No modems were found: No mobile data, no 2G

Hello

I'm unable to bring up the modem, restarting eg25-manager has no effect, I have no longer any prompt to enter my PIN code. This problem appeared last week on my very first Pinephone which is two years old, the operating system is up-to-date (bookworm). I'm completely stuck as my second Pinephone doesn't work too

I tried:
sudo systemctl restart eg25-manager
mmcli -S

Do you have a suggestion?

i'm testing mobian as of now and i didn't notice anything weird (in regards of modem). although, i don't use sim pin codes.

let's start with these, what following commands tell.

Code:

##
$ mmcli -L
##
$ lsusb

mmcli -L printed "No modems were found". As the touchscreen is broken, I preferred using my second Pinephone, I replaced Manjaro KDE by Mobian, I installed Tow-Boot and I used mobian-installer-pinephone-phosh-20221120.img (very important as the very latest installer doesn't work). Everything works like a charm now. I'll try lsusb by curiosity one day if my first broken Pinephone works a bit soon.
