Here's Why We Have A Subscription on the Whistle 3
Each Whistle has a cellular chip embedded in the device - It's how the device connects to the network so we can track your furry friend wherever they are. In order to make things simpler on your end, Whistle manages everything for you so you don't have to worry. Think of it like us paying your pet's cell-phone bill :)
Keep in mind that each device will require a separate subscription.
