I inserted a sim card in the sim card slot of my laptop and was expecting the mobile broadband option to appear on the system menu, but it doesn't. I have a Fibocom L860 and WWAN is also enabled via bios so I'm thinking that it should work. As far as I know, Fibocom L860 should be supported in Ubuntu.

I checked by running mmcli -L on the terminal and it says that there were no modems found. I also tried to run sudo modem-manager.mmcli -L, but I keep getting error: couldn't get bus: Could not connect: Permission denied. I tried installing a modem manager gui, but it's still not able to recognize my sim card.

I tried solving my problem using this solution but there's no CD/DVD drive option appearing, so I couldn't proceed with it.

I am not sure why this problem is happening. Is there a way to check if the problem is with the sim card, the sim card slot, or anything else?

Edit: I switched the OS to Windows to check if it was a hardware problem, but my sim card was easily recognized and I was able to use it to access the internet.

Switching back to Ubuntu, I entered nm-connection-editor on the terminal and added a mobile broadband connection for my sim card. I also tried running mobile broadband by entering sudo service mobile-broadband-connection start, but I still cannot access the Internet, and mobile broadband option still isn't appearing in the system menu either.

What could be causing this problem?

  • Do you have the driver ? Apparently, it is quiet hard to use Fibocom L850 with Linux and X1 Carbon : is it also difficult with Fibocom L860 ? Search about Fibocom L850 and you may have some answers. I didn't find any Linux driver. – user985091 Aug 14 '19 at 09:16
  • i checked via terminal and wwan driver is enabled. according to this, L860 should work: https://www.reddit.com/r/LinuxOnThinkpad/comments/c3lxky/fibocom_l860gl_under_linux/ it's difficult to find answers regarding 850, and 860 seems to redirect me to 850 so it feels like a dead end – xjm Aug 14 '19 at 09:31

  • @NikosAlexandris thanks! i suspected as much. i don't think they'll be supporting L850 at all, but maybe hopefully for L860 they'll have support – xjm Sep 13 '19 at 00:30

i tried generating an automated test and mobile broadband is missing some modules. seems like it's not yet fully supported.

I had the same problem as yours and managed to get it working using the following command:

sudo usb_modeswitch -v 0x03f0 -p 0x9d1d -u3 (change the 03f0 and 9d1d to the ID displayed for the device when you run lsusb)

If this is successful, then mobile broadband will show up in the system menu.
