Cheat codes always a part of fun but when they are applied in such a way that save your lots of money then it fills us with lots of enthusiasm, i saw some articles regarding sending free SMS but i never tried all that. But this is a technique which i tried and it works very well.
Whenever you will be in roaming then you need to change your message sending number and then see the magic of numbers.
Go to Message> Message setting>Text message>Message centres
You will see a message centre number as +919417399997 .
Just change the message centre number as +91941739999700.Save it.
Now whenevr you want to send a message you need to select the new message centre number to send a message. Remember to off delievery report,sometimes charges for delievery reports are deducted.
Now by using this trick you can send unlimited Free SMS all over India. Unfortunately,this code only works when you are in roaming and you can not send free SMS worldwide.
