Some SIM cards do not allow the PIN code request to be turned off.

Fixed dialling to restrict your outgoing calls to selected phone numbers if this function is supported
by your SIM card. The PIN2 code is required.
Closed user group. Closed user group is a network service that specifies the group of people whom
you can call and who can call you. For more information contact your network operator or service
provider.
Security level. Select Phone and the phone will ask for the security code whenever a new SIM card is
inserted into the phone.
Select Memory and the phone will ask for the security code whenever you want to select the
phones internal memory or to copy from one memory to another. See Selecting the phone book

Change of access codes and you can change security code, PIN code; PIN2 code or barring

Note that you should avoid using access codes similar to the emergency numbers, such as 112, to
prevent accidental dialling of the emergency number.
