Frequently Asked Questions
What does the Fi membership include?
Fi membership powers the cellular GPS connection your collar uses, plus the full Fi app experience: live location, escape alerts, Lost Dog Mode, Search Party, activity and sleep tracking, and ongoing service and software updates.
How much does Fi membership cost?
Fi membership starts at $19/month. Longer prepaid terms (multi-month or annual) bring the effective monthly cost down. Current pricing and term options are on the membership page and at checkout.
Why does Fi require a membership?
The membership covers the cellular network connectivity (LTE-M) the collar uses to report your dog’s location, plus ongoing app development, server costs, and customer support. Without a membership, the cellular GPS does not function.
Can I pay monthly, or only annually?
Both. You can choose a month-to-month membership or a longer prepaid term that lowers the effective monthly cost. The exact term options are shown at checkout.
Is there a free trial of the membership?
Promotional free trials and discounts are offered from time to time. Any active offer will appear during checkout — check the membership page or your cart for current promotions.
How do I cancel my Fi membership?
You can manage or cancel your Fi membership from the Fi app under account settings or by contacting Fi support. Cancellation stops future billing; refund and proration terms depend on the plan you originally chose.
Are membership fees refundable?
Refund eligibility depends on the membership plan and how long it has been active. See Fi’s membership terms or contact support for the specifics that apply to your plan.
What happens to my collar if my membership lapses?
If your membership lapses, the cellular GPS connection stops, so the collar can no longer report live location to the app. Reactivating the membership restores tracking.
Do I need a separate membership for each dog?
Yes. Each Fi collar requires its own active membership, since each collar uses its own cellular connection. You can manage multiple memberships under one Fi account.
Is there a multi-pet discount?
Multi-pet pricing options can change over time and around promotions. Check the membership page or contact support for any current multi-pet offers.
Does the membership cover Fi Mini and Fi Series 3+ the same way?
Yes. Fi membership covers the cellular GPS and app features for both Fi Series 3+ collars and Fi Mini trackers. The plan options are the same — pricing varies by term length, not device.
Can I transfer my membership to a new collar?
Yes. If you upgrade or replace your Fi device, you can transfer your active membership to the new device through the Fi app or with help from Fi support.
Does the membership work outside the United States?
Fi memberships are designed for use in the United States and Canada. Coverage and feature availability outside those regions vary; check support before traveling internationally.
What is included in Lost Dog Mode and Search Party?
Lost Dog Mode increases the rate at which the collar reports location for live tracking. Search Party lets nearby Fi members anonymously help locate a missing dog. Both are included in the Fi membership.
How do I contact Fi support about my membership?
You can reach Fi support through the Fi app or the support link in the site footer. Support can help with billing questions, transfers, and cancellations.
