service provider.
To view or change the security module settings, or to view a list of authority or user
certificates downloaded to your phone, select Menu > Settings > Security >
Security module settings, Authority certificates, or User certificates.
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.
