2.5.2.3 Provide SIM PIN (only if required see point 2.5.2.2)
•
send command AT+CPIN=****<cr>
where **** stands for the SIM PIN code (e.g. 1234)
• wait for response:
Response Reason Action
OK SIM PIN was correct Proceed ahead
ERROR the PIN code inserted is not
correct
Retry from par. 2.5.2.2
NOTE: When receiving the ERROR message, repeat
Query SIM presence and status since after
3 failed attempts SIM PIN is not anymore requested, but SIM PUK is requested instead, hence
you may need to go through procedure
2.5.2.4
2.5.2.4 Provide SIM PUK (only if required see par. 2.5.2.2)
•
send command AT+CPIN=*******,<newpin><cr>
where ******* stands for the SIM PUK code (e.g. 12345678) and <newpin> (e.g. 1234) will replace the
old pin in the SIM.
• wait for response:
Response Reason Action
OK SIM PUK was correct Proceed ahead
ERROR the SIM PUK code inserted is
not correct
Retry from par. 2.5.2.4
TIP: When receiving the ERROR message, be careful to check if the SIM PUK is correct before
retrying, since after 10 failed attempts to provide the SIM PUK the SIM Card will lock and will
not be usable anymore.
