T-Mobile added 2.1 million total net additions to its network and one million post-paid accounts during its fiscal second quarter, giving the No. 4 US wireless carrier a major boost as it fights to overtake Sprint for the spot at No. 3.
The company reported a profit of $361 million, or 42 cents a share, down from a profit of $391 million, or 48 cents a share, a year earlier. Revenue grew 14 percent to $8.2 billion.
The carrier's adjusted EBITDA was $1.8 billion, up 25 percent from a year ago.
Wall Street was looking for earnings of 18 cents a share on revenue of $7.94 billion.
In addition, T-Mobile once again upped its subscriber outlook for 2015 and now plans to add 3.4 million to 3.9 million net postpaid subscribers -- up from its previous guidance of three million to 3.5 million.
T-Mobile's Q2 growth could finally be enough to push the carrier past Sprint in terms of subscriber counts. T-Mobile ended the quarter with 58.9 million customers.
While nothing is official until Sprint reports its earnings on August 4, T-Mobile has been unrelenting in its efforts to court new subscribers. On Wednesday T-Mobile said it will offer anyone purchasing an iPhone 6 from now on an upgrade to the next iPhone model at the same locked-in $15 per month price.
Earlier this month the carrier said that it would drop all additional charges for calls and texts to and from Mexico and Canada.
In June T-Mobile rolled out the JUMP! On Demand option, giving customers the option pay a monthly phone payment with the chance to upgrade to a new phone three times a year at no extra cost.
