Tools When calls are limited to closed user groups, calls may be possible to the official emergency number programmed into your device. Confirm SIM services-You can set the device to display confirmation messages when you are using a SIM card service (network service). Glossary of PIN and lock codes If you forget any of these 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 PIN code is blocked, and you need to unblock it before you can use the SIM card again. See the information about the PUK code in this section. 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. The UPIN code protects the USIM card against unauthorized use. 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)-This code (5 digits) can be used to lock the device to avoid unauthorized use. The factory setting for the lock code is 12345. To avoid unauthorized use of your device, change the lock code. Keep the new code secret and in a safe place separate from your device. 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. Certificate management Digital certificates do not guarantee safety; they are used to verify the origin of software. Glossary: Digital certificates are used to verify the origin of the XHTML or WML pages and installed software. However, they can only be trusted if the origin of the certificate is known to be authentic. In the certificate management main view, you can see a list of authority certificates that are stored in your device. Press to see a list of personal certificates, if available. Digital certificates should be used if you want to connect to an online bank or another site or remote server for Copyright © 2005 Nokia. All rights reserved. 99
