Frequently Asked Questions

What is Whistle GO & Whistle GO Explore?

Whistle GO and Whistle GO Explore are the most comprehensive pet trackers on the market—the only pet wearables, in fact, that put GPS tracking plus fitness and health monitoring all into one simple device. Both Whistle GO and Whistle GO Explore let you pinpoint your pet’s precise location with real-time tracking. Both monitor behaviors that may be early-warning signs of potential health issues. You’ll always know where your pet went and with whom. And with both, you can set and track fitness goals based on age, weight, and breed, plus review weekly reports that summarize your pet’s activities and insights.

What makes Whistle GO Explore different is a longer battery life (up to 20 days on a single charge) and a built-in light that you can use as night light during evening walks—or as a beacon to spot your dog in the dark.

Just attach the device to your pet’s collar, and customize the Whistle app to send alerts and notifications to the key people in your pack.

How does the technology work?
You will first set up a Safe Place (i.e. home, vacation home, dog sitter, etc.) for your pet using Wi-Fi. Good news is, you can have multiple Safe Places depending on where your pet spends most of their time. When your pet’s Whistle is connected to Wi-Fi, it is in power save mode (using very little battery).

Whistle will then notify you each time your pet leaves and returns to their Safe Place. Once your pet is beyond Wi-Fi range, the device uses cellular and GPS technology to allow you to enable tracking anywhere in the U.S. Whistle is the most advanced pet tracker since it uses GPS, Wi-Fi and cellular technology (on America's largest network) to locate your pet 24/7.

Why do I need a subscription for my Whistle tracker?

Whistle trackers are both a device and service. Subscription plans cover health and fitness monitoring, including proactive notifications, alerts, personalized health reports and more. The Whistle GO + Whistle GO Explore subscription plans also cover cellular data connection to provide GPS location tracking. No new phone contract required. During the in-app activation process, you will be prompted to select a Whistle subscription plan.

Do I need to have a mobile phone with an AT&T® contract to use a Whistle device?

No. Whistle trackers use AT&T®, America’s Largest Cellular Network, for on-demand location tracking, but this is separate and distinct from the service plan you have for your mobile phone. As long as you have cellular data and reception on your iOS or Android phone, you'll be able to use the Whistle app to communicate with your Whistle tracker.

Will Whistle devices work in areas where there is no cellular service?

No. To locate your pet and communicate with your smartphone, Whistle trackers require cellular service. While your mobile phone only requires Wi-Fi connection to request real-time location tracking through the Whistle app, the tracking device itself requires cellular service to communicate GPS updates back to your phone. Need help determining AT&T coverage in your area? Give us a call.

How long does the battery last on Whistle trackers?

Whistle GO Explore—Up to 20 days on a single charge. Actual time varies based on Wi-Fi strength of and cellular coverage.

Whistle GO—Up to 10 days on a single charge. Actual time varies based on strength of Wi-Fi and cellular coverage.

Whistle FIT—Up to 15 days on a single charge. Actual time varies based on strength of Wi-Fi and cellular coverage.

You’ll get a proactive alert when it’s time to recharge the battery, and the device only takes 2 hours to fully charge. The more time your pet spends out of your established Wi-Fi range, the faster the battery drains. To ensure adequate charge for your pet’s everyday and unexpected adventures alike, we recommend charging every 2-3 days. Learn more about battery life.
