Example:
You enter the correct PIN2:
Enter: AT+CPIN2=“1234“
GSM module: OK
You enter an incorrect PIN2:
Enter: AT+CPIN2=“1234“
GSM module: +CME: ERROR: WRONG PASSWORD
This command allows you to change the password. Since more than one password will
be available for future uses, you must specify the name of the password upon entering
it.
Example:
Enter: AT+CPWD=? Requests the list of passwords (SC = SIM,
PS = device code, P2 = PIN2)
GSM module: +CPWD: (“SC,8“,“PS,8“, “P2,8“)
OK
Enter: AT+CPWD= “sc“,“1234“,“4321“
GSM module: OK Password was successfully changed.
The following result code is returned if the old PIN you enter is incorrect:
Enter: AT+CPWD= “sc“,“0123“,“4321“
GSM module: +CME ERROR: INCORRECT PASSWORD
The password was not changed because the
old PIN was incorrect.

rently include the PIN, device code and PIN2.

This command instructs the GSM module to change the
relevant password. When changing the password, you
must enter both the old and new password. This ensures
that changes can be made only if access is authorized.
