Network services

To use the device you must have service

from a wireless service provider. Many of

the features require special network

features. These features are not available

on all networks; other networks may

require that you make specific

arrangements with your service provider

before you can use the network services.

Using network services involves

transmission of data. Check with your

service provider for details about fees in

your home network and when roaming on

other networks. Your service provider can

give you instructions and explain what

charges will apply. Some networks may

have limitations that affect how you can

use network services. For instance, some

networks may not support all language-

dependent characters and services.
Your service provider may have requested

that certain features be disabled or not

activated in your device. If so, these

features will not appear on your device

menu. Your device may also have a special

configuration such as changes in menu

names, menu order, and icons. Contact

your service provider for more

information.

Access codes

To set how your phone uses the access

codes and security settings, select

Menu

>

Settings

>

Security

>

Access

codes

.

The security code helps to protect

your phone against unauthorised use.

The preset code is 12345. You can

change the code and set the phone to

request the code. Some operations

require the security code regardless of

the settings, for example if you want

to restore the factory settings. Keep

the code secret and in a safe place

separate from your phone. If you

forget the code and your phone is

locked, your phone will require

service and additional charges may

apply. For more information, contact

a Nokia Care point or your phone

dealer.

The PIN (UPIN) code, supplied with the

SIM (USIM) card, helps to protect the

card against unauthorised use.

The PIN2 (UPIN2) code, supplied with

some SIM (USIM) cards, is required to

access certain services.

PUK (UPUK) and PUK2 (UPUK2) codes

may be supplied with the SIM (USIM)

card. If you enter the PIN code

incorrectly three times in succession,

you are asked for the PUK code. If the

codes are not supplied, contact your

service provider.

The barring password is required

when using the call barring service to

restrict calls to and from your phone

(network service).
