There are many ways available to give a mobile user prank calls and cause distress by it. The user can be student or anyone certainly the Prank Calls are not welcome by anyone except the persons making them or promoting them. I want to put a restrictive measure for making mobile user able to decide over his calls and avoid prank calls. Otherwise, people who are receiving prank calls have to call up Customer Care Services and it’s having limitations these days to call them 3 times a day. If the prank call receiver calls in distress more than 3 times probably he looses his Service to call to Call to Customer Care from his SIM. The email reply by Customer Care comes within 48 Hrs or even a delayed responses are received sometimes. Prank calls may come from different numbers at different times so person can’t predict no to block always and use call manager facility provided to him becomes inefficient. So, the available ways don’t solve the problem of person meeting harassment by prank calls. This is more serious offense in some cases leads to serious losses. So, we propose the simple solutions to save the innocent persons being targeted by the prank calls by using prefixes and number formats. The formats needs to meet some change and the verification process is added to ensure type of call and signal it to the user on screen.
