PIN2 code is also 4 to 8 digits long and is supplied with some SIM cards, and is required to access certain services.

  • If you enter any of the above PIN codes incorrectly three consecutive times, you need corresponding PUK codes to unlock them. Read more about PUK codes below.

PUK (Personal Unblocking Key) codes:

PUK code is 8 digits long and is required to change a blocked PIN code.

PUK2 code is required to change a blocked PIN2 code.

The PUK codes are also provided by your network operator.

Restriction code / Restriction password:

The restriction code or restriction password may be required when using some network services, such as call restriction service. Note that not all network operators support such service.

If your device display “Enter restriction code” when you insert a new SIM card, it means that your device has been locked to use a certain operator’s network and it does not accept SIM cards from other operators.

Contact your network operator for assistance.

Other PIN codes:

The module PIN is required to access the information in the security module of your SIM card.

The signing PIN may be required for the digital signature.

Lock code / Security code / Password:

These codes protect your phone from unauthorised use.

The default lock code or security code supplied with the phone is usually 12345. For Nokia N9 and Lumia devices there are no default codes. It is recommended to specify the code of your own. The instruction on how to change the code is provided in the user guide.

If you get error notifications after entering the code too many times incorrectly, reboot the phone and wait for 15 minutes, then try again.

If the problem persists, contact your local Nokia Care Point. The contact information can be found from your local Nokia support web pages.

PAC (porting authorisation code) code:

This code is used by some mobile network operators to facilitate mobile number portability. The code allows you to transfer your existing mobile phone number from one mobile phone network provider to another mobile phone provider so that if you change mobile phone networks you do not have to give everyone a new number. You can keep your existing mobile phone number.


If you do not know or forget any of these codes above, always contact your network operator. Keep all the codes in a safe place separate from your phone.
