T-Mobile is also expanding its 5G network to Detroit, St. Louis and Columbus, Ohio. It will continue to use its low-band 600 MHz spectrum as the foundation of its 5G network in these cities.
There are a few perks for Sprint customers, too. They can now roam on T-Mobile’s LTE network (as long as they have compatible devices) in areas not covered by Sprint LTE. And if they have a Samsung Galaxy S20 5G, they’ll have access to T-Mobile’s nationwide 5G beginning later this month. According to T-Mobile, that covers more than 5,000 cities and towns — or more than one million square miles across the country.
