Is the module integrated in the laptop? I wonder why you get the SIM
not detected, which is what the modem is reporting:

ModemManager[2508]: <debug> [1485208245.529656] [mm-iface-modem.c:266]
load_unlock_required_ready(): Couldn't check if unlock required: 'SIM
not inserted'
ModemManager[2508]: <warn>  [1485208245.529956]
[mm-broadband-modem.c:9541] iface_modem_initialize_ready(): Modem
couldn't be initialized: Couldn't check unlock status: SIM not
inserted

What's the output of:

$ sudo qmicli -d /dev/cdc-wdm0 --device-open-mbim --dms-uim-get-pin-status
$ sudo qmicli -d /dev/cdc-wdm0 --device-open-mbim --uim-get-card-status
