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.
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.
There are three kinds of certificates:
server certificates, authority
certificates, and user certificates.
You may receive these certificates
from your service provider. Authority
certificates and user certificates may
also be saved in the security module
by the service provider.
To view the list of the authority or
user certificates downloaded into
your phone, select

is displayed during a
connection, if the data transmission
between the phone and the content
server is encrypted.
The security icon does not indicate
that the data transmission between
the gateway and the content server
(or place where the requested
resource is stored) is secure. The
service provider secures the data
transmission between the gateway
and the content server.
