OK but kind of outdated and incomplete. Meshcore is largely competing with Meshtastic nowadays: https://meshcore.co.uk/

To remember: LoRa only permits small text messages. Don't even think about images, voice nor binary files (I mean it).

Another option is APRS using satellite connections through a cheap chinese walkie-talkie (Quangsheng UV-K5) for 20 euros to send text messages.

You could just about squeeze voice down LoRa with a really low-bandwidth codec, as really aggressive codecs can manage < 0.5 kbps. If you want to sacrifice voice quality but use standard codecs, the military MELPe codec has 600 bits/s as one of its standard modes.

And yet such implementation never was seen outdoors.

Because it would likely violate the restrictions setup for the LoRa frequency. Using a normal walkie-talkie has none of those limitations while being cheaper and more versatile.
