FCC documents indicate that the LG V20 variants for Verizon, AT&T, and T-Mobile will be the first phones to support LTE in the new band 66.
Band 66 includes the AWS-1, AWS-3, and AWS-4 frequencies. Verizon, AT&T, and T-Mobile all purchased new AWS-3 spectrum in 2015, but have yet to deploy it. When they do, it will require phones that support band 66. AWS-1 — also known as band 4 — is already deployed by all three companies.
AWS-4 is owned by Dish Networks, which has yet to announce firm plans for that spectrum.
