America’s Largest, Fastest and Most Reliable 5G Network Further Extends its Lead
T-Mobile continues to deliver game-changing Ultra Capacity 5G to people across the country at an unprecedented pace, strengthening its network leadership position with a two-year head start on its competition. T-Mobile continues to lead the industry with the only standalone 5G network able to deliver unparalleled network performance and blazing fast speeds!

T-Mobile ended the year with over 210 million people covered with its Ultra Capacity 5G, reaching over 80% of all T-Mobile customers, and plans to reach 300 million people (more than 90% of Americans) by the end of 2023. When other U.S. operators went all in on millimeter wave limited to parts of stadiums and outdoor areas, T-Mobile executed a multi-band spectrum strategy that includes low-band Extended Range 5G which reaches over 310 million Americans and is expected to cover 99% of Americans by 2023.

With the largest, fastest, and most reliable 5G network, T-Mobile has earned the crown of America’s 5G leader. Nearly every third-party network report in 2021 confirmed T-Mobile is number one in nationwide 5G speed and availability.
