Fi Ultra pet tracker uses T-Mobile's Starlink satellite service for coverage

Gus, the wirehaired pointing griffon, models the Fi Ultra while overlooking Charleston Harbor. Fi Ultra is the first Starlink-enabled pet tracker you can buy. It expands on GPS and LTE trackers, adding automatic failover to T-Mobile's T-Satellite-branded direct-to-cell service when venturing into cellular dead zones. That lets owners tap into SpaceX's constellation of low Earth orbit Starlink satellites to track their pets anywhere in the US. But it comes with a few tradeoffs based on our early testing, including relatively poor battery life for a pet tracker.
