T-Mobile US recently announced that President of Technology Neville Ray plans to retire from the company by Fall 2023 and current Executive Vice President and Chief Network Officer Ulf Ewaldsson will be his successor.

Through his 23 years at T-Mobile, Ray has played a critical role in architecting the Un-carrier’s network strategy – from 2G to 5G – and building and leading a best-in-class team that has brought it to life.

“Under Neville’s network leadership we have accomplished so much together, and it’s amazing to think that milestones he’s helped T-Mobile achieve – the many network firsts, breakthroughs and innovations – have brought us to where we are today, taking the crown as the nation’s overall network leader,” said T-Mobile CEO Mike Sievert.

“There are so many things Neville has contributed to this company but one of the most important has been his commitment to building the best, most effective Technology team in this industry that will continue to deliver for our future. Neville and his team have worked tirelessly to bring the Un-carrier from last to best in network performance and made T-Mobile’s network a true competitive weapon. What’s even more exciting is that we’re just getting started! As this next chapter of the Un-carrier story is beginning to unfold, we owe a lot of gratitude to Neville for all he’s done to carve this path that will continue to lead us into the future,” Sievert added.

Ewaldsson joined T-Mobile in January 2019 as senior vice president of Technology Transformation and was promoted to EVP and Chief Network Officer in 2021. Ewaldsson currently leads a nationwide field team responsible for the build, operation, and maintenance of T-Mobile’s network. In just four years since joining the Un-carrier from Ericsson, Ulf has led a team that has played a critical role in achieving milestones for T-Mobile as it has become a 5G leader and now is emerging as an overall network leader in the U.S. He established and drove a record-setting pace to build out the Un-carrier’s nationwide 5G network and rapidly expand T-Mobile’s coverage footprint.

"Ulf and team have led the historic merger integration, unlocking billions of dollars in synergies ahead of schedule, while simultaneously improving network satisfaction among customers, and reducing churn to record lows - an amazing set of accomplishments," continued Sievert. "Ulf brings the right combination of customer centricity, leadership, and deep technology experience to write the next technology chapter at T-Mobile."

Current senior leadership team members Executive Vice President and Chief Information Officer Brian King, Executive Vice President and Chief Technology Officer Abdul Saad, and Executive Vice President Advanced and Emerging Technologies John Saw will remain in their roles, reporting to Ewaldsson after the transition.
