T-Mobile, the No. 4 US wireless operator, posted quarterly profit and revenue that handily beat market estimates as aggressive discounts helped it add more than 2 million subscribers.

Shares of T-Mobile US, which has turned around years of subscriber losses, rose 2.7 percent to $31.85.

T-Mobile, two-thirds of which is owned by Deutsche Telekom, offers innovative plans for equipment installation, free international data roaming, and lifetime free data for tablets.

The company, which calls itself the “Un-carrier,” has eliminated contracts and introduced a billing plan that allows customers to pay for devices in installments.

T-Mobile CEO John Legere said also Thursday that a combination with Dish Network could be a good match because of the satellite-TV provider’s video technology and massive cache of airwaves.

Revenue for the quarter jumped 19.4 percent to $8.15 billion.
