Viewing certificate details - checking authenticity
You can only be sure of the correct identity of a browser gateway or a
server when the signature and the period of validity of a browser gateway
or server certificate have been checked.
You will be notified on the phone’s display
• if the identity of the browser server or gateway is not authentic or
• if you do not have the correct security certificate in your phone.

Certificate details . When you open certificate details, Certificate
management checks the validity of the certificate and one of the
following notes may appear:
• Certificate not trusted - You have not set any application to use the
certificate. For more information, see “Change the trust settings of an

phone are correct.
