Note: If the digital signature icon does not appear, this means that there is a security breach, 
and you should not enter any personal data such as your signing PIN.
To sign the displayed text, select 
Sign
, after you have read all of the text. 
Note: The text may not fit within a single screen. Therefore, make sure to scroll through and 
read all of the text before signing.

Code error
 is displayed, and the phone asks you to key in the 
PIN code again. After the confirmation has been displayed, the digital signature icon will dissappear, 
and browsing continues. The WAP service may display a confirmation of your purchase.
Certificates
There are three kinds of certificates: 
• Server certificates
A server certificate is sent from the server to the phone and its validity is checked using the 
authority certificates stored in the phone or the security module. This way you can be certain that a 
WAP gateway or a WAP server is the one it claims to be.
You will see a note on the phone display if the identity of the WAP server or WAP gateway cannot 
be verified, if the WAP server or WAP gateway certificate is not authentic or if you do not have the 
right authority certificate in your phone.
• Authority certificates
Authority certificates are used by some WAP services, such as banking services, for checking 
signatures or server certificates or other authority certificates.
