Building a Meshtastic transceiver for sending text messages without cell service and/or internet access is a good way to provide communication for your group in camp or survival situation to check in or communicate with your team. The range between two people is somewhat limited, but in an open area, it can go quite far (records are greater than 150 miles). I have tested them for over 1 mile where one device is in a home surrounded by antennas, metal, etc., and the other device outdoors with buildings and walls that limit the distance you can communicate. In the open, I easily got 10 miles.
