Well, maybe not much work, but probably a bit hard to get the logic right.

You may want to check what happens if you run
mm_base_modem_set_valid(FALSE) whenever the SIM is lost. That method
should flag the modem as invalid and reprobe from scratch, and that
will itself end up going into failed state.

Only with the handler that you expect; not with all unsolicited
message handlers.

That is equivalent to your step #2 above. When a modem starts without
SIM, it goes to Failed state right away. In your case, your Failed
state will be special, so that it really ends up keeping a port open
to monitor for the unsolicited messages you need.
