eSIM for Europe: does it cover the UK, Switzerland and Turkey?

Paris, then London, a train to Zurich and a few days in Istanbul. On a map it all looks like “Europe”. For mobile data, it is not one place. A plan sold as a “Europe eSIM” may cover some of those countries and not others, and the EU’s free-roaming rules may not help you at all.

This guide explains what an eSIM for Europe and the UK usually covers, what “Europe” means on a plan, why the UK, Switzerland, Türkiye (Turkey), the Western Balkans and Europe’s microstates are the usual gaps, and how to check a plan before you pay. We checked each rule on official EU, UK, Swiss and Turkish government pages and on Apple and Google support pages on 6 October 2026. Voyfaro is not affiliated with any government, regulator or mobile operator.

Quick answer

• “Europe” on an eSIM is a seller’s label, not a legal area. Each plan has its own country list, and two plans with the same name can cover different countries.
• The usual gaps are non-EU countries: the United Kingdom, Switzerland, Türkiye, the Western Balkans (such as Serbia, Albania and Bosnia and Herzegovina) and microstates such as Andorra, Monaco, San Marino and Vatican City. Some plans include them, others do not.
• EU “Roam like at home” depends on your home SIM, not your destination. It covers people with a mobile subscription from an operator in the EU, Iceland, Liechtenstein, Norway, Ukraine or Moldova, roaming within that area. If your SIM is from the US, the UK, India, the Gulf or anywhere else outside that area, the EU rules do not set your price.
• The UK is outside the EU roaming area. The European Commission says Roam like at home does not apply to travel to the UK, although some operators choose to include it. The UK government says UK customers can no longer count on surcharge-free roaming in the EU.
• Before you buy: read the plan’s full country list, and check whether it is data only, whether hotspot is allowed and whether there is a fair use limit. Make sure your phone supports eSIM and is unlocked.

Who this applies to

• Visitors from outside Europe, for example from the US, Canada, Brazil, India, the Gulf, Nigeria or Australia, planning a trip across several European countries.
• UK residents travelling to the EU, or adding Switzerland or Türkiye to a trip.
• EU residents visiting the UK, Switzerland, Türkiye or the Western Balkans, where EU roaming rules do not apply.
• Anyone mixing Schengen and non-Schengen stops, such as London and Paris, or Rome and Istanbul.

Staying in one country for weeks? A local SIM may suit you better. Our guide to eSIM vs roaming vs local SIM compares the options.

What “Europe” eSIM plans usually cover

There is no official definition of a “Europe eSIM”. Each provider builds its own plans, based on the networks it has agreements with. When you look at a plan, sort the countries on your route into three groups:

This is a pattern, not a rule. A plan can leave out an EU country, and some include countries well outside Europe. Only the coverage list for the exact plan you buy counts.

Schengen, the EU and the roaming area are different maps

• Switzerland is in the Schengen area but not in the EU or the EU roaming area.
• Ireland and Cyprus are in the EU and the EU roaming area, but not full Schengen members: Ireland has an opt-out, and Cyprus still has internal border controls while it joins. Our EES and ETIAS guide lists the 29 countries using the EES.
• Ukraine and Moldova are not in the EU, but have been part of the Roam like at home area since 1 January 2026.
• The UK is in none of the three.

So “my visa covers it” or “it’s in Europe” tells you nothing about whether your data plan works there.

How EU “Roam like at home” really works

Roam like at home (RLAH) has applied since 15 June 2017. People with a mobile plan from an operator in the EU, Iceland, Liechtenstein or Norway can call, text and use data in the other countries in that area at their home prices. Since 1 January 2026 it also covers Ukraine and Moldova, in both directions. The European Commission says the rules have been extended until 2032.

Three points matter for travellers:

1. It depends on your subscription. The EU’s Your Europe page defines roaming as using your phone while occasionally travelling outside the country where you have a mobile subscription: where you live, work, study or have stable links. A tourist with a SIM from New York, Mumbai, Dubai or London is not an EU roaming customer. Their home operator sets the price.
2. It only covers certain countries. The Commission says countries outside the EU/EEA are not covered, although many operators choose to extend their offers to them. It names the UK as outside the scheme. Switzerland, Türkiye, the Western Balkans, Andorra, Monaco, San Marino and Vatican City are not on the official list of countries where it applies.
3. It is for periodic travel. Operators can check your use over 4 months. If you spend more time and use more data abroad than at home, they may contact you and then add capped surcharges. On some plans with unlimited or very cheap data, a roaming data limit can apply, and your operator must tell you about it in advance.

It also covers only land-based mobile networks. On a ferry on open water or on a plane, your phone may connect to a satellite network. These services are outside the EU price caps and are usually expensive. For customers of EU/EEA operators, the EU says service should stop once you reach €50 of extra charges (or another set limit) unless you choose to continue.

Western Balkans: the Commission has proposed opening negotiations to bring Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia into the area. The Commission says there is no set deadline. For now, a voluntary agreement between EU and Western Balkan operators caps retail data roaming prices. That deal is between operators. It does not mean a travel eSIM includes these countries.

Country by country: the usual gaps

United Kingdom

• EU SIM going to the UK: the Commission says Roam like at home does not apply. Some operators include the UK anyway, but they do not have to. Check with your operator.
• UK SIM going to the EU: the UK government says surcharge-free roaming in the EU and EEA can no longer be taken for granted and advises checking your operator’s roaming policy before you travel. The old legal £45 monthly cap on data spending abroad no longer applies: the UK law behind it was revoked in 2023. Ofcom, the UK regulator, says providers must publish their roaming charges and must send you an automatic message when you enter another country, explaining any roaming charges or usage limits (unless you have opted out). Ofcom also says you can set a monthly spend limit on your bill: your provider must warn you when you are likely to reach it, and can only charge more if you agree.
• Visitors with a travel eSIM: check that the UK is named on the plan. If you are flying in, also check whether you need a UK ETA. See our UK ETA guide.

