I have a quectel em120r-gl 4g lte cat12 card already put in the computer. It came with windows 10 preinstalled and this card is working perfectly, I could see a mobile broadband connection option in setting and network options also. I just installed ubuntu and I am not able to find that here. I tried to check additional drivers but got nothing. I also tried mmcli -L and I am getting No modem found as response. Is anyone using the preinstalled modem in ubuntu thinkpad x1c gen 9 successfully? I am not even sure if I should continue looking for solutions or is it not possible?

Here is some more response:

A little more information will be required to answer this question. Could you [edit] the post to include the Terminal output of `lsusb` and `lspci`. This will show some specific details about the hardware in your system

[Looks like you'll need Kernel 5.13 or newer](https://forums.lenovo.com/t5/Fedora/Lenovo-X1-Gen-9-Fedora-and-Quectel-EM120R/m-p/5081326) to use the device with Ubuntu. Fortunately, Lenovo worked with Quectel to make it work. *Unfortunately*, this means you will need to either upgrade the kernel on your own or upgrade to the 21.10 interim release to use the modem ...

I had a problem with the same hardware and got it working with the same fcc unlock code. Some guidance: https://askubuntu.com/questions/1414662/quectel-em120r-gl-modem-seems-to-work-but-sim-missing-or-not-detected/1414674#1414674

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
