The Guardian app is a new protection system for Symbian S60 devices. Every time you turn on your mobile phone, the Guardian program continues to monitor the authenticity of the inserted SIM card.
If the proof of the authenticity fails, the application sends a message to a specific number to give you a notification. In addition, it supports remote control function. So you can delete your messages, video, audio or photos in case of loss or theft of your mobile device.

Supported operating system: S60 2nd Edition.
