When you start using the TomTom GO Mobile app, you are given a set amount of kilometres or miles included, so you can begin navigating immediately.
Depending on your country of download, you will receive either 75 kilometres or 50 miles. The included 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 included kilometres or miles each month when your device is connected to the internet.
