We all know Signal, Matrix, Telegram, SimpleX, etc... But if you can't access the internet you can't communicate. Pretty logic. But would it be possible, at least theoretically, to create an app that permits to message people even if the internet goes down?

It might be a dumb question I really have no idea to be honest.

yggmail specifically, probably not. yggdrasil uses TCP/IP and the Meshtastic latencies to perform connections would be too high AFAIK. It would probably only work in a fairly well-connected network. yggdrasil could be used directly over a WiFi protocol but it would need fairly good reception to function.

N.B. I haven'texperimented with this myself.
