Cell service in Yellowstone National Park is limited. Plan maps and messages before you leave areas with reliable coverage.
Checked .
- Coverage areas: Cell towers at Mammoth Hot Springs, West Yellowstone, Old Faithful, Grant Village, Lake Village, and Mount Washburn provide service to most developed areas and the North and West entrances.
- Summer congestion: High visitor use in summer can overwhelm cellular circuits. You may be unable to send calls, texts, or data.
- Offline planning: The NPS App lets you download Yellowstone content for offline use before you arrive.
Should you rely on cell service inside Yellowstone?
Do not rely on cell service for navigation or emergencies away from developed areas. Service exists at some developed sites and near the North and West entrances, but circuits can fail in summer. Text messages usually work better than voice calls. Download offline park maps before you enter areas with weak or no signal.
