T-Mobile delivered standout results in the first quarter of 2026 by adding more than 500,000 net broadband customers, reinforcing its status as the fastest-growing internet service provider in the United States. The performance was driven primarily by accelerating growth in its fiber and 5G Home Internet service, the fixed wireless access offering that delivers high-speed connectivity without the need for traditional wired infrastructure. This marked another quarter of robust expansion for the 5G-powered home broadband segment, which has become a cornerstone of the company’s diversification beyond mobile services. This comes as both Comcast and Spectrum lost internet customers at the same time.
The 5G Home Internet additions contributed significantly to the overall broadband tally, building on momentum from prior periods where the service consistently captured the largest share of industry net gains. T-Mobile’s approach leverages its expansive 5G network to reach tens of millions of households, particularly in suburban, rural, and smaller markets where cable and fiber options remain limited or expensive. Customers benefit from straightforward setup, unlimited data plans with no annual contracts, and competitive pricing that often bundles seamlessly with mobile lines. This accessibility has helped the carrier attract new households while deepening relationships with existing wireless subscribers.
Broader financial results underscored the strength of this broadband push. The company recorded 217,000 postpaid net account additions during the quarter, representing a 6 percent increase from the same period a year earlier. Service revenues climbed to $18.8 billion, an 11 percent rise year-over-year, while core adjusted EBITDA grew 12 percent to $9.24 billion. Postpaid average revenue per account reached $151.93, up 3.9 percent, reflecting the successful upselling of higher-value services, including home internet bundles. Management responded by raising full-year guidance for postpaid net account additions, core adjusted EBITDA, and free cash flow, signaling confidence in sustained momentum across consumer and business segments.
T-Mobile’s 5G Home Internet stands out for its performance metrics. Independent testing shows median download speeds more than 50 percent faster than the nearest fixed wireless competitor, enabling reliable streaming, gaming, and remote work for multiple devices per household. The service now covers a vast footprint, supported by ongoing network enhancements that prioritize capacity and low latency. This technological edge has allowed T-Mobile to capture switching share from legacy cable providers, whose customers increasingly seek alternatives amid rising prices and service complaints.
The broadband strategy extends beyond fixed wireless. T-Mobile announced new joint ventures to acquire and expand fiber assets through partnerships with infrastructure specialists, targeting efficient growth in markets ready for wired solutions. These moves complement the 5G Home Internet foundation and align with long-term ambitions of reaching approximately 15 million 5G broadband customers by 2030, plus several million fiber subscribers. The dual-track approach positions the carrier to compete effectively against established players such as AT&T and Verizon, both of which have launched their own fixed wireless offerings but trail in scale and speed leadership.
Industry analysts view T-Mobile’s broadband gains as transformative for the U.S. telecommunications landscape. Traditional internet service providers have faced pressure from cord-cutting and demand for flexible, high-value plans. By combining mobile expertise with home connectivity, T-Mobile has created a differentiated ecosystem that encourages customer loyalty and higher lifetime value. In rural and underserved areas, the service fills critical gaps left by slower DSL or satellite options, supporting economic activity and digital inclusion.
Looking forward, the company plans continued investment in network densification and spectrum utilization to maintain its lead. Share repurchases totaling $6 billion in the quarter, along with an expanded authorization, reflect strong cash generation and commitment to shareholder returns. As 5G Home Internet matures, executives anticipate further acceleration through targeted marketing, improved gateways, and potential enterprise extensions.
Overall, T-Mobile’s Q1 2026 performance highlights the growing importance of broadband as a growth engine. With more than 500,000 new connections added in just three months and 5G Home Internet at the forefront, the carrier is reshaping consumer expectations for home connectivity. This trajectory not only bolsters revenue diversification but also cements T-Mobile’s role as an innovator in a market long dominated by a handful of entrenched providers. The results point to sustained leadership in an increasingly competitive and converged wireless-broadband industry.
