So my question is: Who does decide between qmi-wwan or ppp?
ModemManager does, based on device discovery. So it's likely that the
version of ModemManager that you typed as "mm??" isn't able to correctly
recognize the modem as a QMI one. That is either a ModemManager
problem, a kernel driver problem, or a "modeswitch" problem (where the
device is not told to come up in the right mode by usb_modeswitch, if
the modem requires that).
If you can add "--debug" to the ModemManager service arguments (through
either systemd, dbus autostart, or whatever runs MM on your system) them
we could get more info.
All software seems "new":
NetworkManager 1.0.6
ModemManager 1.4.10
qmicli 1.12.6 libqmi-glib.so1.3.0
usb_modeswitch 2.2.5

But there no devices wwan0 (or the udev-renamed kind)
and no /dev/cdc_wdm
the kernel module qmi_wwan is loaded.
I know the list doesn't support particular linux-distros, but could you
me or the manjaro-people a further hint?
