When I insert a SIM-card on my Lenovo Thinkpad x1 carbon, it doesn’t recognized the SIM-card. The SIM-card does work on my phone.
Do I need to enable/install something or does the OS not support SIM-card?
It’s the broadband modem device itself that needs to be considered here. To start with let’s see how it is reported…
lsusb
usb-devices
It’s likely that using a more recent kernel will be required in order for the kernel to support it, and there may still be other issues to getting it handled properly. If you want to try this, follow the instructions I provided in this post. When you reboot, you’ll be able to choose the desired kernel from the advanced options in the grub menu.
FWIW, an Ubuntu thread discussing similar…

Hi, sorry for the late answer but i already had that rep, don’t think that kernel is the problem. Not sure but, I am not using any usb devices for the SIM-card is more like a port. Anyway, this is what i get from lsusb and usb-devices:

I have tried rfkill unblock all just to see if it was blocked. Nothing changed.
Well I could be wrong since I am here asking for help hehe.
Ok, but often these internal mobile broadband devices are attached to the USB subsystem. However I agree that doesn’t appear to be the case here.
This might be it…

No driver loaded though…
Others have reported similar issues with getting this hardware working…

Looks like work in progress.
Scratch that - it’s a Validity Sensors, Inc fingerprint reader.
Strange that it doesn’t show up in your lsusb output. Disabled in the UEFI BIOS perhaps?
Just went and checked my BIOS, nothing strange there. All kind of ports about network/wireless was enabled. Only thing that may or may not affect the problem is BIOS version. It’s from 2015 Jan. (The month they released the laptop). I am not 100% sure, but it seems like the factory version should support the port.
Found this on the Arch wiki https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Carbon#WWAN_.28Mobile_broadband.29
Hi,
It didn’t work. Had to create the file :
/etc/modprobe.d/avoid-mbib.conf
But still nothing changed after a reboot. 
Checked lsusb and usb-devices both was the same
Just an idea: can you take the SIM out, start
dmesg -w
, then reinsert the SIM and have a look if dmesg displays info on it?
But Thanks for trying 
Doesn’t register anything. It’s like the port doesn’t exist …
Anything in BIOS / UEFI settings ? Is modemmanager installed ?
As there is no chipset listed it’s as if the device is disabled, so no driver loaded either. Therefore, ModemManger has nothing to work with. I had found the archwiki page as well (which mentioned the Ericsson device), but this Ubuntu page mentions the possibility of a Sierra Wireless device (connected to the USB subsystem)…
https://forums.lenovo.com/t5/Linux-Discussion/Mobile-Broadband-X1-Ubuntu-16-04/td-p/3720487
But the person that are asking for help on that page have his port activated or detected by the OS, and
mmcli -m X
doesn’t work for me since its ubuntu. And I tried too somehow trigger the card with ModemManager… Dead end. And run a debug doesn’t seem like it’s necessary since the system doesn’t even find it. So the debug will not even show something useful.
Think this is the problem. Tried the ModemManager --debug… Found this
[main.c:218] name_lost_cb() Could not acquire the "org.freedesktop.ModemManager1" service name
[mm-base-manager.c:842] main() ModemManager is shutdown
And before this you can see all kind of mm-plugin-manager loaded successfully. Guess this is my problem?
Tried (in SU)
find / -type d -name "..freedesktop.."
got Permission denied in :
/run/user/1000/gvfs
Only folder searched…
You can check the ModemManager service status with
systemctl status ModemManager
However, as the hardware is not detected/active, that needs to be sorted first. (There is no hardware device for ModemManager to handle.)
I know, and that is what I would expect to see on a such a system. Is your system dual boot (with Windows), and if so can you check operation with Windows perhaps?
