GPS is a positioning technology that can determine the position of your dog relative to the boundaries you have set. Cellular is a communication technology that enables your SpotOn collar to communicate with your smartphone at long distances. Bluetooth is also a communication technology that enables your SpotOn system to communicate with your smartphone but only at short distances.

To keep your dog safely contained, SpotOn uses GPS data from three satellite systems to create, control, and maintain your dog’s fences. GPS works without cellular. This means you can use SpotOn’s fences for containment without a cellular subscription.

Please note SpotOn uses T-Mobile 3G cellular data. T-Mobile's 3G network will end its service in July 2022. At that time you WILL be able to create and save GPS fences but you WILL NOT be able to track your dog's location, get escape and low battery notifications, or view or name new fences on in the app.
