I know quite a bit about tracking cell phones that are network contract phones. I need to know if it is possible to track a prepaid cell phone. I have heard that there are apps you can down load to a prepaid and there is a pay site that can then track the app on the phone. Has anyone had any experience with this technology? Does it work as advertised? Is there other technologies I can employ to tract the location of a person or vehicle that is commercially available that can be used? Thanks in advanced any technical advice will be greatly appreciated.
