How to encrypt the SMS of Sony Ericsson K750c?

All I know is that there is a software that can encrypt files. I don't know if SMS can be used. You can try.

Before using the software, please explain that .. the left key is the OK key on the left, and the navigation key is the remote sensing or middle key [W550]. ..

Download Opera Mini and decompress it. After decompression, upload Opera Mini.jar in the folder directly to your mobile phone ~

Start Opera Mini, and press the left key of the mobile phone to bring up the menu. Select "Management → System Maintenance → File Management" from the menu. When the software prompts "Allow the application to read user data", just select "Yes" ... [Note: it will pop up many times, especially when opening file information, it is troublesome to keep pressing OK ~ Crab only tries to modify it once in JAVA permissions.

In the next menu, select the file to be encrypted, and then select "More → Rename" to modify the file extension at will. This way, the mobile phone can't open the file, so as to achieve the purpose of encryption, and then change it back when you use it yourself ~

If you don't want others to open or delete this file, select "More → Info [always click OK ~]" and select "Read Only" in "Properties" ~

According to reports, using Opera Mini can delete protected pictures, ringtones and videos in mobile phones ~ [Java programs and themes can't] ... The operation steps are also very simple. Enter drive C, select the picture to delete, and delete it after removing the "read-only" attribute.
