 Now press the button 'PING' and you will be taken to the screen below, through which you can select different types of PING SMS. Select the second option `Use Silent Ping (Type 0)` and send it to your own number. HushSMS will then send out a Silent SMS (but without the option of revealing the location of your phone) to your own number.
 
+##### Add your own SMS type detection
+
+Our app has been designed in a way that enables you to easily add your own detection mechanism. Enter the `ADVANCED USER SETTINGS` via the `Preferences` and add your own detection string like `incoming msg. Mti 0 ProtocolID 0 DCS 0x04 class -1` to the menu `Detection Strings` and restart SMS detection.
+
+If you found a new working string, please contact us for implementation.
