If the Police have your mobile phone number then I understand they can track your mobile phone. Now, I understand the mobile phone number is linked to the sim card but if you simply change the sim card does that stop the Police from tracking you? Because I also understand that all mobile phones have a IMEI number.
Can the fact they had the sim card mobile number while inserted into a mobile phone give them access to that number so even if you change the sim card, they can track the mobile phone no matter what sim card is inserted? Hence, if so, is a new mobile phone and sim card is the only option ?
