How to track a phone without them knowing?

The most effective way to track a phone without them knowing is using tracking software. It is a third-party application, service-based that anticipates a remote, without physical access, monitoring of the target phone. This kind of apps claims to be undetectable for the device’s owners and for identifying applications. Thus, from the very installation until the start, whatever a user does – SMS and calls monitoring, web activity tracking, GPS tracking, Viber or Snapchat messages viewing, etc. – they do it without others knowing about it.
