this function name is weird. Calling it sim_inserted_timeout_callback or
so would be a lot clearer.

So I rather prefer (struct ofono_modem *modem, int status) here. Or even
better just do (struct telit_data *data, int status) since you are not
really dealing with ofono_modem here anyway.
If you wanna keep ofono_modem, because that is what you have as
user_data in the qss_notify, then that is fine with me.

Why are you not handling any of case 2 or 3. Are they not also mean that
SIM is inserted. Or do they always are followed by case 1.

You can just leave the default statement out. Not really needed here
anyway.

You forgot the extra space between status, modem.

If I am not mistaken, then the set_powered(FALSE) call is missing here.
Did you test this code path?

I remember that I mentioned this before. This is not needed. The disable
callback will never be called if enabling never succeeded.
