Background initialisation
After a valid PIN entry, many SIM user data information are loaded
in the modem memory (Phonebooks, SMS status…). This operation
can last a long time when reading huge phonebooks.
The AT+CPIN? command answers just after verification of the PIN.
User Data are loaded in background after the PIN checking.
This means, that some data of the SIM may not be available
straight after the "OK" (if PIN is valid) of the PIN Entry function was
received by the TE. Data that may be affected are particularly the
phonebook's entries.
So that any access to phonebooks features will then be refused by
the following error message "
+CME ERROR:
515" or
"
+CMS ERROR:
515" meaning "please wait, service is not available,
initialisation in progress".
Also this kind of answer may be returned by the modem in several
circumstances:
•
when trying to execute another AT command before the
previous one was executed to the end.
•
when swapping from (or to) ADN to (or from) FDN and
trying to immediately read the concerned phonebook;
•
when giving the +CPIN? command (SIM Status) just after a
SIM insertion and before the modem could execute a valid
SIM Card logical session.
