Phone Number Tracker - Mobile Number Locator Free is an application that provides a service to its users. The service is free and provides its users with the ability to track the location and telephone number of an unknown caller.
This app is working through GPS to track the current location and address of a phone or device with mobile phone location tracking. It will display the caller's current location on a map and the city area, state, country, and network operator of the phone number will be displayed. The service will also display the current time and date of the user's device.
This is very helpful in avoiding fraudulent callers. It also has a blocking function, so you can stop receiving unwanted calls.
