JBM is a connection manager for wireless broadband services with the goal of supporting all functionality present in the official Telsra Connection Manager. Currently JBM supports creating a basic connection, send/receiving SMS messages, and using the Service Menu (for recharges etc). JBM automatically detects the appropriate tty for both connections and controls (SMS etc), while providing feedback to the user on connection status (Signal Strength and Network Type).
Officially only the ZTE MF626 is supported but any ZTE modem should work (and possibly others).
