If you're a T-Mobile customer, you've probably already seen improvements since the company essentially completed its nationwide rollout of 5G in late 2021. Its 2.5GHz service offers a nationwide average of about 150Mbps, according to Opensignal, with speeds that can easily reach 400Mbps or more in densely covered areas. Both of those measurements should continue to climb as the carrier continues to "densify" its network with new hardware and infrastructure.
For Verizon Wireless subscribers, the wait is either over, or will be soon. The company's C-Band launches operate between 3.7GHz and 3.98GHz, putting them in the same sweet spot as T-Mobile's.
Early tests from our sister site CNET have shown speeds as high as 1.4Gbps under ideal conditions, with 400Mbps being available over a wider area, and 90Mbps being possible even when deep within an underground garage.
Verizon's claims its initial rollout (which was forced to skip US airports over interference concerns) includes a total of 46 "major metro areas." Each rollout also measures in square miles, unlike previous high-band launches that would be lucky to reach a full city block. The company expects to continue expanding its markets in the coming year.
AT&T subscribers might have the longest to wait of all the "Big Three" carriers. Its initial rollout saw C-Band go live in a much smaller number of cities, eight specifically. However, like Verizon it has big ambitions for the future, claiming its new spectrum of 5G services will reach 200 million people by the end of 2023. Unfortunately, it hasn't provided any details on where these potential customers might be located. However, thanks to a recent agreement being reached between AT&T, Verizon, and the Federal Aviation Administration, US airports may soon get access to the new technology as it continues being carefully rolled out around air travel hubs in a manner that won't impact US commercial flights.
