Settings

Your device normally has MMS, GPRS, streaming, and
mobile internet settings automatically configured in the
device, 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.

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.
18
● 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.

Prolong battery life

Many features in your device increase the demand on
battery power and reduce the battery lifetime. To save
battery power, note the following:
● Features that use Bluetooth technology, or allowing
such features to run in the background while using
other features, increase the demand on battery power.
