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

[Stelling2 Carsten]

Hi,

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.

Carsten
