reported Q4 net income of $297 million, or 34 cents per share, up from $101 million, or 12 cents per share, a year earlier. Total revenue came in at $8.25 billion.

Wall Street expectations were muted by comparison. Analysts were looking for earnings of just 15 cents a share on revenue of $8.20 billion.

For the year, the nation's No. 3 wireless carrier posted net income of $733 million, up from $247 million two years ago. Its shares were up nearly three percent in early trading Wednesday.

"T-Mobile is #1 in postpaid phone growth, #1 in service revenue growth, #1 in Adjusted EBITDA growth, not to mention #1 in customer care and #1 in network speed," said T-Mobile president and CEO John Legere, in a prepared statement. "We set out to change this industry, we're well on our way and we won't stop."

Despite Legere's eternal optimism, it looks like the Bellevue, Washington-based company is bracing for an upcoming slowdown as competition heats up. For 2016, T-Mobile expects to net between 2.4 million to 3.4 million postpaid customers, below the 4.5 million it added last year.
