T-Mobile US delivered a strong set of Q2 2015 results, including a 14 per cent jump in revenue to $8.2 billion and net income of $361 million.

This outspoken approach, along with some revamped pricing, has drawn subscribers back to the operator as its vies for third spot in the US with Sprint.

T-Mobile US made 2.1 million net additions in the second quarter, including 1 million postpaid users. And  the operator increased its full-year guidance for postpaid net adds to 3.4 million – 3.9 million, from 3.0 million – 3.5 million.

Subscriber growth lifted revenue in the quarter, including service revenue up by 12 per cent to $6.1 billion.

T-Mobile US also generated net income of $361 million, down from $391 million in the year ago period although the 2014 figure was boosted by a disposal of spectrum that netted $747 million, partially offset by a decrease in income tax expense in Q2 2015. On a sequential basis, the operator was back in the black following a loss of $63 million in Q1 2015.
