How many GB do I need for a trip to Europe? The quick math based on how you travel

For most travelers, 5 to 10 GB is more than enough for a one- or two-week trip to Europe. If you only use maps, messaging and social media in moderation, 3-5 GB will do. If you’re on a lot of video calls, uploading content or streaming video, go for 10-20 GB or an unlimited plan.

The truth? Almost nobody uses as much as they think. The trick isn’t guessing, it’s doing a quick tally of how you actually use your phone. Here’s the easy version: it’s the same one we panda-team folks run so we don’t overshoot or come up short halfway through a trip.

How much data does each thing I do on my phone use?

See the pattern? Maps and chat barely weigh a thing; what really eats your GB is video and long video calls. Keep that on your radar and half the math is already done.

Which plan suits me based on how I travel?

Find yourself in one of the three rows and multiply by the weeks you’ll be away. Simple. And if you’re right between two, bump up a notch: running out of data mid-stroll through Santorini is way more annoying than a few GB to spare. 🙂

Frequently asked questions

Is 5 GB enough for 10 days in Europe?

For moderate use (maps, chat, social and some photos), it usually is more than enough. If you stream video every day, aim for 10 GB or an unlimited plan and travel worry-free.

Is an unlimited plan worth it?

If you work on the road, make lots of video calls or stream video, unlimited gives you that peace of mind. For regular sightseeing, 5-10 GB is plenty.

What happens if I run out of data?

Nothing serious. With an eSIM you top up instantly from your phone, no buying a new SIM or hunting for a store.
