Re: Surely the 4G/Simm provides good tracking anyway?
To identify a phone by its signal, you need to get force the phone to switch down to 2G because anything higher than that is encrypted. Sure the phone company can do this but if you want to build a system yourself then you have to deploy a base station which is illegal in some countries. BTW systems to do this are VERY expensive but WiFi tracking system are very cheap and are legal!
