Public bug reported:

Configuration:
Ubuntu 22.04
Fibocom L860R+ Modem

Test steps:

1 Turn on the phone
2 Click Network Mode
3 Select 4g Only

Expected output:

4G can be set successfully.

Actual output:

Failed to setup 4g


analyze:

I checked the modem and when the modem is L860R+ it only has one allowed mode.
L860R+ does not support mbim2.0, so we only have one allowed mode here. When the modem has only one allowed mode, the setup mode is disabled. So we run into this error. Can we set the modes shown in NetworkMode to those provided by ModemManager
