About T-Mobile
T-Mobile US, Inc. is the second-largest wireless telecommunications provider in the United States, serving approximately 125 million customers across postpaid, prepaid, and wholesale segments. Headquartered in Bellevue, Washington (with a secondary headquarters in Overland Park, Kansas), T-Mobile is a subsidiary of Deutsche Telekom AG, the German telecommunications giant that holds a controlling stake.
The company traces its roots to VoiceStream Wireless, which was acquired by Deutsche Telekom in 2001 and rebranded as T-Mobile USA. Under CEO John Legere (2012–2020), T-Mobile launched its revolutionary “Un-carrier” strategy, eliminating contracts, overage fees, and other consumer pain points that defined the wireless industry. This customer-first approach fueled rapid growth and transformed T-Mobile from a distant fourth-place carrier into a genuine competitor to Verizon and AT&T.
The defining moment came on April 1, 2020, when T-Mobile completed its $26 billion merger with Sprint Corporation, combining the third and fourth-largest U.S. carriers into a strengthened competitor with vast mid-band 5G spectrum. Under Mike Sievert’s leadership, T-Mobile successfully integrated Sprint’s customers and network, built the nation’s largest and fastest 5G network, and expanded into fixed wireless broadband with T-Mobile Home Internet, now serving millions of households in underserved areas.
T-Mobile trades on the NASDAQ under the ticker symbol TMUS and is a component of the S&P 500 index. The company reported over $85 billion in total revenue and $11 billion in net income for fiscal year 2025.
