Let's collect findings to get the Modem running, then write an article on the wiki.
I will update with my state of progress, so far:
FCC unlock - seems to work
nmcli radios - without FCC unlock - gives me this response
WIFI-HW WIFI WWAN-HW WWAN
enabled disabled missing enabled
mmcli -L
No modems were found
lspci -nn
08:00.0 Wireless controller [0d40]: Intel Corporation XMM7560 LTE Advanced Pro Modem [8086:7560] (rev 01)
rfkill
ID TYPE DEVICE SOFT HARD
1 wwan tpacpi_wwan_sw unblocked unblocked
FCC unlock - needs to be done after every boot
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
enabling the modem
mmcli --modem=0 --enable
or if pin isn't disabled
mmcli --modem=0 --sim=0 --pin=****
checking the state again
mmcli --modem=0 --sim=0
results in something like this

trying to enable the modem
sudo mmcli --modem=0 --enable
still gives an Error - any info what "Invalid transition" means welcome
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Invalid transition'
using simple-connect to connect to APN
mmcli -m 0 --simple-connect='apn=YOUR.4G.PROVIDER,ip-type=ipv4v6'
getting the bearer ?? not shure about the process here
sudo mmcli --modem=0 --bearer=0
results in this Error - probably beacause the modem is not enabled correctly ??
error: couldn't find bearer at '/org/freedesktop/ModemManager1/Bearer/0': 'not found in any modem'
From here everything is mostly documented in this Article
...
Please comment your findings, I will check an put them in the link list
Thanks in advance for any help!

The forum isn't the correct place for this.
Please use the relevant Talk pages on the wiki for gathering suggestions.

Thanks @esemeniuc,
I will add the links to the list.
Also I am finishing the structured configuration notes as soon as I have a couple of minutes.
A script is probably needed to do the enabling of the modem, unblocking the radio, and maybe do the FCC unlock after each reboot or wake-up from suspend. So there are a lot of things to cause the error.
