Best-signal federal campgrounds in South Carolina
18 federal campgrounds, showing mobile coverage across all carriers. 14 reach at least one carrier on-site, 4 have 5G-fast on at least one carrier, 16 have showers.
On-site signal by carrier: T-Mobile 9 · Verizon 14 · AT&T 11 · UScellular 0 · 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.
