The company was founded in 1994 by John W. Stanton of the Western Wireless Corporation as VoiceStream Wireless. Deutsche Telekom then gained plurality ownership in 2001 and renamed it after its T-Mobile brand. T-Mobile US provides wireless voice and data services in the United States under the T-Mobile and Metro by T-Mobile brands (the latter was acquired via the purchase of MetroPCS in a reverse takeover in 2013, resulting in T-Mobile going public on the NASDAQ stock exchange), and also serves as the host network for many mobile virtual network operators. The company has annual revenues of around $80 billion.[5]


On April 1, 2020, T-Mobile and Sprint Corporation completed their merger, with T-Mobile now being the sole owner of Sprint, making Sprint an effective subsidiary of T-Mobile until the Sprint brand was officially discontinued on August 2, 2020, with the headquarters becoming T-Mobile offices.[10][11][12] As part of the merger, T-Mobile US acquired Assurance Wireless, the service subsidized by the Lifeline Assistance program of the federal Universal Service Fund.[13]
