About
T-Mobile is the second-largest wireless carrier in the United States, founded in 1994 and headquartered in Bellevue, Washington. The company transformed its competitive position through the "Un-carrier" strategy launched under CEO John Legere in 2013, dismantling the industry's most frustrating practices — two-year contracts, data throttling, international roaming fees — and forcing the broader industry to follow. T-Mobile's core technology advantage is its nationwide 5G network, which it built faster and more broadly than AT&T and Verizon by leveraging mid-band spectrum acquired through its 2020 merger with Sprint.\n\nT-Mobile serves consumers, businesses, and enterprise customers across its namesake T-Mobile brand and prepaid brands Metro by T-Mobile and Mint Mobile (acquired 2023). Its 5G network covers 300 million+ people with the industry's most extensive mid-band coverage, delivering the combination of broad reach and fast speeds that defines 5G's practical value for consumers and businesses. T-Mobile has been the industry's consistent leader in postpaid net customer additions, a key indicator of competitive health in a near-saturated wireless market.\n\nT-Mobile reached 140 million subscribers in September 2025 and led the industry with 903,000 postpaid phone net adds in Q4 2024, generating $17.4B in service revenue in Q2 2025. The company has expanded beyond core wireless into home broadband (T-Mobile Home Internet), now one of the fastest-growing broadband providers in the US, and enterprise 5G services. As the wireless market matures, T-Mobile's combination of network leadership, disruptive pricing culture, and broadband expansion positions it as the most offensively positioned of the three major US carriers.
