Best-signal federal campgrounds in Illinois
32 federal campgrounds, showing mobile coverage across all carriers. 32 reach at least one carrier on-site, 19 have 5G-fast on at least one carrier, 32 have showers.
On-site signal by carrier: T-Mobile 22 · Verizon 32 · AT&T 32 · UScellular 1 · Dish/Boost 0
Coverage is each carrier's own FCC filing — a comprehensive baseline (every site, every carrier), but carrier-filed and often optimistic. Treat it as a screen, not a promise: real signal can be worse, so confirm before you rely on it. Facility-level, refreshed quarterly.
