switch to 2G/3G?

[SchizoPinePhone225]

Plasma Mobile doesn't offer an option to set this, you need to use the command line:

For 2G only:
$ mmcli -m any --set-allowed-modes="2g"

For 3G only:
$ mmcli -m any --set-allowed-modes="3g"

For both:
$ mmcli -m any --set-allowed-modes="2g|3g" --set-preferred-mode="3g"

Thank you, mr duck man
