My new Thinkpad has a Quectel EM05-G modem. For some reason it refused connect, even though it showed up in Gnome settings on Ubuntu 22.10. I checked with “mmcli -m 0 and it said “sim missing” as its state.
After some Googling it appeared the modem ships in some kind of a locked state, so it only works in Windows. I checked with “mbimcli”:

1 2 3 |
$ sudo apt install libmbim-utils $ sudo mbimcli -p -d /dev/cdc-wdm0 --quectel-query-radio-state [/dev/cdc-wdm0] Radio state retrieved: 'fcc-locked' |
It was easy to unlock:

1 2 3 4 |
$ sudo mbimcli -p -d /dev/cdc-wdm0 --quectel-set-radio-state=on [/dev/cdc-wdm0] Successfully requested to enable radio $ sudo mbimcli -p -d /dev/cdc-wdm0 --quectel-query-radio-state [/dev/cdc-wdm0] Radio state retrieved: 'on' |
After this, Gnome was able to enable the mobile broadband connection without problem.
Hi, this was really a savr for me. I cannot connect to my network yet, but the modem is finally enabled on Thinkpad Z13 and Ubuntu 22!
Thanks so much 🙂
Does it work after suspend also?
Thanks a lot, this worked perfectly on a Thinkpad Z13 and ubuntu 22.04 LTS as well. After that it was easy to set up the mobile connection to my provider (O2 Germany) with the default Ubuntu settings. PIN was disabled beforehand.
Good blog really enjoy a lot
