The Whistle 3 only works in the United States
The Whistle 3 Pet Tracker requires AT&T cellular coverage and is currently only functional within the United States, but we hope to expand internationally in the future.
If you purchased a Whistle 3 inside the United States and have taken it outside of the U.S., please be aware that we are unable to support your warranty. We will only support the Whistle 3 warranty if a user is operating one of our Whistle GPS enabled devices inside of the U.S.
Thank you for your interest in Whistle. We really appreciate our international supporters!
