Fi Ultra™ combines T-Mobile T-Satellite service with SpaceX’s Starlink, always-on GPS, and LTE connectivity in a single device — keeping dogs trackable no matter how far they roam.

Fi, the leader in smart pet technology, today announced the launch of Fi Ultra™, the world's first dog tracker powered by T-Satellite with Starlink, which leverages Low Earth Orbit satellites to keep cellular devices connected even outside terrestrial network coverage. Built for adventurous dogs and owners who live and explore beyond the reach of traditional networks, Fi Ultra delivers unprecedented GPS tracking and real-time connectivity, anywhere in the U.S.

Until now, no dog tracker has solved the fundamental problem of remote connectivity — the moment a dog ventures beyond a cell tower's reach, owners lose visibility. Fi Ultra changes that by integrating T-Satellite with Starlink directly into the device; Fi has engineered a solution that was previously unavailable in the consumer pet technology space, bringing satellite-grade connectivity to dog tracking for the first time.

"Fi Ultra has transformed what's possible for dog owners," said Jonathan Bensamoun, co-founder and CEO of Fi. "Our mission has always been to strengthen the human-animal connection via data, to give dogs more freedom while keeping them safe, and with the power of T-Satellite with Starlink behind Fi Ultra, that mission now extends to every corner of the country and soon, every corner of the world.”

Fi Ultra's T-Satellite with Starlink integration is a foundational design choice. Where other GPS trackers lose connectivity the moment cellular coverage ends, Fi Ultra stays connected via the same satellite network trusted by remote industries, emergency responders, and explorers worldwide. Whether a dog slips a fence in a rural area or a hike takes an unexpected turn deep into the backcountry, owners can receive real-time location updates regardless of cellular infrastructure. 

Key Features of Fi Ultra:

  • T-Satellite with Starlink GPS: Track a dog's location nearly anywhere in the US, including areas entirely without cellular coverage
  • Dual Band High-accuracy GPS: Deliver precise location data continuously, whether connected via satellite, LTE, Wi-Fi, or Bluetooth.
  • Automatic switching: Seamlessly connect to LTE when available and to T-Satellite with Starlink when cellular networks are out of reach — with no action required from the owner.
  • Real-time location updates: Deliver accurate, continuous location data whether the dog is in a city park or miles from the nearest cell tower.
  • Fi Callback™: A proprietary training system based on sound and vibration that uses no static electric shock to bring dogs back to their owners on command. 
  • Multi-day battery life: Operate multiple days on a single charge, supporting extended trips and remote exploration.
