About Fi

Established in 2017, Fi creates GPS-enabled smart dog collars to track where your pet is and what they’re doing. With LTE-M cellular networks and a dedicated mobile app, it offers live tracking, escape alerts, and daily activity tracking. The collar is rated IP68 waterproof and has a battery life of up to 3 months, depending on usage and settings. Fi has subscription plans to suit your tracking needs. Coverage is available across the contiguous U.S. and selected areas in Alaska and Hawaii to ensure you stay connected to your dog wherever there is coverage.

How Do I Apply a Fi Promo Code During Checkout to Save on a Dog Collar?

  1. Choose your Fi Collar: Visit the Fi Series 3 page and click the yellow 'Buy Now' button. Enter your dog's size and color. Click 'Next' to proceed.
  2. Select your subscription: Chose from 1 Year, 2 Year or 3 Year subscription plans. The 2 Year and 3 Year plans provide the best value for money. Click 'Next' to continue.
  3. Fill out shipping and billing details: Input your shipping address and payment information on the checkout page. All fields are laid out on one page layout.
  4. Fi promo code: On the checkout page, you will find the 'Gift card or discount code' box in the right-hand order summary section, just underneath the item total. Paste in your Fi coupon code from DontPayFull and click the 'Apply' button. The savings will appear in the order summary.
  5. Make your order: Click the 'Pay Now' button to finalize your purchase. Fi offers a 30-day trial and free U.S. shipping.

What should I do if my Fi coupon does not work?

  • Check plan compatibility: This promo code may only work with certain GPS tracker plans, including Pro and Lite subscription. If you're on a monthly trial or discounted base plan, the code will not work. Double check the terms of the plan before you try again.
  • Check device eligibility: Some codes only apply to new collar orders or specific generations of the tracker. If you manage to get a discount on an accessory or new collar, the code will be rejected.
  • Check for expired or single use codes: Most of their deals are time sensitive or single use per customer. If you've used a 20% off code before - even on a canceled order - the code can't be used again.
  • Use email or bundle offers: The best deals often come from email signups or holiday bundles that don't need a code. If your code is faulty, check the website for the total savings available on current automatic offers.

Fi Coupon & Discount Code FAQ: Smart Ways to Save on Dog Collars
