What is this?
This monstrosity bridges a USB 3G modem to internet relay chat (IRC), allowing one user to send and receive SMS messages via the bridge. Using it requires running your own IRC daemon (or having a friendly IRC daemon somewhere that lets you make large numbers of connections from one IP address).
This is also the spiritual successor of matrix-appservice-sms, in that it does the same thing as matrix-appservice-sms, except way more reliably and for a different protocol.
How do I set it up?
Documentation is currently being worked on, and will be available soon! For now, though, this project is still in a pre-alpha phase.
