US Cellular's 5G network will go live in select areas of California, Maine, Maryland, New Hampshire, North Carolina, Oklahoma, Oregon, Texas, Virginia, Washington, and West Virginia in the second half of this year. US Cellular hasn't yet said exactly where in these states its 5G will be available.
There are currently two states with access to US Cellular's 5G network, Iowa and Wisconsin, where the service went live earlier this year. So this newly announced expansion is going to greatly expand US Cellular's 5G coverage.
US Cellular is using 600MHz low-band spectrum for its 5G network. It currently sells a handful of 5G-capable smartphones, including the Samsung Galaxy S20 series, the Galaxy A71 5G, and the LG V60 ThinQ 5G.
