Grand Teton National Park Cellular Coverage
Grand Teton National Park has an excellent cellular site on the top of Signal Mountain with both GSM and CDMA coverage. However, that site is often overwhelmed by a large number of seasonal users. As a result, 9 new cell sites are being constructed along the Teton Park Rd and rt. 189 corridor with completion estimated in 2021.  
See the Map of Proposed Cell Sites.  Also, See Our Notes.

Notes About Wireless Coverage in Grand Teton National Park:
  • In addition to the cellular site on Signal Mountain there are several sites located around the town of Jackson that reach into the south half of Grand Teton National Park, including at Jackson Hole airport. If the proposed cell sites are constructed, extensive coverage and capacity will be available in and along the entire east-facing Teton range.  

  • Variations in topography and elevation affect cellular coverage within the Teton Range significantly.

  • The coverage area shown is approximate. Teton Park coverage has been field checked but has not been updated recently.

  • The west side of Grand Teton National Park has some cellular service available, mostly provided from sites in the valley in Idaho to the west.  This coverage is somewhat spotty but improves with altitude.
