I want to have modem manager being enabled/working on 1 specified sim-card. Basically an whitelisting option for sim-cards will do the trick.
I already looked at the following: https://www.freedesktop.org/software/ModemManager/man/1.0.0/mmcli.8.html but I couldnt find it. I understand that there is only an option for whitelisting devices, not for sim-cards.
If I could get the current sim-number somewhere, then maybe I can create some whitelisting logic by myself. But also getting the current sim-number that is in use/available seems hard to get.
Thanks in advance.
Working on: linux/debian OS
