Modem disabled, can't enable: Invalid transition
I have a new PinePhone, with a new SIM card, and the modem won't connect. The carrier assures me the SIM card is activated. (I went through 5 or 6 support people and I believe the last one actually knew what he was doing.)

The phone came with Manjaro installed. I'm looking at the Cellular Network section of the Settings app, sometimes I see a SIM 1, sometimes SIM 2, I've even seen SIM 4. If I select SIM 1 (or whatever number) and go to Select Network Operator it says "Current operator: none". If I hit the Scan For Networks button, I get one of these messages:

  Scanning networks failed: Object does not exist at path "/org/freedesktop/ModemManager1/Modem/1"
  Scanning networks failed: Cannot scan networks: not enabled yet

I suppose the first one is because the number keeps changing.

When I hit View Modem Details, I see an Enable Modem button and a Force Modem Restart button. I have tried both of those a few times, and they don't do anything as far as I can tell. I have rebooted the phone a few times also.

I suspected a command line equivalent of the Enable Modem button might give me better feedback, so I tried this: `mmcli -m 2 -e` and it said

  error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Invalid transition'

And that, I guess, is the root problem. But I don't know what an invalid transition is so I can't troubleshoot any further without a hint.
