(0.6.4) couldn't query SIM slots: QMI protocol error (94): 'NotSupported'

Hi, thanks for work on modem firmware.

@Biktorgj feel free to modify the issue title if you come up with something more meaningful / appropriate

system

pinephone, postmarketos-edge (phosh)

issue

I flashed 0.6.4 via the firmware-GUI, it worked for one day.

I was using the phone to navigate (https://github.com/rinigus/pure-maps, which uses geoclue), when at one point (i think i switched screen rotation at the same time, but i doubt this is related) the modem disappeared from phosh icon bar. I briefly investigated ad hoc, restartet eg25-manager and modemmanager services, entered sim pin and log similar to what's posted below.

I unpowered the modem (removed the battery), re-flashed the firmware, but to no avail.

Now, when entering sim pin, modemmanager says this:

$ (terminal0) logread -f | tee modemfail.log
$ (terminal1) sudo mmcli --sim=any --pin=XXXX
doas (user@pine64-pinephone) password: 
successfully sent PIN code to the SIM

$ cat modemfail.log

as it turned out, the "screen rotation" during navitagion session was related afterall ... i must have hit the "mobile network" icon next to "screen rotation", which then made phosh not use the modem, yet phosh asks for sim pin on boot.

sorry for the noise
