Access codes
If you forget any of the access codes, contact your service provider.
Personal identification number (PIN) code — This code protects your SIM card against
unauthorised use. The PIN code (4 - 8 digits) is usually supplied with the SIM card. After
three consecutive incorrect PIN code entries, the code is blocked, and you need the PUK
code to unblock it.
UPIN code — This code may be supplied with the USIM card. The USIM card is an enhanced
version of the SIM card and is supported by 3G mobile phones.
PIN2 code — This code (4 - 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. Additional charges may apply, and all the personal data in
your device may be deleted. 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 network service provider 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 network service provider whose USIM
card is in your device.
International Mobile Equipment Identity (IMEI) number — This number (15 or 17 digits)
is used to identify valid devices on the GSM network. Devices that are, for example,

stolen, can be blocked from accessing the network. The IMEI number for your device can
be found under the battery.
