HushSMS is a freeware application for Windows Mobile Pocket PC devices that can send silent SMS pings and class zero Flash SMS messages to any mobile phone. It also allows you to get return reciept or delivery confirmation for SMS sent.

“Silent Ping” enables you to sent a stealth message to another mobile device without the recipient knowing about it. The message is discarded on the owner’s phone and no trace exists. You will get back a message from the operator that your message has been delivered, proving that your message has been received, and thus you know that the recipient’s phone is switched on. Once you verifiy that the recipient’s phone is turned on, you can send a Class 0 Flash SMS that will be displayed on the recipient’s mobile screen without being stored.

Below are the options available in HushSMS for Windows Mobile:

+ Send a normal SMS
+ Send a class zero message (Flash-SMS)
+ Send a stealthy message

- To send a normal sms, leave the checkboxes for “Class 0″ and PING unchecked. If you want a return receipt, select the “Return Confirmation” checkbox.
- To send a class zero message enable the “Class 0″ checkbox and write the text of your message.
- To send a silent PING just enable the “PING” checkbox. There is no need to write anything in the Textbox, because the target phone will discard it anyway.
