Nov 29 10:00:03 6074285570 ModemManager[2055]: <info>  Creating modem
with plugin 'Generic' and '6' ports

This is likely an MBIM-capable Ericsson module; which we anyway don't
have it listed in the Ericsson-MBM whitelist, so it won't work properly
not even with AT commands.

Can you try to add the following line to the
"plugins/mbm/77-mm-ericsson-mbm.rules" file?

ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="193e",
ENV{ID_MM_ERICSSON_MBM}="1"


Also, trying with libmbim installed and MM recompiled with MBIM support
would be nice.
