About the operator

T-Mobile US, Inc. is an American wireless network operator headquartered in Bellevue, Washington, and a majority-owned subsidiary of the German telecommunications group Deutsche Telekom AG (Bonn), which holds roughly 53% of the company. Its roots trace to VoiceStream Wireless, founded in 1994 and rebranded under the global T-Mobile brand after Deutsche Telekom’s acquisition; the present-day public company took shape through its 2013 merger with MetroPCS. A defining moment came on 1 April 2020, when T-Mobile completed its merger with Sprint, retiring the Sprint brand later that year and absorbing Sprint’s valuable 2.5 GHz mid-band spectrum.

Since 2013, T-Mobile has built its identity around the “Un-carrier” strategy — consumer-friendly moves such as eliminating long-term contracts, overage charges and certain roaming fees. It is one of the three dominant carriers in the United States alongside Verizon and AT&T, serving roughly 140 million connections as of late 2025, and also covers US territories including Puerto Rico and the US Virgin Islands.

Network & technology

T-Mobile runs a nationwide 4G LTE and 5G network, having shut down its legacy 3G UMTS service in July 2022. Its 5G combines wide-reaching 600 MHz low-band (“Extended Range”) with faster 2.5 GHz mid-band (“Ultra Capacity”) 5G, which the company says reaches more than 300 million people. Independent testers have repeatedly recognised it — Ookla named T-Mobile the fastest US mobile network in 2024 and Opensignal has rated it the most-available 5G for several years — though Verizon and AT&T have led some rural and overall categories in RootMetrics testing.

Reputation & market position

T-Mobile is one of the three dominant US carriers and the industry’s fastest-growing, holding roughly 35% market share and ranking second only to Verizon in total subscribers as of 2025. It enjoys strong third-party recognition for 5G speed and availability, but its rural and remote coverage has historically trailed Verizon and AT&T. The company’s reputation has also been weighed down by a series of data breaches since 2015, including a major 2021 incident that led to a $350 million class-action settlement.
