3G Trackers

See how we compare to other smart collars.

The first smart collar on the LTE-M low power cellular network.

This network was specifically designed for devices like ours and offers us two major benefits:

Extended Cellular Coverage

Up To 30%
More Coverage

The LTE-M network has 20-30% more cellular coverage across the US than the regular 3G/LTE networks.

This means that we can track your dog in areas that 3G trackers cannot. So, if a previous 3G pet tracker has not worked in your area before - there’s a good chance Fi will.

Low Energy

BLE is used by all modern phones to communicate with other devices (Airpods, Fitbits, etc.).

The Fi collar leverages all BLE enabled devices in its proximity to determine its location very accurately and relay all tracking information to your Fi app.
