Check if modem is detected:
$ sudo dmesg |grep mhi
[ 0.917256] mhi-pci-generic 0000:04:00.0: BAR 0: assigned [mem 0xfd500000-0xfd500fff 64bit]

[ 0.918496] mhi mhi0: Power on setup success
[ 2.984935] mhi mhi0: Wait for device to enter SBL or Mission mode
Here we see that the radio state is "fcc-locked":
$ sudo apt-get install libmbim-utils
$ sudo mbimcli -d /dev/wwan0mbim0 -p -v --quectel-query-radio-state

Enabled the radio.

To make this permenant across reboots, sym-link the FCC-unlock scripts into the ModemManager directory.
$ sudo apt install network-manager
$ sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
Here we can see that there is a modem found but it has the eSIM slot set as the default, not the physical SIM:
