Prolink PLE901 4G LTE USB Modem:

This is 19d2:1225 modeswitch'ed to 19d2:1407 (rndis) or 192d:1408 (cdc_ether).

There are no /dev/ttyUSB* devices in either target mode.

Do you folks know how these devices can send/receive SMS without AT commands?

There is a web server on the modem with an SMS form so presumably GET or POST would send SMS commands. How would you receive SMS?

I'm afraid that exceeds the focus of this forum.

On the other hand, it could probably be fun to do research in a hitherto unknown field ...
