The Tractive GPS Pet Tracker works through an integrated GPS chip that continuously calculates its current location. This GPS data is sent to Tractive servers every few minutes, to enable pet owners to track their pets. An integrated, non-exchangeable SIM card enables the communication between the GPS device, Tractive Smartphone App and/or Tractive website. You can activate the LIVE Tracking feature anytime to see the movements of your pet in real-time, with updates every few seconds. To learn more, please watch the following video.
