I've had my Pinephone for some weeks now, and I'm trying to solve one important nagging issue.
The Broadband modem will just die and not come back up. I'm suspecting that it may be a weak or absent carrier signal but, I have very little to go on.
I'm not finding any mmcli commands that would allow me to reboot the modem.
When this happens, it's as if the device is gone, or has been completely unmounted and mmcli fails as there is no device and my only recourse is to reboot the system.
What would be the best approach to:
Here is the modem when it is actually healthy
The index seems to increase when waking up from suspend (Modem/0 -> Modem/1 -> Modem/2)
Thank your for looking into this, my first Pine64 post!

What would be the best approach to:
- Discover and remount the device if necessary
- Cycle the modem on if not active
