Use Wi-Fi for the big stuff

Download films and playlists at home or on hotel Wi-Fi. Streaming HD video is by far the biggest data user.

Drop the quality

Set Netflix, YouTube and Instagram to "data saver" on mobile. It can cut video use by more than half.

Offline maps

Download the map for where you're going. Navigation then uses almost no data.
