T-Mobile US (NASDAQ:TMUS) is a leading wireless network operator in the United States, providing a broad range of mobile communication products and services to consumer and business customers. Operating under the “T-Mobile” brand, the company offers postpaid and prepaid voice and data services, as well as device financing, Internet of Things (IoT) solutions and wholesale network access. T-Mobile’s network portfolio includes advanced 5G, 4G LTE and legacy technologies, delivering nationwide coverage and enhanced connectivity in Puerto Rico and the U.S. Virgin Islands.
Founded in 1994 as VoiceStream Wireless PCS, the company was acquired by Deutsche Telekom in 2001 and rebranded as T-Mobile USA in 2002. Under the leadership of former CEO John Legere, the company adopted its “Un-carrier” strategy in 2013, reducing customer pain points through no-contract plans, simplified pricing and other customer-focused initiatives. In April 2020, Mike Sievert succeeded Legere as CEO, continuing to drive network expansion, customer growth and technological innovation.
In 2020, T-Mobile completed its merger with Sprint Corporation, solidifying its position as the nation’s third-largest wireless carrier. The integration combined spectrum assets and infrastructure, accelerating the rollout of a combined 5G network. T-Mobile for Business serves enterprises of all sizes with tailored mobility, network security and cloud-based solutions, while T-Mobile Home Internet extends broadband services to residential customers through fixed-wireless access.
Headquartered in Bellevue, Washington, T-Mobile US maintains research and development centers, network operations facilities and retail stores nationwide. The company collaborates with device manufacturers, technology vendors and government agencies to advance next-generation network capabilities, including network slicing, edge computing and private LTE/5G offerings. Under Sievert’s leadership, T-Mobile continues to focus on customer satisfaction, network quality and sustainable growth in the highly competitive U.S. wireless market.
