eSIM for Europe: a guide for US, Canada and Australia

Yes: for most travellers from the US, Canada and Australia, an eSIM for Europe is the cheapest straightforward way to stay online, especially across several countries. Europe's free roaming rules only cover European SIMs, so your home plan usually charges a daily fee. One regional eSIM covers dozens of countries for a fixed price.

You're probably planning a trip that crosses borders: London, Paris, the Alps, Italy. Your carrier's international page quotes a daily rate, and you're wondering how that adds up. It adds up quickly: Verizon's TravelPass is $12 per line per day in most countries, which comes to $168 per phone over two weeks.

Below: what roaming costs from each home country, which European countries a regional plan does and doesn't cover, how border crossings work, and setup step by step. Then a worked five-country example and the mistakes worth avoiding.

Do you need an eSIM for Europe?

You need one if your home plan doesn't include Europe and you want mobile data without paying a daily roaming fee. That's the case for most US, Canadian and Australian travellers. If your plan already includes the countries you're visiting, you may not need anything, so check first.

Europe is confusing because it has excellent free roaming, just not for visitors. The EU's "roam like at home" rules let people with an EU plan use it in all 27 EU countries plus Iceland, Liechtenstein and Norway. The rules run until 2032, and Ukraine and Moldova joined the area on 1 January 2026.

None of that helps a phone plan from New York, Toronto or Sydney. Your carrier's own international rules apply instead. The same FAQ adds that the rules don't apply to travel to the United Kingdom, which matters if your trip mixes the UK with mainland Europe.

What does roaming in Europe cost from the US, Canada and Australia?

As of November 2026, Verizon charges $12 per line per day in most of Europe, and Telstra charges AU$10 a day. Canadian carriers charge roughly C$16–17 a day or sell multi-day Europe passes. Prices depend on your plan, so check your own.

What a daily fee costs over a whole trip

Here's our own arithmetic: each published daily rate multiplied by the number of days, for one phone. It assumes your phone connects every day, which it will if roaming is left on.

The multi-day passes change the picture for Canadians: Rogers and Bell both list a 14-day Europe pass at C$70. That's a reminder to compare your carrier's best pass, not just its daily rate, against an eSIM's price for the same trip.

Two details make the real bill higher than it looks:

1. It's per phone. Verizon's price is per line, so two phones on a 14-day trip is $336 by our arithmetic.
2. Background data counts. Verizon says background activity such as app refreshes can start a session once data roaming is on. Telstra's terms say turning roaming off part-way through a day doesn't cancel that day's charge.

A travel eSIM is one price for a set amount of data or set number of days, shown on the plan page before you pay.

Does one eSIM work in every European country?

No single plan covers every country in Europe. A regional eSIM works in every country on its list, and only those, even if the country you're in is right next door. Our two Europe plans cover the EU and its close neighbours, and one adds Turkey and several countries outside the EU.

What our two Europe plans cover

As of November 2026, the live coverage lists are:

• Europe (33 countries): Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Gibraltar, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
• Europe and Turkey (41 countries): everything above, plus Turkey, Serbia, North Macedonia, Ukraine, Jersey, Guernsey, the Isle of Man and the Åland Islands.

Where travellers get caught out

This is our own check of the places visitors often add to a Europe trip, against those two lists:

Monaco catches people out because it sits right next to Nice, yet it isn't on either regional list, so plan for it separately or use Wi-Fi there. The same goes for a day trip from Croatia into Montenegro or Bosnia.

Open the plan page, look for Works in N countries, and check the list against your itinerary, including stop-overs. Not sure? Ask us with your list of countries before you buy. How regional plans work.

Which Europe eSIM should you choose?

Choose coverage first, then the type of data. Coverage is about which countries you'll be in; data type is about how heavily you'll use your phone. Coverage is the choice that can leave you offline, so get it right first.

Our decision guide

Answer these in order and stop at the first yes:

1. Does your home plan already include every country on your route? You may not need anything.
2. One country only? A single-country plan, such as France, Italy or Spain.
3. Turkey, Serbia, the Channel Islands or the Isle of Man on the route? Europe and Turkey (41).
4. Anywhere else in the 33-country list, across more than one country? Europe (33).
5. Albania, Montenegro, Bosnia, Monaco or Andorra? Add that country's own plan, or rely on Wi-Fi there.

Regional or single-country?

A regional plan is simpler for a multi-country trip: one install, one data balance, and no new eSIM at each border. A single-country plan suits a trip that stays put, such as two weeks in Italy, or a country neither regional list covers.

A few things differ between the two:

• Networks. The partner networks can differ from country to country on a regional plan. Each plan page lists them, with 4G or 5G next to each one.
• Plan types. The choice of fixed, Unlimited and Day Pass plans varies by destination, so compare the pages for your countries.
• Mixing them. You can hold more than one eSIM on most phones. A regional plan for the main trip plus a small plan for a side trip to Monaco or Montenegro works fine; switch the data line when you cross.

Spending most of the trip in one country? Our France, Italy and Switzerland pages go into local detail.

Fixed data, Unlimited or Day Pass?

At 1 Mbps, maps, messages, email and music work, but HD video doesn't. As of November 2026, Europe (33) offers Unlimited plans, while Europe and Turkey (41) offers fixed data and Day Pass plans. Every plan shows its after-cap speed before you pay. What Unlimited and Day Pass mean, or read what "unlimited" really means.

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

As a rough guide, two weeks of maps, messaging and some social media comes to around 6–14 GB, built from the activity figures below. Video calls home, streaming and hotspot use push it much higher. Europe's compact, walkable cities and plentiful Wi-Fi often keep usage lower than you'd expect.

