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. See "Settings," p. 153.

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 unauthorized 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

help

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

unauthorized use. 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.
