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

) is encrypted.
However, the security indicator does not indicate that the data transmission
between the gateway and the content server (place where the requested resource
is saved) is secure. It is up to the service provider to secure the data transmission
between the gateway and the content server.
Important: Note that even if the use of certificates makes the risks involved in
remote connections and software installation considerably smaller, they must be
used correctly in order to benefit from increased security. The existence of a
certificate does not offer any protection by itself; the certificate manager must 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.
