The Police have two methods for tracking your phone when it’s stolen, they can use your phone number or your IMEI number. The demonstrated attack allowed the capture of the cell phone’s IMSI number within seconds as soon as the user came in range of the network. This has been used by law enforcement agencies to track suspects and find missing people. This will ensure that your Wi-Fi call cannot be traced and that you will have a secure connection. When making a Wi-Fi call you are trusting that the Wi-Fi network you are connected to is secure and that there is the relevant safety measure in place to ensure your call does not get traced or tampered with in any way.
