T-Mobile is beginning to launch 5G network upgrades that utilize assets of the former Sprint network. In Philadelphia, customers can now access 5G using both low-band (band 71) and mid-band (band 41) radio spectrum, offering better mix of coverage, capacity, and speed. T-Mobile will make this upgrade next in New York City, where the company also operates a mmWave 5G network, so customers there will be able to access 5G in all three classes of radio frequencies, offering an even better experience. T-Mobile is also launching low-band 5G in Detroit, St. Louis, and Columbus, Ohio today. Finally, the Sprint-branded Samsung Galaxy S20 will gain access to T-Mobile's "nationwide" low-band 5G network later this month.
