Browser security
Security features may be required for some services, such as online
banking or 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 may contain certificates as well as
private and public keys. The certificates are saved in the security module
by the service provider.

manufacturer, and serial number.
•Module PIN request to set the phone to ask for the module PIN when

•Change module PIN to change the module PIN, if allowed by the
