T-Mobile US traces its roots to VoiceStream Wireless, the GSM business John W. Stanton built inside Western Wireless in the mid-1990s. VoiceStream was spun off in 1999, bought by Deutsche Telekom in 2001 in a deal valued at roughly $35 billion including Powertel, and rebranded T-Mobile USA in 2002. The 2013 reverse merger with MetroPCS created the publicly traded T-Mobile US, Inc.
