Set allowed mode to 2G, 3G, 4G not working

[Aleksander Morgado]

Hey,

> I'm using ModemManager 1.10.0, and libmbim 1.18.0 in conjunction with Telit LE910-EU V2.
> It all works fine, but I'm not able to set the preferred GSM mode or access technology.
> I'm confused by this error message "Cannot change modes: only one combination supported', because only one mode is given.
>
> Thank you for your help.

Totally untested!
