modem no carrier message

Yes, it is strange that certain topics like the Quectel modem which should be mentioned somewhere as a cookbook are completely absent and there is only a list of "working" operators with no reference on how you make Quectel to work.

The big picture is that every service has got some kind of command line tool, all the services are monitored and controlled by systemd and the communication between services and processes is achieved through D-Bus which can be inspected with programs like qdbus .

Though the ModemManager works simultaneously with ofono it is better to run only one of them so you keep ofono and disable ModemManager(if it is enabled) and then reboot

Code:
systemctl disable ModemManager

if you just stop the service it may not work well

In the previous link I gave, in the last chapter "GPRS & LTE configuration", the phone is configured for Koodo so you could just copy and paste the commands.

Here you can find some examples of how ofonoctl works

https://sr.ht/~martijnbraam/ofonoctl/

ofono list will show you where you are connected
ofono operators will show you all the available networks

for the time being you leave aside the minicom, mmcli which controls the unsused ModemManager and nmcli which controls the network interfaces  through the NetworkManager.

during the configuration you stop ofono too as you will see in the guide which is somehow involved because it uses the QMI interface of the modem through the D-Bus.

I believe your table too after giving the command ofono wan will be empty so you have to configure the context as it is done in the guide providing the network interface of the modem which is probably wwan0 and the right APN for Koodo.
