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?
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 the03f0and9d1dto the ID displayed for the device when you runlsusb)If this is successful, then mobile broadband will show up in the system menu.
