T-Mobile US, Inc. is a leading wireless telecommunications provider offering voice, messaging, and data services to consumers and businesses across the United States, Puerto Rico and the U.S. Virgin Islands. The company’s portfolio includes postpaid and prepaid mobile plans, 5G and 4G LTE network access, home broadband solutions and connected devices. In addition to standard voice and data offerings, T-Mobile provides Internet of Things (IoT) connectivity, enterprise mobility management and wholesale services for smaller carriers and resellers.
The origins of T-Mobile US date back to 1994 when VoiceStream Wireless launched as an independent carrier. In 2001, VoiceStream became part of Deutsche Telekom and rebranded as T-Mobile USA in 2003. The company bolstered its national footprint through strategic transactions, including the acquisition of MetroPCS in 2013, which expanded its prepaid customer base. In April 2020, T-Mobile completed a high-profile merger with Sprint Corporation, creating one of the largest wireless networks in the country and accelerating its 5G deployment.
Headquartered in Bellevue, Washington, T-Mobile has focused on network innovation and customer service differentiation, launching initiatives such as “Un-carrier” promotions to eliminate contracts and simplify pricing. Under the leadership of CEO Mike Sievert, who assumed the role in 2020, the company has prioritized expanding 5G coverage, improving network performance and exploring new growth avenues such as home Internet and business solutions. T-Mobile’s management team continues to emphasize customer experience, technological advancement and competitive pricing as key pillars of its strategy.
