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.
FIRST AID · ALWAYS FREE
First aid is always free. Even if you never pay us. Urgent first-aid questions (CPR, choking, severe bleeding, burns, stings, poisoning) get a full answer free, for everyone, at any balance. So set it up as insurance you hope never to use: send one free text now and the number is in your phone for the worst day, whether or not you ever buy anything.
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 text or two - because at one bar of signal, a short text 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.
Do first aid questions cost a message?
No. Urgent first-aid questions (CPR, choking, severe bleeding, burns, stings, poisoning) are answered in full for free, for everyone, even at zero balance, up to a daily safety cap. They never count against your pack or subscription. In a life-threatening emergency, use 911 or your device's SOS first.
What can I ask?
Any practical first-aid question. The reply is short and carries 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.
What if the answer does not come and I need it now?
Do not wait on us. Act on your training and what you have, and use 911 or your device's SOS if the situation is serious. If the text failed, move to open sky or a spot with a bar of signal and send it again: a credit is spent only when an answer reaches you.
How is this different from a first-aid app or a saved PDF?
An app gives you an index to search while your hands are busy. Here you describe what is actually in front of you, in your own words, and get the steps that fit it, then ask the next question. Both are worth having: the app never needs signal, this one needs a single bar.
