John Legere is already trolling me and we haven't even been on the phone for a minute. "I'm so excited to speak with such a famous reporter," he says. I'm not famous, but Legere, T-Mobile's chief executive, is. Yet before he joined the company in 2012, consumers didn't have a clue who he was. At times, Legere can be alternatively goofy and rebellious, but is able to get away with it because he delivers (he's more than doubled the company's market cap since being hired). Now-commonplace offers from wireless carriersno contracts, unlimited data, upgrade whenever you wantoriginated in T-Mobile's five-year-old "Un-carrier" marketing campaign, which Legere credits with fixing the worst aspects of cellphone plans. We spoke with him to see how much method underpins the madness. Our conversation has been edited.
You made a Claymation Christmas video last December in which you called Verizon and AT&T "bullshit." About two months later, AT&T filed a lawsuit.
When I got the call that AT&T was coming after our Claymation Christmas video, I became so happy. Somehow I just pictured the abominable snowman [depicted as AT&T in the video] having to do a deposition.
