Best cell phone coverage in Wisconsin Wisconsin, statewide · AT&T · T-Mobile · Verizon

The carriers' outdoor figures run from 59.9% (T-Mobile) to 74.7% (Verizon) of Wisconsin, but 17.3% of Wisconsin's area is water and carriers differ in whether they file coverage over water. The gap is no bigger than the water, so the FCC figures don't show any carrier covering more of the land.

Figures are the share of Wisconsin's area where each carrier reports 4G LTE or 5G service to the FCC, as of December 31, 2025. The area includes water (17.3% of it), which some carriers file coverage over and others don't. A state or city figure can hide dead spots, so check your own ZIP code below.

Outdoor is the share of the area where the carrier reports 4G LTE or 5G to a phone standing still outdoors; in car is the share it reports to a phone in a moving vehicle, which is always lower. Indoor signal is not part of the FCC filing and can be weaker than either.

Share of Wisconsin's area where at least one carrier reports each technology outdoors. "5G 7/1" means 5G of at least 7 Mbps down and 1 Mbps up, "5G 35/3" at least 35/3 Mbps, the two speed tiers the FCC publishes. The FCC summary does not split 5G by carrier.

Choosing a carrier in Wisconsin

On land, the FCC figures don't separate the three carriers in Wisconsin, so price, data allowance and contract terms can decide it. Check your own street in each carrier's map, because a city-wide share can hide a dead spot.
