Browser security
Security features may be required for some services, such as banking services or online shopping. For such connections you
need security certificates and possibly a security module, which may be available on your SIM card. For more information,
contact your service provider.
Security module
The security module improves security services for applications requiring a browser connection, and allows you to use a
digital signature. The security module can contain certificates as well as private and public keys. The certificates are saved in
the security module by the service provider.
To change the security module settings, press Menu, and select Services → Settings → Security settings → Security module
settings.

• Change signing PIN—to change a signing PIN. Select the signing PIN that you want to change. Enter the current PIN code,

contain correct, authentic, or trusted certificates for increased security to be available. Certificates have a
restricted lifetime. If Expired certificate or Certificate not valid yet is shown even if the certificate should be
valid, check that the current date and time in your device are correct.
Before changing any certificate settings, you must make sure that you really trust the owner of the certificate and that the
certificate really belongs to the listed owner.
There are three kinds of certificates: server certificates, authority certificates, and user certificates.
• Server certificates are for creating a connection with improved security to the content server. The phone receives the
server certificate from the content server before the connection is established and its validity is checked using the
authority certificates saved in the phone. Server certificates are not saved. The security icon
