In BIOS I did only enable PXE.
Any Idea how to fix ?
Or do I need to switch to a specific Firmware.
@computersalat what was your previous firmware version before upgrade?
@computersalat I have just tested a Quectel EC25-E in an apu3 board (Debian 11, firmware 4.16.0.2, middle mPCIe slot). When I placed the SIM card in the left SIM slot (when looking from the front of the device) I had the same error in mmcli (sim-missing), but it started working when I moved the SIM card to the right slot.
Please check if moving the SIM card to the right slot helps.

@miczyg1 sadly I don't remember.
I tried randomly different BIOS versions. Neither legacy versions nor mainline version could fix it.
I tried different SIM without success. Used SIM works fine phone.

SIM is here:
J15 (mPCIe2) | USB, SIM1 | only LTE modules
That is the slot where the SIM worked before firmware update (left one)
I will try the other slot ...

so SLOT changed after firmware upgrade ... nice gadget.
@mkopec Thank you :-)
I tried it while the box was running even with a restart of ModemManger without success ... strange
Did I miss something ?
Glad it worked for you. Could be that an old firmware version had the SIM slots reversed. We'll check the documentation and see if it needs updating

Could be that the modem needs a reset after changing the SIM card, like some phones do.
