First, check https://meshmap.net/ to see if anyone is around. If not, you can be the first (it just will be very quiet).
Next look for a device. I’m partial to this one: https://www.seeedstudio.com/SenseCAP-Card-Tracker-T1000-E-for-Meshtastic-p-5913.html - just make sure whatever you get it’s spec’ed for your region.
Then just download the Meshtastic app on your Android or iOS device and you’re set.
I’d rather be 50 get money old in 2024 than be 2024 get money old in 50?
… What?