Rough figures by activity (they vary by app, settings and network):

How that turns into a Europe trip:

Long train journeys are the exception to "Europe uses less". Hours of streaming to pass the time eat through a plan fast, and tunnels interrupt it anyway. Download shows and playlists on hotel Wi-Fi before travel days. Our data guide goes deeper.

How to set up a Europe eSIM, step by step

Setup takes about ten minutes at home and two switches when you land. Doing it before you travel means you're online in the arrivals hall instead of searching for airport Wi-Fi.

Before you fly

1. Check your phone. Type *#06# into the dialler. A number labelled EID means your phone supports eSIM. Or use the phone check.
2. Check it's unlocked. Apple says to look under Settings → General → About, where "No SIM restrictions" next to Carrier Lock means it's unlocked. On Android, ask your carrier if unsure. More on compatibility.
3. Buy your plan and install it on home Wi-Fi. Guides for iPhone, Samsung and Pixel.
4. Rename the line to "kimsim Europe" or similar. How.
5. Leave the kimsim line switched off. Your plan starts when it first connects in any covered country. A connection in Frankfurt or Amsterdam on the way to Rome would start the clock early. My plan started before I arrived.

When you land

1. Switch the kimsim line on and choose it for mobile data. Choosing the data line.
2. Turn Data Roaming on for the kimsim line only. The eSIM connects as a visitor, so this switch must be on. kimsim is prepaid, so you won't be charged roaming for it. Turn on Data Roaming (and why it matters).
3. Turn Data Roaming off on your home line. That stops background data starting your carrier's daily fee.
4. Decide about calls and texts. If you want your usual number reachable, keep the home line on for calls and texts. Calls and texts.

What happens when you cross a border?

Usually nothing you need to do. When you cross into another country on your plan's list, your phone drops the old network and connects to a partner network in the new one, typically within a few minutes. It's the same eSIM and the same data balance throughout.

If the phone doesn't pick up a network:

1. Turn Airplane Mode on and off once. This makes it search again.
2. Choose a network by hand from the plan's list, then switch back to Automatic later. How.
3. Check the country is on the list. If it isn't, the eSIM won't connect there however long you wait.

Stop-overs and when your plan starts

A regional plan starts the first time the eSIM connects to a network in any country it covers. That's usually when you land, but it can be earlier. If you change planes in London, Frankfurt or Amsterdam with the kimsim line switched on, the plan can start there, a day before your trip proper.

The fix is simple: keep the kimsim line switched off until you arrive at your first real destination, then turn it on. If you think a plan started at the wrong time, talk to us with your order number and we'll check the activation time with the network. More on early starts.

Trains, tunnels and mountains

High-speed rail runs through long tunnels and deep cuttings, so expect gaps on the way. Download tickets, boarding passes and offline maps before you board. Mountain valleys in the Alps and smaller islands can be patchy between towns on every network, so save offline maps for those too.

Ferries

Ferries between countries can lose land signal mid-crossing. Some ships run their own onboard mobile network, which a travel eSIM doesn't cover and your home carrier may bill separately. Keep Data Roaming off on your home line on board, or use Airplane Mode with the ship's Wi-Fi.

Will you get a European phone number?

No. kimsim plans are data only, so you get mobile internet but no European number, calls or texts on the eSIM line. For most visitors that's fine: messaging and calling apps keep running on your usual number over data, and your home SIM can stay on for calls and texts.

• WhatsApp, Telegram, Signal. Nothing to change, and don't re-verify your number. WhatsApp and iMessage, or our WhatsApp guide.
• iMessage and FaceTime. Check your usual number is ticked under Settings → Messages → Send & Receive.
• Bank codes by SMS. These arrive on your home SIM if that line is on. Check your carrier's rules first, since Verizon counts receiving a call or sending a text as using your phone abroad.

Emergency calls: dial 112

The EU's single emergency number is 112. The European Commission says it's available everywhere in the EU, free of charge, from fixed and mobile phones. The kimsim eSIM is data only, so if you keep your home SIM switched on, make emergency calls from that line as normal.

A worked example: 16 days, five countries

Suppose two people from Chicago are spending 16 days in Europe: London, the Eurostar to Paris, a train to Switzerland, then Milan and a week in Croatia. Both are on Verizon, and both use their phones for maps, messaging, photos and a few video calls home.

1. Coverage. UK, France, Switzerland, Italy and Croatia are all on the Europe (33) list, so one Europe (33) plan each covers everything.
2. Data. Sixteen days of medium use, with video calls. That points to a large fixed plan or Unlimited.
3. Watch the detour. A day trip from Dubrovnik into Montenegro or Bosnia would fall outside the list. They'd add a small plan for that country or stay on Wi-Fi.
4. Install. At home on Wi-Fi a week before. Rename the lines and leave them off.
5. Land at Heathrow. Switch the kimsim lines on, set them for data, Data Roaming on for kimsim and off for Verizon. The plans start now.
6. Cross borders. On the Eurostar and the Swiss trains, the phones move between partner networks on their own, with gaps in tunnels.

For comparison, TravelPass at $12 per line per day for 16 days would be $192 per phone, or $384 for the two of them, by our arithmetic.

Common mistakes with a Europe eSIM

Most Europe eSIM problems come from a handful of avoidable slips. Here they are, with the fix for each.

How we put this guide together

We checked roaming prices on 1 November 2026, on Verizon's and Telstra's own pages. AT&T's site blocked our check, so its figures come from a third-party plan guide. Canadian figures come from iPhoneInCanada's reporting. We also used the European Commission's roaming and 112 pages and Apple's eSIM support pages.

Coverage lists come from our live catalogue on the same date. Facts about kimsim plans come from our own help centre. We didn't test networks country by country ourselves.

kimsim sells travel eSIMs, including the Europe plans mentioned here. Prices and coverage change, so check your carrier's app and the plan page before you travel.
