If you want to find the location of a caller or the caller's number, you can use the free number location app for Android. The application will give you all the information you need about the caller, such as the country and the city. You can use the app to find out who is calling you, even if you are on a call right now.

The application is very easy to use and will not take up much of your time. The application does not need any other hardware or software, so you can use it on any Android device. The only thing you need is your phone number.
