As this graphic demonstrates, enhanced cell phone service is not always reliable in the Big Bend.

Big Bend is a very remote park far removed from many of the trappings of the communication networks you may be used to.

Satellite Phone
This specialty phone is the most reliable communication tool you can bring to the park. They work almost everywhere in the park except for narrow canyons such as along the Rio Grande. In emergencies, you may have to climb to get to where your sat phone can communicate with a satellite.

Don't Depend on your Cell Phone
Limited cell phone coverage is available in the Big Bend area. Reception depends on both the service you use and your location within the park; lower elevations and mountains often block signals. Do not depend on your phone to work in the Chisos Basin or remote portions of the park. Have a backup communications plan.

Currently a cell tower is located in Study Butte. Service can be found intermittently to Panther Junction, as well as near some high ridges.

Be a Courteous User
Many of your fellow visitors to Big Bend have come here to escape the trapping of modern life, such as cell phones. As a courtesy to other visitors, please be considerate when using your cell phone by talking on the phone outside, and in a quiet voice.
