How Much Data Do You Need for Travel? A Calculator Guide

For a one-week trip, light users need about 1 to 3 GB, moderate users 5 to 10 GB, and heavy users who stream or hotspot should choose a large or unlimited plan. Free Wi-Fi reduces how much mobile data you actually use.

A simple guide

  • Maps and messaging: ~1-3 GB/week.
  • Social media and photos: ~5-10 GB/week.
  • Streaming or hotspot: large or unlimited.

Right-size it

Start moderate and top up a reloadable plan if you run low. See choosing a plan size.
