Additional applications

There are various applications provided by Nokia and
different third-party software developers that help you do
more with your device. These applications are explained in
the guides that are available on the product support pages
of the Nokia website.

Settings

Your device normally has MMS, GPRS, streaming, and mobile
internet settings automatically configured, based on your
network service provider information. You may have settings
from your service providers already installed in your device,
or you may receive or request the settings from the network
service providers as a special message.
You can change the general settings in your device, such as
language, standby mode, display, and keypad lock settings.

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 to 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 UMTS mobile phones.
• 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.
