NEW YORK (TheStreet) -- T-Mobile US (TMUS) - Get Report shares are gaining by 4.89% to $35.85 on Thursday after the company reported strong fiscal 2015 second quarter earnings results that beat analysts' estimates and increased its subscriber growth outlook for 2015.

For the latest quarter, the company earned 42 cents per share on revenue of $8.18 billion.

Analysts had expected the company to earn 18 cents per share on revenue of $7.94 billion.

In the same period the previous year, the company reported earnings of 48 cents per share on revenue of $7.19 billion.

Additionally, it's the second time this year that the wireless carrier raised its full-year postpaid user addition projections. It now expects to add 3.4 million to 3.9 million postpaid users, up from its previous forecast of 3 million to 3.5 million.

Looking at the company's key user metrics, T-Mobile US added 2.1 million customers in the latest quarter, an increase from 1.5 million customers a year ago. 

This action comes as the company has revamped its pricing plans, got rid of service contracts and has been aggressively marketing campaigns to reverse years of subscriber losses.

However, profits were hurt this recent quarter by the costs involved in these efforts, the company noted.

Separately, TheStreet Ratings team rates T-MOBILE US INC as a Buy with a ratings score of B-. TheStreet Ratings Team has this to say about their recommendation:

"We rate T-MOBILE US INC (TMUS) a BUY. This is driven by a number of strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its impressive record of earnings per share growth, compelling growth in net income, revenue growth, expanding profit margins and solid stock price performance. We feel its strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."
