● PIN2 code — This code (4 to 8 digits) is supplied with some SIM cards, and is
required to access some functions in your device.
● Lock code (also known as security code) — The lock code helps you to protect
your device against unauthorised use. The preset code is 12345. You can create
and change the code, and set the device to request the code. Keep the new code
secret and in a safe place separate from your device. If you forget the code and
your device is locked, your device will require service and additional charges may
apply. For more information, contact a Nokia Care point or your device dealer.
● Personal Unblocking Key (PUK) code and PUK2 code — These codes (8 digits) are
required to change a blocked PIN code or PIN2 code, respectively. If the codes
are not supplied with the SIM card, contact the operator whose SIM card is in
your device.
● UPUK code — This code (8 digits) is required to change a blocked UPIN code. If
the code is not supplied with the USIM card, contact the operator whose USIM
card is in your device.
