TAMPA, Fla. — Pet technology company Fi launched a dog tracker July 8 that uses T-Mobile’s Starlink-enabled T-Satellite service to remain connected across the United States, even outside the telco’s terrestrial network.
The company said Fi Ultra marks the first consumer product outside smartphones to ship with Starlink Direct-to-Cell as a core feature. T-Mobile has offered the satellite-enabled service commercially since 2025 after becoming an anchor telco partner for SpaceX’s low Earth orbit network.
The device is compatible with standard dog harnesses and collars, including those designed for older Fi trackers that can only broadcast GPS data when they can reach a cellular tower.
“For years, there’s been a hole in the market for a tracker for off-grid adventures,” Fi cofounder and CEO Jonathan Bensamoun said via email.
