A) PIN MANAGEMENT
Due to security reasons, usually SIM cards require the insertion of PIN code. With Pocket
GSM you can insert the PIN code through the AT+CPIN command.
If your application has other security systems, you can disable the PIN request using a
mobile phone.
Examples:
Command: AT+CPIN?
Answer: ERROR
Answer: +CPIN: READY
Answer: +CPIN: SIM PIN
Answer: +CPIN: SIM PUK
Answer: +CPIN: SIM PIN2
In case the PIN code is not present, it must be inserted before using the SIM card:
Command: AT+CPIN=4321
Answer: OK
Answer: ERROR
Attention: remember that if the PIN code is wrongly inserted for three times, the SIM card will block. To
unblock it you must insert the PUK code.
