Set the default SIM slot

[MobiStick]

Hi all,

Is there a way to set a default SIM slot?

I have a OpenWrt device with an eUICC (slot 1) and UICC-slot (slot 2). The eUICC is always selected as the active slot on boot (but does not work). Switching the slot generally works, but no connection can be established: "device not ready". The same device without the eUICC works just fine with the same settings.

My guess is that all slots are tried starting at 1 and the first one responding is selected as the primary. And because the eUICC is in slot 1 it always wins. Is that true and can i change this behavior?

ModemManager 1.20.6
mmcli 1.20.6
qmicli 1.34.0

Best,
Mobi
