The current work around is to signal sim_inserted only when you know it =

is ready.  This is less than ideal since oFono can read non-PIN =

protected files from the SIM as soon as the SIM is inserted (e.g. ICCID, =

EFpl, etc).  However, the modem behavior is quite strange in this area.

I've not seen one that turns off the SIM.  After all, it would be pretty =

inconvenient not to read SMS messages or access contacts, or mess with =

MSISDN, or any other setting that is on the SIM.
