108 Access codes

Access codes
PIN code — This code protects your SIM card against unauthorised use. The PIN code (4
- 8 digits) is usually supplied with the SIM card.
PIN2 code — This code (4 - 8 digits) is supplied with some SIM cards, and is required to
access some functions in your device.
If you forget an access code, contact the network service provider whose SIM card is in
your device. After three consecutive incorrect PIN or PIN2 code entries, the code is
blocked, and you need the PUK code to unblock it.
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.
IMEI number — This number (15 or 17 digits) is used to identify valid devices in the GSM
network. Devices that are, for example, stolen, can be blocked from accessing the
network. The IMEI number for your device can be found under the battery.
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.
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.

Troubleshooting

Restore original settings

If your device is not working properly, you can reset some settings to their original
values.
1 End all active calls and connections.
2 Select Menu
Restore.
3 Enter the lock code.
This does not affect documents or files stored on your device.
After restoring the original settings, the device switches off, and then on again. This
may take longer than usual.
