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.

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.
