In the 2026 U.S. Wireless Network Quality Study conducted by J.D. Power, customers ranked T-Mobile highest for network quality in five out of six U.S. regions—the first time any carrier has achieved this breadth of regional leadership. This result surpasses T-Mobile’s prior best of two regions and ends a streak of 35 consecutive reports dominated by a single carrier. The survey evaluated voice performance, data speeds and reliability based on responses from more than 100,000 wireless customers, confirming that T-Mobile’s multi-year investments in mid-band spectrum and standalone 5G architecture have translated into perceptible improvements in real-world service.

T-Mobile has broadened its collaboration with Netcracker Technology to migrate its digital BSS/OSS platform to a cloud-native environment, aiming to cut wholesale service launch cycles from an average of six months to under four weeks. The upgraded platform integrates Netcracker’s portfolio of digital billing, service assurance and orchestration tools, embedding end-to-end security controls and automated workflows. By leveraging containerized microservices and API-driven integration, T-Mobile Wholesale expects to onboard new clients 30% faster, streamline operational processes by 40%, and open new revenue opportunities in 5G monetization and enterprise IoT solutions.

T-Mobile’s wholly owned subsidiary announced a registered public offering of $1.15 billion in 5.000% Senior Notes due 2036 and $850 million in 5.850% Senior Notes due 2056. Net proceeds will be used to refinance existing debt obligations maturing through 2028 and for general corporate purposes. The transaction is structured to extend T-Mobile’s debt maturity profile by an average of 12 years while locking in fixed interest rates that are expected to lower annual interest expense by approximately $60 million compared with the refinanced issues.
