When hiking in remote desert or mountain areas, cell service can disappear quickly. Modern smartphones like the Apple iPhone and Google Pixel now include satellite-based emergency messaging — a feature that lets you contact emergency services even when no cellular or Wi-Fi signal is available. This guide explains how it works, when to use it, and how to activate it on your device.
When to Use Satellite Emergency Messaging: Use this feature only when you have no cellular service and you’re facing a serious or life-threatening emergency such as:
Injury or medical emergency
Becoming lost or stranded
Encountering dangerous wildlife or flash flooding
Unable to return to your vehicle safely
Satellite messages are slow and power-hungry, so they should be reserved for genuine emergencies.
Apple iPhone Emergency SOS via Satellite: Available on iPhone 14 and newer models, this feature connects directly to satellites when no cell network is detected. The phone guides you to point toward the nearest satellite and sends a short text to emergency services or Apple relay centers.
Key steps: Attempt to call emergency services — if no network is found, you’ll see “Emergency Text via Satellite.” Follow the onscreen directions to connect to a satellite. Answer the guided questions about your emergency. Messages are relayed to local emergency responders.
You can also share your location with “Find My” via satellite even when off the grid.
Google Pixel Satellite SOS: Available on the Pixel 9 series and select newer models, Google’s Satellite SOS works similarly to Apple’s. It uses GPS and direct satellite connection to send emergency details and your location to dispatchers. You can also choose emergency contacts who will receive updates.
Steps: When no service is available, open “Safety” or press the power button five times quickly. Choose “Emergency SOS” and follow the prompts to aim at the satellite. Type or select preset emergency messages. Your phone will transmit your location and details to responders.
The Pixel can also share your situation with chosen contacts automatically.
Hiker Tips: Always carry your phone fully charged; bring a power bank. Download offline maps before leaving coverage areas. Stay in open areas when using satellite messaging — trees, canyons, or cliffs may block the signal.
Practice opening the Emergency SOS feature before your trip so you know how it works. Satellite messaging can be a lifesaver when traditional communication fails.
