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.
