Installing Guix with mobile broadband connection

[MorphicResonance]

Watched video from systemcrafters' about installing Guix OS with wi-fi internet connection.
It became practice to create iso which requires internet access and do not include those with just mobile broadband connection.
Tried to find networkmanager , nmcli, mbim utilities ... anything to create mobile connection during the installation and found nothing. The only method of installation now is going to somebody with wifi and trying to install from there.

Think that is fine to generate an image which is focused on creating internet connection first because without it you can't install anything for a while. For supporting mobile broadband connection iso should include such packages as usb-modeswitch NetworkManager mobile-broadband-provider-info.
