Well this trick works with Airtel User only but you may try with your service provider also. In this trick you can stay away from unwanted calls (they will find it switch off) while its on. For using this trick first you have to activate RMCA that is Reverse Missed Call Alerts for that Airtel Pre-Paid customers have to send SMS "RMCA" to 55696 to get this service activated for Post Paid customers get the information form your customer service number. (plz check with your customer care for activating RMCA, SMS will be charged at 3 Rs. , for this service you will be charged at rs 10-15 per month)After your service activated wat you have to do is just Activate "DIVERT ALL CALLS" to +91568 thats it.Now if somebody calls you he/she will find your phone switched off but your phone is switched on
