To prevent hackers from doing harm to your Android Smartphone, this app will prompt you to use “SafeTelHandler” phone dialer when it detects a USSD code sent to your phone. Hackers use URL or NFC to inject USSD codes into your phone’s dialer without requiring you to press the button to activate. Hackers can deactivate your SIM card with these malicious USSD commands.
If your device is running Android version 3.0 (Gingerbread) or earlier, you should download this app to prevent USSD fraud. It is also recommended to backup your content from your phone frequently to prevent malicious activity.
To determine if your phone is vulnerable, perform the following steps:
1. Open your device’s browser and navigate to http://mobilephonesecurity.org/tel
2. If your device is vulnerable, you will see your IMEI displayed.
3. If you see *#06#, your device is secure and you don’t need to download this app.
Note: Once this app is installed onto your device, the app is hidden and therefore will not appear in the apps tray (no setup required). If you want to remove this app, go to SETTINGS> APPS, select “SafeTelHandler”, then click on the “UNINSTALL” button.
