Security certificates

For some WAP services, such as banking services, you need a security certificate. Using the certificate
can help you to improve the security of connections between your phone and a WAP gateway or WAP
server, if the

Connection security

option is set to

On

.

You can download the certificate from a WAP page if the WAP service supports the use of security
certificates. After the download, you can view the certificate and then save or delete it. If you save the
certificate, it is added to the list of certificates in the phone.

You can only be sure that a WAP gateway or WAP server is the one it claims to be after its identity has
been checked against the corresponding certificate in the phone.
