enabled.

and retry.
After power up & PIN authentication the device reads all the SIM for a backup, hence SIM
access is inhibited (SIM is busy after the issue of the PIN or after power up if PIN request is
disabled) for a time varying from few seconds to about a minute, depending on the percentage
of written records in the SIM phonebook. If Phonebook commands are issued during this time
the device returns an error message. If this happens, the operations will start again later.
Due to the particular features of the FD storage, when selecting the FD storage the PIN2 must
be inserted or the FD facility must be enabled.
If +CPBS command reports +CME ERROR: 17 then enable the facility with command
+CLCK (see par. 3.1.1.2)
