Meet the Fi Ultra, our most advanced GPS tracker built for pets who love to explore remote areas.
With extended LTE coverage on the T-Mobile network and satellite coverage powered by T-Satellite with Starlink, the Fi Ultra keeps you connected to your dog even in areas without standard cellular coverage. The universal integrated clip works on harnesses, working dog vests, and thick leather collars. Perfect for outdoor adventures and rural properties.
Please note: The Fi Ultra is only compatible with dog profiles. It cannot be purchased for cats or added to existing cat profiles.
Important: The Fi Ultra is currently designed for use within the United States only and will not function in other countries, even with satellite connectivity. Additionally, T-Satellite with Starlink coverage is not available in Alaska.

Pricing
Your Fi Ultra and your Fi Membership are priced separately. You pay for the tracker at checkout, and your membership is charged when you activate. How much you pay depends on whether you are buying the Fi Ultra on its own or adding it to a Fi tracker you already own.
Fi Ultra Only
If you are purchasing a Fi Ultra and do not own a Fi Mini, Series 3+, or Series 3, you will pay two separate charges:
- A one-time hardware fee for the tracker, billed at checkout
- Your prepaid membership term, billed when you activate your tracker
Promotional pricing may lower the tracker amount. The price you pay is shown at checkout before you place your order.
For membership term options and pricing, visit our Membership article.
We recommend activating your tracker as soon as it arrives. If your tracker is not activated within 7 days of shipping, your membership will start automatically.
Standalone Ultra members will have the opportunity to purchase a Fi Mini or Series 3+ at a later date directly in the Fi app. The new tracker will be added to your existing Fi Ultra membership, so no additional membership is needed.
Fi Ultra with Fi Mini, Series 3+, or Series 3
You can purchase the Fi Ultra as a secondary tracker to your pet's existing tracker by paying a one-time hardware fee for the tracker, billed at checkout.
Your existing membership is preserved, and no new membership is needed. Your renewal date and renewal price do not change.
To purchase your Fi Ultra, log in to the Fi app or website and place your order from your account.
