Can we locate a user via user's phone number in Android?

Question

Is it possible to locate a user via user\'s phone number in Android? If an SMS can be sent to the user then we can also retrieve or get to know the location of the user who we s

Answer 1

The answer is: you can't only through sms, i have tried that approach before.

You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.

I have looked through the 3 apps you have listed in your question:

1. The App uses WiFi and GPRS location service, quite the same approach as Google uses on the phone. phonesavvy maybe has a base station location database or uses a database retrieved e.g. from OpenStreetMap or some similar crowd-based project.
2. The app analyzes just the number for country code and city code. No location there.
3. Dito.
