20.1 Restricted Access to SIM Data after SIM PIN
Authentication
Users should be aware that when using a phonebook, SMS or Remote SAT command quickly after SIM PIN
authentication the SIM data may not yet be accessible, resulting in a short delay before the requested AT command
response is returned. This delay is due to the initial process of loading SIM data once after SIM PIN authentication.
The duration of loading SIM data is dependent on the SIM card used and may take a couple of seconds.
The "^SSIM READY" URC enabled with AT^SSET can be used to notify the user when the ME has finished reading
the SIM card and SIM data are accessible after SIM PIN authentication. Of course, all phonebook and SMS
commands may be issued before the URC is delivered. In this case the AT command response (for example the
complete phonebook) will appear after the delay mentioned above, but before the AT^SSET is displayed. See
example below.
Example:
AT^SSET=1 Activate the "^SSIM READY" URC.
OK
AT&W Store the presentation mode of the "^SSIM READY" URC to
the user profile.
OK
AT+CFUN=1,1 Restart the ME.

^SYSSTART The ME was restarted.
AT+CPIN Enter the SIM PIN.
OK
AT+CPBW=50,"[phone]",145,"Paul" Write a new phonebook record.
OK
^SSIM READY The URC now confirms that the ME has finished reading data
from the SIM.
AT+CPBR=50,50 Read the phonebook entered before.
+CPBR: 50,"[phone]",145,"Paul" The phonebook entry was properly saved.
