Also Meshtastic.org is a cheap (various <$50 options) open source LoRa based hardware bridge (or standalone device) that can be used with an app over bluetooth (or WiFi web interface).
It supports strong encryption layer and over 1 km/mile per “hop” in most circumstances.
Designed originally for off grid, it’s very flexible and pretty polished.
Abstracts your phone into a UI. Has a whole ecosystem behind it. I’ve been using it for festivals and tracking my vehicles (high theft area) for years.
Very handy should infra not be available. Should be great for protests also :)
