ATTENTION
Be careful when entering the PIN codes.
After 3 unsuccessful attempts at entering the PIN, you will need to use the PUK to proceed. PUK validation
forces the user to enter a new PIN code as a second parameter, and this will be the new PIN code if PUK
validation succeeds. CHV1 will be enabled if PUK1 is correct. Therefore, the application uses the following
command:
AT+CPIN=<PUK>,<NewPIN>
Note that users must apply for PUK codes from the mobile service provider.
