The website Phone-Track allows users to track the position of a phone. Phone-Track claims to use the phone number associated to a phone to locate it using satellite technology as of 2015. This service is used to track people and to find the location of a lost or stolen phone.
The Phone-Track service is globally available and compatible with many smartphone devices that have GPS, including iPhone and Android devices. Phone-Track even claims to be able to locate a phone when it is turned off, using their reverse-lookup technology. The site is free to use, but requires its users to complete online surveys before viewing the final report.
