T-Mobile US said late Wednesday that it posted its strongest customer growth in four years, adding 1.1 million customers, including 678,000 for its primary T-Mobile brand.

The company said it now expects to gain between 1 million and 1.2 million T-Mobile brand customers this year.

“T-Mobile’s Un-carrier approach has clearly resonated with consumers,” CEO John Legere said in a statement. “By fixing the things that drive them mad, like contracts and upgrades, and freeing them from the two-year sentences imposed on them by our competitors, they are choosing the new T-Mobile in unprecedented numbers.”

It’s been a time of great change for T-Mobile, which moved in March to do away with phone subsidies and long-term contracts and completed its MetroPCS acquisition in May.

The company said it expects to end the year with between 60 percent and 70 percent of T-Mobile postpaid customers to be on one of the new-style unsubsidized phone plans. About half of such customers are on one of those plans now, up from 36 percent at the end of March.

In recent days, the company has expanded MetroPCS into new markets using the T-Mobile network and launched a promotion where all its phones are available for no upfront cost.

Also in July the company announced its JUMP program that lets customers who pay $10 per month upgrade their phone as often as twice per year.
