Certificates
There are three kinds of certificates; server certificates, authority certificates, and 
user certificates. Authority certificates can either be saved in the security module 
by the SIM card issuer or service provider, or they can be downloaded from a WAP 
page and saved in the phone’s memory. User certificates are saved in the security 
module by the SIM card issuer or the service provider. Server certificates are not 
saved.
• Server certificates
A server certificate is sent from the WAP server to the phone and its validity is 
checked using the authority certificates saved on the phone or in the security 
module. The phone tells you when the identity of the WAP server or WAP 
gateway cannot be verified, when the WAP server or WAP gateway certificate 
is not authentic and when you do not have the correct authority certificate on 
your phone.
The security indicator 
is displayed during a WAP connection if the data 
transmission between the phone and the WAP gateway or WAP server 
(identified by the 
IP address
 in the 
Edit active service settings
 is encrypted.
