Overview
- Fi launched the Fi Ultra on Wednesday, July 8, 2026, and is selling the device in the United States for $199 plus a $20 activation fee with an annual membership starting at $189 or a $299 flat price for existing Fi members.
- The device uses T‑Mobile’s T‑Satellite service with Starlink alongside LTE and dual-band GPS, automatically switching between networks to maintain location updates where cell towers do not reach.
- User-facing features include geofencing alerts, a Lost Mode that can notify nearby Fi users, and a sound-and-vibration callback system to help guide dogs back to their owners.
- Fi reports about two days of battery life on a single USB‑C charge, a tradeoff from the company’s longer-lived models that reflects the energy cost of always-on GPS and satellite connectivity.
- The product builds on T‑Mobile’s 2025 rollout of Starlink Direct-to-Cell and could widen satellite-backed consumer wearables, but higher recurring fees and shorter battery life will shape adoption among rural and off-grid dog owners.
