Most travellers use between 500 MB and 1.5 GB a day. Where you land in that range depends almost entirely on video.

What things use

Pick a plan

  • Light (maps, messaging, a bit of browsing, photos over Wi-Fi at night): about 500 MB a day.
  • Typical (all of the above plus social media and the odd video): about 1 GB a day.
  • Heavy (streaming, video calls home, hotspotting a laptop): 2 GB a day or more.
Multiply by your days and add a buffer. If you’re between two sizes, the bigger plan is usually cheaper than a second plan later, and if the plan is reloadable you can top up mid-trip anyway. Rather not count at all? Where a destination offers an Unlimited plan, you pay by the day instead of the gigabyte, with a full-speed allowance every day and no total to run out of. See How Unlimited plans work.

Ways to use less

  • Download maps, playlists and shows over hotel Wi-Fi before you head out.
  • Turn off automatic photo backup and app updates on mobile data.
  • On iPhone, Low Data Mode on the Roamly line; on Android, Data Saver.
  • Keep an eye on your plan page. The app shows data left and a day-by-day chart; the website adds your average per day and a forecast. See Check your data usage.
