The expansion is a big step towards broader 5G adoption throughout the country — you’ll probably want to be able to connect to a 5G network when you pick up a 5G-ready phone, after all. T-Mobile says it’s working with OnePlus, Qualcomm and Samsung to make sure compatible devices can access the standalone 5G network after a software update.

“Since Sprint became part of T-Mobile, we’ve been rapidly combining networks for a supercharged Un-carrier while expanding our nationwide 5G footprint, and today we take a massive step into the future with standalone 5G architecture,” Neville Ray, T-Mobile’s president of technology, said in a press release. “This is where it gets interesting, opening the door for massive innovation in this country — and while the other guys continue to play catch up, we’ll keep growing the world’s most advanced 5G network.”
