In the first run MM detects that the modem is SIM-PIN locked, and once
it gets exported to DBus you're calling Simple.Connect() including the
PIN number in the connection details, so the modem gets unlocked and
connected.

In the second run MM also detects that the modem is SIM-PIN locked,
and once it gets exported to DBus I see no logs saying that any
Simple.Connect() was performed.

Is this with NetworkManager? If so, how are you requesting the
connection to be started?
