Europe eSIM

Thirty-three countries on one eSIM, from Reykjavík to Nicosia, including the UK and Switzerland, where EU "roam like at home" deals stop. If your SIM is from an EU country you usually don't need us inside the EU; this page is for visitors from the UK, the US, Canada, Australia and beyond, and for EU residents heading to London or Zurich.

What a week of data costs in Europe

Prices for 7 days of data, checked on 2 November 2026. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. O2 and T-Mobile customers may need nothing extra for a short trip, though T-Mobile's 256 kbps after the high-speed allowance is slow for maps and photos.

If you live in the EU, your own SIM already roams like at home across the EU, Iceland, Liechtenstein and Norway, and in Ukraine and Moldova, as long as you spend more time at home than abroad. The UK and Switzerland aren't in that regime, so that's where EU residents get a surprise bill. The same rules apply to an EU tourist SIM such as Orange Holiday, but that SIM covers the UK and Switzerland only because Orange chooses to include them.

Landing at Heathrow, Paris CDG, Frankfurt, Schiphol, Rome or Madrid

Switch the kimsim line on as the plane taxis to the gate and turn on Data Roaming for that line only. Then walk through passport control, collect your bags and go through customs. With the eSIM already working, you can walk past the SIM counters; Orange Holiday SIMs, for example, are sold at the airport and in Relay shops.

Into the city:

• London Heathrow: Heathrow Express reaches Paddington in 15 minutes; the Elizabeth line reaches central London in under 40.
• Paris CDG: RER B to Gare du Nord takes about 25 minutes.
• Amsterdam Schiphol: trains to Amsterdam Centraal take about 17 minutes, from the station under the terminal.
• Frankfurt: S8 and S9 S-Bahn trains leave the regional station under Terminal 1 every 15 minutes in the daytime.
• Rome Fiumicino: the Leonardo Express runs non-stop to Roma Termini in 32 minutes.
• Madrid Barajas: Metro line 8 runs to Nuevos Ministerios, with a €3 airport supplement on the ticket.

Entry rules. Since 12 October 2025, the EU's Entry/Exit System records non-EU visitors' fingerprints and a photo at the Schengen border, and it has been fully in place since 10 April 2026. ETIAS, the €20 travel authorisation for visa-free visitors, is not in operation yet; the official site says the EU will announce the start date several months ahead. So don't pay any website that offers you an ETIAS today. The UK is separate: most visitors, including Europeans, Americans, Canadians and Australians, need a £20 Electronic Travel Authorisation before they fly.

Networks and coverage

In each country, this plan uses one to four local networks, such as Orange and Movistar in Spain, KPN in the Netherlands or Telia and Telenor in Norway. In France it uses SFR only. Your phone picks the strongest one and shows that operator's name, not kimsim. When you cross a border, it moves to the next country's network on its own.

Two names may surprise you. In the UK, Vodafone and Three merged into VodafoneThree on 31 May 2025, so expect either name. In Greece, "Wind" is the old name of the network now called Nova.

Coverage is generally strong in cities and along main roads and rail lines. Expect gaps in mountain valleys, in long tunnels, in Iceland's interior, on Norwegian fjords and on the smaller Greek islands. Near a border, your phone can latch onto the neighbour's network early. That's fine if the neighbour is on the list, but it means no data if it isn't: think Albania across the water from Corfu, or Monaco on the Riviera.

At sea, ferries and cruise ships switch to their own satellite networks. EU price caps don't apply there, and charges on a home SIM are usually high. Your kimsim line won't use them. Keep roaming off on your home line from the moment you board.

The networks your plan uses are listed above.

