How to spy on an Android phone without installing software?

If you need to spy on an Android phone, you can use:

  1. Free online services that track only GPS location of the target phones (Google’s Find My Phone);
  2. The services of mobile providers (AT&T) that allow tracking GPS and SMS;
  3. Tracking applications that allow spying on any device remotely.

The choice depends on the user’s specific needs. For example, if they need to spy on someone’s current whereabouts, then the first two ways might be ways out. If they need Viber messages or Instagram ones, then a tracking application is the only solution.

Note! Google online services and mobile providers do not require the installation, meantime a tracking application must be installed on the target device.
