Trax is supported in over 100 different countries.
In order to be able to monitor your Trax you need to have access to the Trax Play app, which means you will need internet connection for the app to send, receive and update information.
Currently, most mobile network operators in Europe offer free data-roaming within the EU.
However, make sure your check with your mobile network provider before your travel abroad to ensure you don't pay too much whilst travelling!
You can also use wifi to check the Trax app or login to your app account on a laptop or computer using the trax web app