Region by region

• UK, Ireland and Gibraltar: all covered. Ireland and the UK are outside Schengen, so you'll go through passport control again between them and the mainland.
• Western Europe: France, Belgium, the Netherlands, Luxembourg, Germany, Austria, Switzerland and Liechtenstein. Monaco isn't covered, though you'll pass it on the Riviera.
• Southern Europe and the islands: Spain, Portugal, Italy, Malta, Greece and Cyprus. Andorra, San Marino and Vatican City aren't on the list.
• The Nordics: Denmark, Sweden, Norway, Finland and Iceland. The Faroe Islands and Åland aren't covered.
• Central and Eastern Europe: Poland, Czechia, Slovakia, Hungary, Romania, Bulgaria, Estonia, Latvia and Lithuania. Ukraine and Moldova aren't covered.
• The Balkans: Croatia and Slovenia are covered. Serbia, Montenegro, Bosnia and Herzegovina, Albania, North Macedonia and Kosovo aren't. A day trip from Dubrovnik to Kotor or Mostar is the classic surprise: add a Montenegro eSIM or a Bosnia and Herzegovina eSIM.
• Not Europe on this plan: for Türkiye, the Europe and Turkey plan covers both on one eSIM, or there's a Turkey eSIM on its own. Morocco needs a Morocco eSIM.

The Schengen area is 29 countries: 25 EU states plus Iceland, Norway, Switzerland and Liechtenstein. Bulgaria and Romania were the last to join, on 1 January 2025. All 29 are on this plan.

Trains, ferries and flights

• Eurostar links the UK with France, Belgium, the Netherlands and Germany through the Channel Tunnel. Download your ticket before you board, in case signal drops in the tunnel.
• High-speed trains such as the TGV, ICE and Frecciarossa cross borders without stopping. Signal can drop in cuttings and tunnels. The Gotthard Base Tunnel under the Swiss Alps is 57 km long, so expect a gap of several minutes there.
• Budget flights are often the quickest way between regions. Keep boarding passes in your phone's wallet, not only in an app that needs a connection.
• Ferries to the Greek islands, across the Adriatic or over to Ireland work on land networks near the coast. In open water, see the note on satellite networks above.

Apps worth having

• Ride-hailing: Uber works in most big cities, including Rome. Bolt is in cities such as London, Paris, Lisbon, Warsaw, Prague and Tallinn. FREENOW books taxis in about 180 cities in nine countries, and Lyft now owns it. Set accounts up at home, because sign-up can send a code to your usual number.
• Maps: download offline areas for the Alps, Iceland and any island you're visiting.
• Rail: use the national operator's app or a booking app for tickets, and save them offline.
• Payments: contactless card and phone payments are widely accepted. Some banks send a text code to approve a new device, so keep your home line on for texts.
• WhatsApp is how many hosts and guides message you. Keep your WhatsApp number working abroad.

SIM and phone rules

Many European countries make you prove who you are before a prepaid SIM works. In Germany, prepaid providers must check your passport or ID card before they switch the line on. In Spain, operators must keep a register of the identity of everyone who buys a prepaid card. France's Orange Holiday must be registered within 30 days or the line is suspended.

A travel eSIM installed at home skips the shop queue and the paperwork. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Assuming "Europe" means every country on the map. Monaco, Montenegro and Türkiye aren't on this plan. Check every stop against the list. How regional plans work
• Leaving Data Roaming on for your home line. That's where daily charges start. Roaming goes on for the kimsim line only. Why roaming goes on for the kimsim line only
• Starting the plan on a stop-over. A change of planes in London or Frankfurt is inside the plan's area, so the days can start there. Keep the line off until you arrive. If your plan started early
• Using a home SIM on a ferry or cruise. Satellite networks at sea aren't capped. When to use Airplane Mode
• No way to call for help. 112 is the emergency number in every EU country, but a data-only eSIM can't dial it. Use your home line or any local phone.

How we put this page together

We checked carriers' roaming price pages, EU and UK government sites, airport and transport operators' pages and the other sources noted above on 1–2 November 2026. AT&T's and T-Mobile's pages block automated checks, so we read their prices from the pages' search listings. We haven't measured speeds or coverage ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
