TL;DR Mike Sievert will step down as T-Mobile CEO on November 1, transitioning to the role of vice chairman after five years of leadership. T-Mobile’s current COO, Srini Gopalan, will assume the CEO role. T-Mobile will soon have a new CEO, but is this a good or bad sign? Customer service reps will be increasingly pushy and more likely to talk you into features you don’t need, in order to meet their aggressive sales goals. Can this be done without T-Mobile’s customer service quality taking a notable downward hike?
