How much mobile data do you need when travelling?

How much data do you need on a trip? It is the question every traveller asks when choosing an eSIM. Too little and you run out halfway, too much and you pay for nothing. This guide gives you a clear guideline per trip type and activity, with tips to make your bundle last longer.

Guideline per trip type

Type of travellerUsageRecommended data
Light (weekend)Maps, WhatsApp, occasional social media1 to 3 GB
Average (week)Social media, sharing photos, navigation5 GB
Intensive (1 to 2 weeks)Lots of navigation, videos, stories10 GB
Long trip or sharingTethering, working, family20 GB or more
If you are hesitating between two sizes, choose the larger one. A few euros extra is always cheaper than running out of data halfway through your trip and having to buy more in a hurry.

What uses a lot, what uses little?

ActivityUsage per hour (guideline)
Messages and mapsVery little
Scrolling social mediaAbout 0.5 to 1 GB
Streaming musicAbout 0.5 GB
Streaming video (HD)1 to 3 GB
Video callingAbout 1 GB

Videos and uploads weigh the heaviest. Maps and messages cost almost nothing.

Tips to save your bundle

  • Download offline maps and your travel route before you leave.
  • Turn off autoplay video in social apps.
  • Stream downloaded music and series instead of live.
  • Set cloud backups and updates to Wi-Fi only.
  • Do large downloads over the Wi-Fi at your accommodation.

If you pay attention to this, you often get surprisingly far on 5 or 10 GB. If you do run short, with many eSIMs you can top up.
