T-Mobile has added another feather to its 5G cap with coverage in all 50 states, thanks to a roaming deal in Alaska.

T-Mobile has struck a deal with GCI to allow T-Mobile customers to roam on the company’s 5G network while in the Anchorage, Alaska area. In turn, GCI customers are able to roam on T-Mobile’s nationwide 5G network.

“The massive nationwide 5G network we’re building and expanding by the day – paired with important partnerships like this – extend our 5G leadership over the competition and deliver meaningful 5G experiences to our customers,” said Neville Ray, president of technology at T-Mobile. “Now, our customers with 5G devices can keep 5G service when in Alaska. And to GCI customers, welcome to nationwide 5G!”

“GCI and T-Mobile have a long history of ‘firsts’ together,” said GCI President and Chief Operating Officer Greg Chapados. “GCI and T-Mobile launched the nation’s first LTE roaming partnership in 2014 and were the first providers to partner together to deliver voice over LTE service. Today’s partnership marks another first and a tremendous milestone! GCI congratulates the T-Mobile team on being the first wireless provider to offer 5G service in all 50 states. The partnership is a win for both companies and for GCI customers who will be able to access 5G service on the nation’s largest 5G network.”

The move is a nice bragging point for the magenta carrier, making it the only one to offer 5G service in all 50 states. The deal is an even better one for GCI, as its customers gain access to T-Mobile’s 5G network throughout the country.
