See cell coverage on the map
If you work from the road, stream in the evenings, or just want to reach family, cell signal is part of picking a campsite. VistaBound shows carrier coverage two ways: as map layers you can toggle on, and as a per-carrier signal readout on each campground card.
Coverage layers on the map
Open the Layers menu in the top-right corner of the Explore map (or the trip map in the planner) and toggle on any of:
- T-Mobile coverage
- AT&T coverage
- Verizon coverage
Each carrier paints a translucent shaded area over the regions it reports coverage. Turn on more than one to compare — the fills are semi-transparent so you can see where they overlap and where only one carrier reaches. Turn a carrier off to clear its shading.
Coverage on the campground card
Open any campground and look for the Cell coverage box. Each carrier gets a small signal meter (0–4 bars) estimating the strength at that campground:
- Strong / Good — 5G, likely fine for video calls and streaming
- Fair / Weak — 4G LTE; usable, but don't count on heavy uploads
- No signal — no reported coverage there
- No data — we don't have a coverage estimate for that spot
Where the data comes from
Coverage comes from the FCC's National Broadband Map (the Broadband Data Collection), which carriers file with the federal government. It's a propagation model — an estimate of where signal should reach — not a real-world speed test. Terrain, trees, your device, and network congestion all matter, so treat it as a strong hint, not a promise. The FCC refreshes this data about twice a year.
Cell coverage is a trip-planning tool, so you'll find it on the web maps and campground cards — not as a layer in the turn-by-turn driving apps, where the map stays focused on what you need behind the wheel.
