Please add support for ZTE MF79 LTE modem if it is possible. Modem when inserted is listed in USB devices but neither LTE interface appears nor PPP (serial) interface configuration is possible. Attached two supouts (in zip archive) - one with modem attached to USB in RNDIS mode and other when in MODEM mode.

Have you continued trying to use this USB Modem with RouterOS?
Was it successful? v6 or v7?
