Fi Ultra becomes first Starlink-enabled pet tracker for dead zones

Fi Ultra went on sale on July 8, 2026 as the first pet tracker that can hand off from cellular service to Starlink when a dog runs into a dead zone. The collar combines GPS, LTE and T-Mobile’s T-Satellite direct-to-cell network, so owners can keep tracking in most outdoor areas where they can see the sky.

The earlier Series 3 collars relied on GPS plus LTE-M and LTE networks, which can fail in remote areas. The Ultra is aimed at dogs that roam on hikes, farms and back roads, where a lost pet can move out of range fast.

Fi priced the new collar at $199 for new members, plus a $20 activation fee and a $189 annual subscription. Existing Fi members can buy it for $299 and add it to a current plan. The device works with most standard collars and harnesses, and it has up to three months of battery life, wireless charging, escape alerts, Lost Dog Mode and a built-in light, with Safe Zone boundary sound and vibration triggers coming soon.

Fi already offers the Fi Mini for smaller pets, while the Series 3+ remains its main collar line, and the broader ecosystem includes AI-powered health and behavior monitoring, Apple Watch integration and Bluetooth base stations that extend coverage at home or at a second location.

Whistle, once one of the best-known GPS pet tracker brands, shut down in 2025 after being acquired by Tractive.

T-Satellite with Starlink activates automatically and can be added for $10 a month, or is included with some plans. Nearly 2 million people tried the service during T-Mobile’s beta, while more than 650 Starlink satellites now support SpaceX’s Direct to Cell network.
