T-Mobiles bold new strategy is turning its prospects around. CEO John Legere announced today that Q4 2013 was his companys best quarter in eight years, seeing the addition of 1.645 million customers — a dramatic change from having lost 32,000 customers that quarter the prior year. In total, T-Mobile added 4.4 million new customers in 2013, all on the heels of John Legeres freewheeling press conferences and T-Mobiles network improvements and consumer-friendly changes. With the numbers in, Legere sounds more confident than ever about T-Mobiles ability to change the wireless industrys status quo.
