Congratulations to the legendary Neville Ray, who was inducted into the Wireless Hall of Fame by the Wireless History Foundation! Neville's contributions to the wireless industry are many, but his impact was really felt when he led the industry into the 5G era at T-Mobile!

Friday night football isn’t just a game - it’s the heartbeat of so many towns across America. And Friday Night 5G Lights is @TMobile’s way of celebrating the teams, schools & fans who make those nights unforgettable.

T-Mobile is at the @IAFC Fire-Rescue International event this week to stand alongside those who protect our communities every day.

We’re here to listen, learn and collaborate with fire and emergency service leaders as we continue to bring @T_Priority — the nation’s first 5G network slice dedicated to first responders — to more communities across the country.

Their insights fuel solutions that save lives.

At #ConnectX2025, @WillAdamsUSA spoke on the panel “Telecom Policy and Priorities in a New Administration.” He covered what’s ahead for the @FCC, @NTIAgov and Congress, from spectrum and permitting to broadband funding programs and beyond. @TMobile values opportunities like this to collaborate and share ideas that help shape the future of connectivity.

Great to hear Chairman Cruz speak so passionately about the need for more spectrum for the wireless industry. If the US is going to be the leader in 5G and 6G we must get a pipeline bill passed. Thank you Sen Cruz for fighting for us.

Loved having lunch with Sue McNeil Sullivan yesterday. Sue decided to retire from the FCC after many years of amazing service to the agency. I had the good fortune to work with Sue "back in the day" when I was at the FCC. Congrats! I can't wait to hear what you do next!
