Tracking devices will not work outside of Australia, but you can access your Track and Monitor app and/or web portal outside of Australia when connected to the Internet (data charges may apply).
Telstra Track and Monitor is designed for use in Australia. Track and Monitor device location information is approximate only and may be unavailable if a device is no longer detected or in range of the Telstra Mobile Network, the Telstra Bluetooth Community and LTE-M technologies (as applicable).
