For the first time in its history, T-Mobile has been rated highest for network quality in five out of six U.S. regions in the J.D. Power 2026 U.S. Wireless Network Quality Study, surpassing its previous best performance of two regions. This achievement ends a 35-report streak in which only one carrier led the category and underscores the impact of T-Mobile’s sustained investments in 5G spectrum, tower infrastructure and network engineering. Independent real-world measures support this shift: Opensignal’s analysis of billions of user-generated data points awarded T-Mobile wins in 12 of 16 performance categories last week, while Ookla® Speedtest®, based on more than half a billion real-world tests, named T-Mobile America’s Best Network in the second half of 2025. President and CTO John Saw highlighted that this customer-driven recognition confirms the company’s strategy of pairing a superior network build with unmatched value and benefits, delivering faster speeds, lower latency and stronger voice performance across the country.

T-Mobile has deepened its collaboration with Netcracker Technology to migrate its digital wholesale platform to a cloud-native architecture, aimed at shortening service launch cycles from months to weeks while embedding advanced security and privacy protections. The expanded deal leverages Netcracker’s BSS/OSS portfolio to streamline partner onboarding, simplify operations and enable digital-first business models, opening new revenue streams with lower operational friction. In parallel, T-Mobile’s wholly owned subsidiary has filed to sell $1.15 billion of 5.000% Senior Notes due 2036 and $850 million of 5.850% Senior Notes due 2056, with net proceeds earmarked for debt refinancing and general corporate purposes. The company will report fourth-quarter and full-year 2025 financial results on February 11, 2026, positioning itself to discuss the impact of these initiatives on its capital structure and growth trajectory.
