How Much Data for 2 Weeks in Europe?

2026-10-23 · 3 min read

For 14 days in Europe, most travellers need about 3.3 GB if they mainly use maps and messages, about 8.1 GB if they post and share photos every day, and about 21 GB if they stream or run a hotspot. Here is where those numbers come from, and how to adjust them for your own trip.

Our general guide on how much data you need explains the rates and covers any trip length. This post does the maths for one common case: two weeks, one continent, several countries.

Three ways of using your phone

We size plans with three daily rates, then add 15% headroom for the days that run heavier than planned.

Most trips are mixed

Few people use data the same way every day. Do the maths by blocks of days.

Example: city break plus road trip. Ten days of sightseeing at the socials rate, then four days driving with a hotspot for a passenger's tablet:

• 10 × 0.5 GB = 5 GB
• 4 × 1.3 GB = 5.2 GB
• Total 10.2 GB, plus 15% = about 11.7 GB

Example: mostly offline, a few work days. Eleven days of maps and messaging, three days of hotspot for a laptop:

• 11 × 0.2 GB = 2.2 GB
• 3 × 1.3 GB = 3.9 GB
• Total 6.1 GB, plus 15% = about 7 GB

For hotspot days, most plans allow sharing, but it depends on the local network. Check the plan details before you rely on it. A laptop on a hotspot behaves differently from a phone; see using an eSIM as a laptop hotspot.

What shifts the number in Europe

• Accommodation Wi-Fi. If your hotels and apartments have good Wi-Fi, your mobile data covers only the hours you are out. The daily rates already assume that.
• Train days. Long rail journeys invite streaming. Download films and playlists on Wi-Fi the night before.
• Photo backup. Set cloud backup to Wi-Fi only, or a single upload of holiday videos can use days of data.
• Offline maps. Downloading each city's map in advance keeps navigation cheap even at the lightest rate.

Fixed data or unlimited?

For the first two rows, a fixed-data plan of the right size is usually enough, and you can top up if you run short. At the streaming rate, compare unlimited too: it has a daily high-speed cap shown on the plan, so check your heaviest day against it. Fixed data or unlimited walks through that comparison.

Make sure the plan lasts 14 days and covers your route

Choose a plan whose validity covers the whole trip. Validity starts when the eSIM first connects in Europe, not when you buy or install it, so you can install at home days before.

Then check the route. The Europe eSIM covers the EU and the UK and also, at the time of writing, Switzerland, Norway, Iceland, Türkiye, the western Balkans and more. The EU & UK eSIM covers the 27 EU states plus the UK. If your two weeks include Switzerland or a Balkan stop, that matters: Europe or EU & UK shows how to check a route. The Europe guide lists coverage and networks, and our post on multi-country trips covers border crossings. Visiting from outside the EU? Roaming in Europe without an EU SIM explains why your home plan may not cover this.

Check halfway

On day seven, compare what you have used with your plan. At the socials rate you should be near 3.5 GB. If you are well above, top up from your account page or move heavy use to Wi-Fi. Here is how to check your usage.
