T-Mobile Launches Voice Over 5G

T-Mobile has announced the commercial launch of Voice Over 5G (VoNR, or Voice Over New Radio). The feature is now live for customers in limited areas of Portland, Ore. and Salt Lake City, making T-Mobile the first carrier in the country to achieve the milestone.

With VoNR, the Un-carrier can keep devices always connected to 5G and enable future transformative applications that require a seamless 5G connection. The Un-carrier plans to continue its VoNR rollout to many additional areas this year.

"We don't just have the leading 5G network in the country. T-Mobile is setting the pace for providers around the globe as we push the industry forward - now starting to roll out another critical service over 5G," said Neville Ray, President of Technology at T-Mobile. "5G is already driving new levels of engagement, transforming how our customers use their smartphones and bringing unprecedented connectivity to areas that desperately need it. And it's just going to get better thanks to the incredible T-Mobile team and our partners who are tirelessly innovating and advancing the capabilities of 5G every day."


Standalone 5G removes the need for an underlying 4G LTE network and 4G core. In the near term, customers will notice slightly faster call set-up times, meaning less delay between the time they dial a number and when the phone starts ringing. Longer term, a standalone 5G network will allow T-Mobile to use advanced capabilities like network slicing that rely on a continuous connection to a 5G core.

Currently, you'll need a Samsung Galaxy S21 5G to try out VoNR but support will be added for more 5G smartphones this year including the Galaxy S22.
