No, rmnet is not quite recommended for users User should use MBIM interface ---

Seems yes according to this user > [@EM9191 MBPL install error](https://forum.sierrawireless.com/t/em9191-mbpl-install-error/30205/8): > > no . It did not enumerate /dev/ttyUSB port when I connect EM9191 to one of the USB port. ---

Yes it is MBIM only, you must use package “libmbim-utils” You can start the mbim connection by following these commands: sudo apt-get install libmbim-utils sudo touch /etc/mbim-network.conf sudo vim /etc/mbim-network.conf APN=internet APN\_USER= APN\_PASS= APN\_AUTH= PROXY=yes Your APN will most likely be different “internet” is just the generic APN Then: sudo mbim-network /dev/cdc-wdmX start (X being the integer of your cdc-wdm) sudo dhclient wwanX (X being the integer of your wwan)
