Settings; Access Codes; Prolong Battery Life - Nokia N79 Guia Del Usuario

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 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. 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.
