How to encrypt the SMS of Nokia S6700?

I use version 8. 19 of the mobile phone wizard, which can completely encrypt short messages and put the phone number of the person who wants to encrypt in the "Baby List", so that the received short messages will not be seen in the normal inbox, and you need to enter a password to view it in the mobile phone wizard software, and the software itself is a hidden version, and no one knows that you have installed this software. This version of official website is lelebox, and the signed trial version does not need a certificate.

Other encryption aspects can encrypt all applications such as call records, files and games.
