Certificates

Certificates are used for network security exchange.
There are two types of certificates: the user's certificate and the trusted certificate.
The user's certificate is sent by the phone to the contacted WAP™ service. It is a proof of the
user's identity.
The trusted certificate is sent by the contacted WAP™ site to the phone. It guarantees the
WAP™ site is authentic and you have the right certificate in your phone. If you do not have the
right certificate the site identity cannot be checked (certificates can then be downloaded from
a WAP™ page).
To display a certificate,

Press the [Menu/T9] key. Select Settings.
