FIRST AID · NO SIGNAL
Offline first aid by SMS
Someone's hurt, the how-to videos won't load, and the nearest ranger station is a day away. A text message still gets out — and a text is all you need to ask.
First, the rule that matters: in a life-threatening emergency, call 911 or hold your satellite device's SOS button. NoService AI is an information service, not a rescue or medical service. It's for what to do while help is coming — and for the hundred smaller injuries that don't warrant a helicopter.
How it works with no internet
Text your question to +1 (209) 379-8911 from any phone or satellite messenger. An AI reads it and replies with the most critical steps, compressed into a single SMS — because at one bar of signal, a 160-character answer arrives and a web page doesn't.
Follow-ups continue the thread: “bleeding stopped, how do I dress it?” gets the next step.
What to ask about
- Bleeding & wounds — pressure, dressing, when a wound needs professional closure.
- Sprains & suspected fractures — tape vs. splint, when weight-bearing is safe.
- Cold & heat — hypothermia stages, frostbite, heat exhaustion vs. heat stroke.
- Bites & stings — snakes, spiders, ticks, bees; what helps and what's a myth.
- Burns, blisters, dehydration, altitude — the unglamorous majority of trail problems.
Ask specifically — “rattlesnake bite on calf, 3 hrs from car, what now?” — and you'll get specifics back.

Guidance is not a kit. Carry a real first-aid kit and, better, take a wilderness first aid course. Texted answers help you use what you have — they don't replace training or judgment.
FAQ
How can I get first-aid information without internet?
Text the question. It works over one bar of cellular signal or any satellite messenger that can reach a US number — details for satellite devices.
Is this a replacement for 911 or SOS?
No — emergencies go to 911/SOS first, every time. We handle the “what do I do right now” and the injuries that don't need rescue.
What can I ask?
Any practical first-aid question. The reply is one SMS with the most critical steps, so act on it and follow up for the next step.
Should I still carry a kit and get training?
Absolutely. This is a backstop for your memory under stress, not a substitute for preparation.
