What to Do If Someone Is Hurt Hiking (and You Have No Signal)

Bykylegosnell

When someone gets hurt on the trail and your phone says “No Service,” the first ten minutes matter most. Help may be hours away, so what you do first — and in what order — can make the difference. Here’s a calm, practical sequence you can follow, based on the patient assessment taught in wilderness first aid courses.

This is education, not medical advice. If you have any way to reach help, call 911 or your rescue contact first.

1. Stop and make sure the scene is safe

Before you rush in, take a breath and look around. Rockfall, moving water, lightning, unstable footing, an avalanche slope, or whatever hurt your partner can hurt you too. Wilderness first aid courses teach that your safety comes first, because an injured rescuer helps no one. Then ask what happened, check whether anyone else is hurt, and protect yourself from blood and body fluids with gloves if you have them.

2. Get help coming — even with no signal

“No Service” doesn’t always mean no options:

  • Try 911 anyway. Emergency calls can sometimes connect on another carrier’s network when your own shows no bars.
  • Use satellite SOS if your phone has it. iPhone 14 and newer and the Google Pixel 9 series can send emergency messages by satellite with a clear view of the sky (which phones have satellite SOS). A dedicated messenger such as a Garmin inReach, Zoleo, or SPOT works too.
  • Text if you can’t call. A text sometimes gets through when a call won’t. Dispatchers say it simply: call if you can, text if you can’t.
  • Send people for help. If no device works, send two people together toward signal or the trailhead — never one alone. Give them your exact location (GPS coordinates if you have them, or the trail and landmarks), what happened, how many are hurt, and what you need. Note the time they leave.

If you’re alone with the patient, stay with them unless there’s truly no other way to get help, and make yourself easy to find: three whistle blasts, bright gear spread in the open, a light at night.

3. Check the things that can’t wait

Trained responders work through a quick primary check, often remembered as ABCDE. Even without training, you can notice the same priorities:

  • Are they awake? Talk to them from the front so they don’t turn their head: “I’m here to help — can you hear me?”
  • Are they breathing normally? Watch the chest and listen for up to 10 seconds. If they aren’t, tell the dispatcher right away — they will coach you.
  • Is there heavy bleeding? Firm, direct pressure on the wound with a cloth or gloved hand is the first step. Keep pressing.
  • Could they have hurt their neck or back? After a fall, crash, or hard hit, don’t move them unless they’re in danger where they are.

4. Protect them from the cold

In the mountains, cold is a threat even in summer. Get something between them and the ground — a pad, pack, or clothing — add dry layers (give them your jacket), block the wind, and cover the head and neck. Professional care can be hours or even days away in the backcountry, so plan to care for them for a while (REI: wilderness first aid basics).

5. Reassure them, and stay

Fear makes everything harder. Keep your voice calm and keep talking: “Help is on the way. I’m staying right here with you.” Tell them what you’re doing before you do it, and don’t leave them alone. Unless a dispatcher tells you otherwise, hold off on food and drink.

6. Write down what rescuers need

When help arrives, facts beat guesses. Note what happened and when, what they say hurts, how awake they are, their breathing and pulse if you can count them, anything that changes, and your exact location. Write the time next to each note.

Practice it before you need it

The Wilderness Medicine AI Field Assistant walks you through these steps one calm question at a time — out loud if you want, and with no signal once you’ve set it up. It records your answers and builds a handoff report with your GPS location, a short message sized for satellite texting, and a QR code rescuers can scan. Not certified? Bystander mode keeps it simple: stay safe, keep them safe, and record what rescuers need.

Before your next trip: open wildernessmedicine.ai while you have signal, tap Enable Offline Version, and add it to your home screen. Then take a wilderness first aid course — nothing replaces hands-on training.
