During the first T-Mobile 5G test in New York City, the service scored 493 Mbps using a Verizon phone.
T-Mobile’s feat becomes greater when you understand that the carrier is using much less spectrum than Verizon is. Allnet Insights says T-Mobile is using 80MHz of spectrum in New York, which would make its theoretical maximum speed 500Mbps, but I’ve also heard that T-Mobile is using 100MHz, which would make the theoretical maximum 625Mbps.
