Frequently asked question

Do I need to have an AT&T Plan to use my Whistle?

No, your Whistle tracker is like a miniature cell phone for your dog! As such, it requires its own cellular plan, but is separate from the plan you have for your own phone. Whistle leverages AT&T’s 4G network to provide you the greatest coverage and fastest response, but you don’t need to be an AT&T customer to use Whistle. Your 360 subscription plan takes care of the cellular connection, so you can keep on adventuring with no interruptions

How do I cancel my Whistle subscription?

What is your return policy?

Can I use the Whistle GO on more than one pet?
