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.
Prolong battery life
Many features in your device increase the demand on
battery power and reduce the battery life time. 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. Turn Bluetooth technology off when you do
not need it.
•
If you have set
Packet data connection
to
When
available
in connection settings, and there is no
packet data coverage (GPRS), the device periodically
tries to establish a packet data connection. To prolong
the operating time of your device, select
Packet data
connection
>
When needed
.
•
If the signal strength of the cellular network varies
much in your area, your device must scan for the
available network repeatedly. This increases the
demand on battery power.
If the network mode is set to dual mode in the network
settings, the device searches for the 3G network. To
only use the GSM network, press
