+CPIN2 – Enter PIN2
Description:
This specific command is used to validate the PIN2 code (CHV2), or to validate the
PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code. Of course, the +CPIN
command allows PIN2 or PUK2 codes to be validated, but only when the last command
executed resulted in PIN2 authentication failure.
PIN2 length is between 4 and 8 digits, PUK2 length is 8 digits only.
Syntax:
AT+CPIN2=
AT+CPIN2=
After 3 unsuccessful attempts, PUK2 will then be required. PUK2 validation forces the
user to enter a new PIN2 code as a second parameter and this will be the new PIN2
code if PUK1 validation succeeds. The application therefore uses the “AT+CPIN2=
To find out which code must be entered (or not), the following query command can be
used:
AT+CPIN2?
Response Syntax:
+CPIN2: READY
No PIN2 is needed
+CPIN2: SIM PIN2
PIN2 is required
+CPIN2: SIM PUK2
PUK2 is required
+CME ERROR:
Absent (10) etc...
