US Cellular has the fifth largest network in the United States. Unlike Verizon, AT&T, T-Mobile, and the nascent network from Dish, US Cellular is a regional (non-nationwide) network. A full-screen map showing coverage throughout the whole US is available here.

Most US Cellular subscribers still have nationwide coverage thanks to a roaming agreement with AT&T. Below, you can toggle between the maps of US Cellular's native coverage and the map of AT&T's coverage.

US Celluar 5G Coverage

US Cellular offers both 4G and 5G coverage. Further, US Cellular subscribers roaming on AT&T's network have access to AT&T's 4G and 5G services. By default, the map shows both 4G and 5G coverage. However, you can switch to the 5G-only map.

Crowdsourced Coverage Map

Coverage Critic offers a map of crowdsourced coverage information from AT&T. You can switch to the crowdsourced map from the settings menu. No crowdsourced coverage data is available for US Cellular's native network.
