1. Call 999 (or 112), ask for Police, then Mountain Rescue. Give the grid reference first. 2. No voice signal? Text 999 — this only works if the phone was registered beforehand: text the word register to 999 and follow the reply. Do it today. 3. Stay put unless unsafe, keep warm and dry, keep the phone on and charged, and make yourself visible. 4. Six blasts of a whistle or six torch flashes, a minute apart, is the mountain distress signal. Works offline. Fill in your details now, not on the hill.

1. Call 911 and ask for Search and Rescue — in most states the county sheriff runs it. Give your latitude and longitude first. 2. No voice signal? Text 911 works in many counties but not all; if it fails you will get a bounce-back message. Satellite SOS (iPhone 14+, Garmin inReach, PLB) works where there is no signal at all. 3. Stay put unless unsafe, keep warm and dry, keep the phone on and charged, and make yourself visible. 4. Three of anything — whistle blasts, torch flashes, shouts — is the distress signal. Works offline. Fill in your details now, not on the trail.
