Security module
The security module can contain certificates as well as private and public 
keys. The security module is to improve security services for functions 
requiring browser connection, and allows you to use a digital signature. 
The certificates are saved in the security module by the service provider.
In the Services menu, select Settings, Security settings and Security 
module settings. Select
• Security module details to view the security module’s title, status, 
manufacturer and serial number.
• Module PIN request and On to set the phone to ask for the module PIN 
when using services provided by the security module.
• Change module PIN to change the module PIN, if allowed by the 
security module.
Certificates
The phone supports three kinds of certificates: server certificates, 
authority certificates and user certificates. You may receive these 
certificates from a service provider. Authority certificates and user 
certificates may also be saved in the security module by the service 
provider. For details and availability, contact your service provider.
When using a server certificate, the security indicator   is displayed 
during a connection, if the data transmission between the phone and the 
gateway (identified by the IP address in the Edit active service settings) is 
encrypted.
