If you forget any of the access codes, contact your
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.
