Service plans explained

Whistle uses America's most reliable cellular network to pinpoint your pet's location at a moment's notice. Should your dog ever become lost, our service fee ensures you have the ability to locate them using GPS. Each device (and each additional pet) requires its own service plan.

Pre-paid service plans must be activated within 12 months of purchase. You will choose a service plan upon activation. It will only begin upon completion of your pre-paid service plan.
