Government of india has allowed a relaxation in the SMS limitation. Now you can send 20 SMS per day .Earlier it was limited to 5 SMS per day and the decision had mixed response, people were finding it very difficult. The mobile companies faced huge revenue loss. Still the limitation is not fully removed. The limitation was implemented after North East residents living in different parts of the country started receiving threatening SMS-es. Because of the threat many moved back to their home states.
Now a days if you receive an SMS just be sure that you are so special to the person who sent that message.
