8.1.3 +CPIN, Enter PIN for Unlocking SIM or Enter PUK for
Unblocking SIM
This command unlocks the SIM card when the proper SIM PIN is provided and unblocks the SIM card
when the proper SIM PUK is provided.
The SIM card is unlocked only once the provided pin is verified as the SIM PIN. If the required PIN
(determined by the error code returned from the requested operation or the Read command) is SIM PUK
or SIM PUK2, the second pin is required. This second pin, <newpin>, is used to replace the old pin in the
SIM card. When entering the pin, a <new pin> is not required.
A SIM card related error is returned if an AT command operation is unsuccessful due to a SIM card
problem. The following table shows the SIM card errors.
