John Legere, now former CEO of T-Mobile, was supposed to stay in the top job until the end of April, but he has handed over the leadership reins to his longtime second-in-command, former COO Mike Sievert, effective immediately.
Sievert is now officially CEO of the new parent company, which is called T-Mobile. It has about 100 million customers. The company plans to quickly develop the 5G wireless technology that will bring broadband-style service through the air. T-Mobile has said that deploying 5G would have taken much longer and cost much more without the addition of Sprint.
Sievert said the company would start to unify Sprint under the T-Mobile brand this summer.
Legere has led T-Mobile since 2012. He is still on the company’s board of directors, but he’ll be stepping down at the end of his term in June.
