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.
To view or modify the security module settings, or to view a list of authority or user
certificates downloaded to your device, select

Important: 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.
