T-Mobile
Unlike some other carriers on this list, T-Mobile’s coverage area is too large to cover in one slide. The Uncarrier’s nationwide 5G network covers about 5,000 cities and 200 million people using the 600MHz spectrum (which means it isn’t mmWave).
If you’re curious, you can check T-Mobile’s current coverage map to see if your city or region is included in its nationwide 5G network. At that link, you can also type in your own region or zip code to see if you have coverage.
