With an active subscription, the Fi collar uses AT&T's LTE-M cellular network and acts as its own cellular device.
Prior to purchase, we recommend first checking to ensure there is LTE-M coverage around your home or in any other area where your dog may spend time. Please note:
- Your smartphone can be on any cellular network - it does not need to be on AT&T for the Fi Collar to function.
- Without a subscription, AT&T LTE-M network connectivity and 'Lost Dog Mode' are not available. If you did not select a plan during your initial purchase, you can always add a Fi Subscription at a later date. See: How Do I Add a Fi GPS/LTE Subscription?
Once you've received your Fi Collar, we recommend testing GPS and LTE capabilities by Testing Lost Dog Mode.
