When you start using the TomTom GO Mobile app, you are given a set amount of free kilometres or miles so you can begin navigating immediately.
Depending on your country of download, you will receive either 75 kilometres or 50 miles for free. These free miles are reset at the start of each month.
This means that you start every month with 75 kilometres or 50 miles.
You will receive your free kilometres or miles each month when your device is connected to the internet.
