Here's how to send off-grid, encrypted text messages from an old, junk cell phone, without cell service, WiFi, or satellite. All you need is a LoRa radio and the Meshtastic app. You connect to the LoRa radio with Bluetooth, then the radio transmits your messages wirelessly over the local mesh. No licenses, no subscriptions, encrypted and anonymous. #tiktokgrowthchallenge #meshtastic #meshcore #offgrid #comms
