Europe eSIM guide: one plan for 34 countries

A Europe eSIM gives you one data plan for 34 countries: all 27 EU countries plus the UK, Switzerland, Norway, Iceland, Liechtenstein, Turkey and Ukraine. It connects to a local network in each country and switches by itself when you cross a border. Install it at home from the QR code and keep your own SIM for calls and bank SMS.

What to expect on the road

Where	What to expect
Vienna and Prague	Good 4G and 5G in the centre. Packed Christmas market squares can slow data in the evening.
Paris, Rome, Barcelona	Fast coverage in city centres, airports and main stations. Metro coverage varies by line.
On the train	Data works on most routes. Expect drops in tunnels, mountain passes and rural stretches.
At the border	The phone moves to a local network in the new country, usually within minutes. No action needed.
London and Zurich	The UK and Switzerland are on the coverage list, so a London or Swiss leg needs no second eSIM.

One eSIM for many countries

A regional eSIM is a single data line that roams onto a local network in each covered country. When you cross a border by train, bus or plane, your phone drops the old network and registers on a new one.

This happens automatically, usually within a few minutes. Keep data roaming switched on for the eSIM line, or the phone will not connect abroad.

Near a border the phone may stay on the neighbouring country’s network for a while. If that country is on the list, data keeps working.

Which countries are included

All 27 EU countries, from Portugal to Finland and from Ireland to Cyprus.
Outside the EU: the United Kingdom, Switzerland, Norway, Iceland, Liechtenstein, Turkey and Ukraine.
Balkans: Croatia, Slovenia, Greece, Bulgaria and Romania are on the list. Serbia, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia and Kosovo are not.
Monaco and Andorra are not on the list. Check the full list on the plan page before you buy.
For Serbia or North Macedonia, the Europe 40 plan covers them.

Do EU residents need a Europe eSIM?

Usually not. Under the EU’s roam-like-at-home rules, an EU SIM works across the EU, Iceland, Liechtenstein and Norway at domestic rates until 2032.

Operators can apply fair-use limits when a SIM is used mainly abroad over a long period. That can matter for an Erasmus semester.

The UK and Switzerland are outside these rules, so many EU plans charge extra there.

Who it is for

Visitors from outside the EU, for example from Turkey, the US, the Gulf or Asia, whose carriers charge for roaming in Europe.
Turkish travellers on a Schengen trip: your Turkish line stays in the phone for SMS, while the eSIM handles data.
Non-EU students on Erasmus, during the first weeks before they get a local contract.
EU residents whose home plan has little data, or who are heading to the UK or Switzerland.

How much data you need

Maps, train apps and messaging: about 1 GB for a long weekend.
Daily photos, stories and some video calls: 3–5 GB for one to two weeks.
A month of study or remote work, streaming or a laptop hotspot: 20 GB or an unlimited plan.

Christmas markets 2026

Vienna’s Christkindlmarkt at Rathausplatz runs from 13 November to 26 December 2026, daily 10:00–22:00, closing at 18:30 on 24 December.

Prague’s Old Town Square market runs from 28 November 2026 to 6 January 2027. A Vienna–Prague weekend is one plan, since Austria and Czechia are both covered.

Evening crowds slow mobile data in the squares. Save tickets and meeting points on your phone before you go.

Setup

Check that your phone supports eSIM and is carrier-unlocked.
At home, on Wi-Fi, scan the QR code to add the eSIM. The plan starts on its first connection in a covered country.
After landing, choose the eSIM for mobile data and turn on data roaming for that line only.

Frequently asked questions

Does one eSIM work in all European countries?

One eSIM covers 34 European countries, including all 27 EU members, the UK and Switzerland. A few countries are not on the list, such as Serbia, Albania, Monaco and Andorra. Check the full list on the plan page before you buy.

Does the Europe eSIM work in the UK and Switzerland?

Yes, both the United Kingdom and Switzerland are on the coverage list. A trip that combines London, Paris and Zurich needs only this one plan.

Does the Europe eSIM work in Turkey and the Balkans?

Turkey is included, and so are Croatia, Slovenia, Greece, Bulgaria and Romania. Serbia, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia and Kosovo are not on the list.

Do I need a Europe eSIM if I have an EU SIM card?

Usually not, because EU roam-like-at-home rules cover the EU, Iceland, Liechtenstein and Norway until 2032. An eSIM helps if your plan has little data or if you are going to the UK or Switzerland.

What happens when I cross a border?

The eSIM switches to a local network in the new country automatically, usually within a few minutes. Keep data roaming on for the eSIM line so it can connect.

How much data do I need for two weeks in Europe?

About 3–5 GB covers maps, messaging, photos and some video calls for two weeks. Pick 20 GB or an unlimited plan if you stream or use a laptop hotspot.

When does the Europe eSIM plan start?

The plan starts on its first connection in a covered country. You can install it at home days before you fly without losing any days.
