I installed the EM06-E modem and the Modem Manager Gui. I can see the modem but I am getting the following error: “Modem is not ready for operation. Please wait while modem is being prepared…” I have also install a T-Mobile sim and added a connection for it. Any thoughts on fixing this are appreciated.
I’m a little rusty on this but if I had to debug this I would try talking to the various virtual serial ports of the modem using tio (/dev/ttyUSB…) and sending “AT” followed by enter to get an “OK” response, then try various status/diagnostic commands from the modem’s manual.
