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
