How much data does a trip need
In short: There is no single number that fits everyone — it depends on how many days you are away and what you do with your phone. If you run out, you can add a plan in your account area without buying everything again.
What actually uses data
Navigation, social media and ordinary browsing are the daily use for most travellers.
Video, and uploading photos at full quality, is what pushes consumption up more than anything else — especially on trips where you take a lot of pictures.
Long video calls home fall into the same category.
By length of trip
For a short weekend a small plan is usually enough — much of the time there is hotel Wi-Fi anyway.
For two weeks or more, assume continuous daily use including navigation, and choose accordingly.
For a long trip or remote work the question changes: there, data is a working tool rather than a convenience.
If you run out mid-trip
You can add a plan from your account area, without installing a new eSIM and without starting over.
The same place shows how much is left — which lets you decide before you run out rather than after.
Why not buy extra just in case
Too large a plan is money left unused; too small a one takes a minute to top up.
So the sensible approach is usually to start with a reasonable estimate and add as needed.
Frequently asked
What happens if I run out of data?

Where do I see how much data is left?
In your account area on the site, together with the option to add a plan.