Switzerland

Switzerland is not in the EU or the EEA, so EU roaming rules do not cover it. Switzerland’s Federal Office of Communications (OFCOM) says Swiss providers must agree roaming deals with foreign operators, and Swiss law sets separate roaming rules for Swiss customers. For a visitor, the practical point is simple: a plan that lists “EU countries” may not include Switzerland. Look for it by name.

Türkiye (Turkey)

Türkiye is outside the EU roaming area, and regional plans treat it in different ways: some include it, some leave it out, and some sell it separately. If Istanbul or the coast is part of your trip, check that Türkiye is on the coverage list, or plan a separate eSIM for that leg.

Staying longer? Türkiye’s telecoms regulator, BTK, says phones brought from abroad can be used for 120 days without registration, after which unregistered devices are cut off. Its consumer page does not say how this applies to a phone used only on a foreign SIM or travel eSIM. If you will be in Türkiye for close to four months, check with BTK first.

Microstates

Andorra, Monaco, San Marino and Vatican City are not EU or EEA countries, so they are not on the official Roam like at home list. Some travel plans name them, others do not. If a day trip to Monaco or a ski week in Andorra matters to you, check the plan’s list rather than assuming.

How to check a plan before you buy

1. List every country on your route, including day trips, ferry stops and layovers where you will need data.
2. Open the full coverage list for the exact plan, not the headline, and find each country by name.
3. Check if it is data only. Many travel eSIMs give data without a phone number. Apple says many local network providers’ plans come with a local number, while worldwide service providers offer prepaid data plans. If you need a local number for calls, choose accordingly.
4. Check hotspot (tethering). Apple says Personal Hotspot needs a provider that supports it, and extra fees may apply. Some travel plans block or limit it.
5. Check fair use and speed limits. Some plans sold as “unlimited” slow your speed after a set amount of data.
6. Check when validity starts. Depending on the provider, a plan may start when you install it or when you first connect abroad. Check the provider’s terms.
7. Check refund and support terms, in case your phone turns out not to be compatible.

Is your phone ready for an eSIM?

You need a phone that supports eSIM and is not locked to one network.

iPhone. Apple says you need an iPhone XS, iPhone XS Max, iPhone XR or later, a provider that supports eSIM, and usually a Wi-Fi connection to set it up. To check if it is unlocked, go to Settings > General > About: “No SIM Restrictions” appears next to Network Provider Lock if it is. iPhone 13 and later can use two eSIMs at once, so you can keep your home line for calls and texts and use the travel eSIM for data. Apple warns that if you keep both lines on, you might still incur roaming fees from your home line, so check its roaming settings before you go.

Google Pixel and Android. Google says a SIM-unlocked Pixel works with any mobile service provider, and all phones sold in the Google Store come unlocked. On a Pixel, add an eSIM under Settings > Network and internet > SIMs > Add SIM > Set up an eSIM. Other Android brands use different menus, and not every model supports eSIM, so check your phone maker’s support page.

If your phone is locked, ask the operator that sold it whether it can be unlocked.

Common mistakes and scams to avoid

• Trusting the plan name. “Europe”, “Europe plus” and “Global” mean whatever the seller decides. Read the country list.
• Assuming EU free roaming covers you. It applies to subscriptions from operators in the EU/EEA, Ukraine and Moldova. A visitor’s home SIM is priced by their home operator.
• Forgetting the UK, Switzerland or Türkiye leg. These are often left out of regional plans.
• Leaving data roaming on for your home line. Turn it off on the line you are not using for data.
• Using data on a ferry or flight where the phone joins a satellite network, outside EU price caps.
• Deleting the eSIM by mistake. Some travel eSIMs cannot be reinstalled. Check your provider’s terms and keep it until your trip is over.
• Buying through links in unsolicited messages or from unknown social media sellers. Buy from a provider’s own website or app, and never share your QR code or activation details.

FAQ

Does a Europe eSIM work in the UK?

Only if the UK is on that plan’s coverage list. Some regional plans include it and some do not. The UK is outside the EU’s Roam like at home area, so do not assume it is included.

Is Switzerland included in Europe eSIM plans?

Sometimes. Switzerland is in the Schengen area but not in the EU or the EEA, so EU roaming rules do not cover it. Look for Switzerland by name on the plan’s country list.

Does a Europe eSIM cover Turkey?

It depends on the plan. Türkiye is outside the EU roaming area, and some regional plans leave it out or sell it separately. Confirm it is listed before you buy.

I have a US, Indian or Gulf SIM. Does EU “Roam like at home” apply to me?

No. It applies to customers of mobile operators in the EU, Iceland, Liechtenstein, Norway, Ukraine and Moldova, roaming within that area. Your home operator sets your roaming price, so a travel eSIM or local SIM is worth comparing.

Do Europe eSIMs come with a phone number?

Many travel eSIMs are data only. You can still use messaging and internet calling apps, and on a dual-SIM phone you can keep your home number on for texts. If you need a local number, choose a plan that includes one, or a local SIM.

Does Voyfaro sell eSIMs?

No. We help you compare eSIM plans from partners. You buy directly from the partner, which sets the coverage, price and terms.
