T-Mobile US said it added a net 1.9 million new customers in the fourth quarter of 2017 taking its total base to nearly 72.6 million at year-end. Over the full year, the mobile operator gained more than 5 million new customers for the fourth consecutive year. After meeting its FY guidance the company said its majority shareholder Deutsche Telekom is considering buying more shares in the US operator.
However, this was below 1.2 million total branded postpaid net additions recorded in the fourth quarter of 2016. Branded postpaid phone churn was 1.18 percent in the fourth quarter down from 1.23 percent in the previous quarter. The company also said it added total 5.7 million net additions in 2017. Analysts on average were expecting 5.2 million additions in 2017 according to Thomson.
Branded postpaid phone net customer additions were 891,000 in the fourth quarter of 2017. This is expected to be the sixteenth consecutive quarter in which T-Mobile has led the industry in branded postpaid phone net customer additions. For full-year 2017 we added over 3.6 million branded postpaid net customers coming in at the top of the revised guidance range for branded postpaid net customer additions of 3.3 to 3.6 million.
Mobile also added 149,000 new prepaid customers in Q4 and 855,000 in the full year led by its MetroPCS brand. The company said prepaid growth was held back by customer migrations to postpaid which reduced prepaid net customer additions by around 180,000 in the fourth quarter and 700,000 for full-year 2017. Wholesale net customer additions were 633,000 in the fourth quarter of 2017 and 1.2 million for the full year 2017.
