Abstract: Lots of Applications are developed to track a Smart phone but still it is a major concern. User has to manually report to the customer care to block the IMEI Number of the lost Phone. So that, Android Application is deployed with initial registration of Alternative Mobile numbers. An Application which is deployed in the mobile devices can be able to Track the current location of the device. If the robber changes the SIM card, immediately then location details are sent to the alternative Phone number of the original User. In this paper, both the logic of tracking the Theft Phone with SIM Card & Theft Phone with changed SIM Card is tracked continuously. The registered mobile numbers can get the SMS alert from the Theft Mobile. This process is reworked continuously to track the android mobile phone.
