Investors are happy with T-Mobile right now, after the company posted a better-than-expected Q2 earnings report on Thursday.

tmobileThe quarter included continued customer growth of 2.1 million, 14 percent revenue growth to $8.2 billion and an overall profit of $361 million. That brought earnings per share to 42 cents, up from the 18 cents analysts expected.

T-Mobile selling more devices with equipment revenues up 20 percent, charging customers a record high average of $63.29 per bill and picking up phone subscribers about twice as fast as the competition.

The company also raised its predictions for 2015 subscriber growth by about 400,000 to between 3.4 and 3.9 million.

It was an overwhelmingly positive report, and T-Mobile was rewarded for it when its stock price climbed nearly 4 percent after the report was released.

“Overall, I think our results speak for themselves,” T-Mobile CEO John Legere said in the release.

But T-Mobile does have a financial Achilles heel: consistency on the bottom line.

The $361 million profit the company showed this quarter was up from a loss in Q1, but down from $391 million at this time last year. It’s indicative of the rollercoaster investors have been riding as the company swings back and forth between profits and losses virtually every three months.

T-Mobile still hasn’t posted two consecutive profitable quarters in three years.

The company calls itself the “fastest growing wireless company in America,” and a lot of that success is due to the “un-carrier” campaign and its steady flow of unique promotions. All that price cutting may be boosting the company’s key metrics, but we have yet to see if it can consistently do the same for the one that counts the most.
