At last I made it work on Plasma. I hope you can reproduce the result but also try to install a new image of Manjaro Plasma because the preinstalled had many problems.
I was based on the guide and I managed to do it completely through qdbus without the need to edit any files, so it is essential to understand the D-Bus technology. If qdbus is not installed open Discover and install the Qt QDBusViewer package.
As we have mentioned the applications and the services communicate through D-Bus so every app/service registers itself with a name and defines variables and operations that can be performed by talking to the app/service through D-Bus.
You can search the apps by typing qdbus and the services by typing
qdbus --system
So searching the system you'll find an entry org.ofono
With
qdbus --system org.ofono
you'll get the devices registered by ofono that is /bluetooth and /quectelqmi_0 that is a Quectel modem talking through the QMI interface with the name 0(zero), under each device you get some structures that can be configured like /quectelqmi_0/context1 and /quectelqmi_0/operators
qdbus --system org.ofono /quectelqmi_0/context1
will show you the possible operations that can be performed with the context. You may have more contexts, in fact I think you will need one more context for MMS so if it is not there you will have to create it
qdbus --system org.ofono /quectelqmi_0
you get ALL the operations that can be performed on the modem which are many and very interesting
What worked for me was to set up the context and reboot the phone because I wasn't able to activate the context by restarting services but I believe it can be done through qdbus because there are commands having to do with the activation of the context
In fact the only thing I needed to configure was the APN and the Authentication though I changed the Name too
So as it is done in the guide you first check the context
qdbus --system org.ofono /quectelqmi_0/context1 org.ofono.ConnectionContext.GetProperties
Then you set the variables
qdbus --system org.ofono /quectelqmi_0/context1 org.ofono.ConnectionContext.SetProperty AccessPointName attach.telus.com
qdbus --system org.ofono /quectelqmi_0/context1 org.ofono.ConnectionContext.SetProperty Authentication none
qdbus --system org.ofono /quectelqmi_0/context1 org.ofono.ConnectionContext.SetProperty Name Telus
The Protocol should be IP and the Type should be Internet, Username and Password should be empty, I don't know how many contexts you'll find and how many entries in the context and with what pre-configured values
After the reboot much more properties will appear like DNS, IP Address etc, then the NetworkManager will automatically configure the wwan0 interface so most of the tricks that are performed in the guide are not necessary, maybe all these steps were valid for PostmarketOS.
According to the guide you need one more context for the MMS with APN sp.koodo.com and Type mms
Try to do it and use the correct configuration from Koodo website and tell me if it works for you too.
I just figured out that the context is activated if you turn on and off one or two times the mobile data from the button in the panel that appears if you swipe downwards from the top of the screen, it seems that the button performs all the necessary operations to reset the mobile internet connection
