T-Mobile posted 2.4 million net customer additions in the fourth quarter, a record for the Bellevue, Wash.-based wireless carrier.

The company on Wednesday provided a preliminary view of key customer results for the fourth quarter and full-year 2018. T-Mobile reported a record-low quarterly postpaid phone churn of 0.99 percent in Q4 and finished 2018 with 79.7 million customers. It had 7 million total net customer additions in 2018 — that’s up from 5.6 million additions in 2017.

The fourth quarter marked the 23rd straight quarter of net customer additions that exceeded 1 million. T-Mobile has increased its customer base from 46 million in 2013 to nearly 80 million today.

The growth comes as T-Mobile continues to work through its proposed merger with Sprint, a $26 billion deal that would combine the nation’s third and fourth-largest carriers. It gained approved from U.S. national security organizations last month but still has to clear the Federal Communications Commission, which has paused its review due to the government shutdown.

T-Mobile CEO John Legere penned a 2019 predictions post last month, outlining the company’s plans for 5G, T-Mobile TV, and more.

T-Mobile last month announced a 25-year stadium naming rights sponsorship deal with the Seattle Mariners worth a reported $87.5 million.

The company was also included in a Motherboard story this week that showed how T-Mobile, Sprint, and AT&T sell access to customer location data.
