Outdoor coverage each carrier reports to the FCC at this campground's map point, and the nearest mapped coverage within about half a mile. The FCC map only includes 4G LTE at 5/1 Mbps or better and 5G; a weaker signal, a text, or an emergency call may still get through, but don't count on it. These are carrier predictions, not measurements, and can be wrong either way: real service in canyons, under trees, and inside a tent or vehicle is often weaker. 5G speeds are the FCC's 7/1 and 35/3 Mbps tiers. This product uses the FCC Data API but is not endorsed or certified by the FCC.
