How to send a message that gives you delivery report when user reads that message..????

This is simple trick. Some time we send message to our friends but we are unable to know when he or she reads it. Now I will tell you a trick.
Go to create new message. When you are in message editor simply type *0#
and then type your message. Then add a contact and send your message. Don’t worry your friend don’t see *0# .
And as he open the message a delivery reports automatically send to your phone. And you know when he or she reads the message.
Done!!
