Trax Play is the world’s smallest and lightest live GPS tracker for children and pets. With a size of only 55x38x10mm, it’s incredible that this little device can listen to 4-14 satellites, and send its position, speed and direction through GSM networks directly to your smartphone. Trax Play currently works in 39 countries. Note: Trax Play requires a service plan for cellular connection, for as low as $4.00/mo. Data plans can be selected and purchased via the app or our website.
