Best eSIM for Europe: Our 5 Picks for Travelers (2026)

Today, you’ll find the best eSIM for Europe, and we know you’re excited. Europe is a diverse, multicultural continent with 44 countries. If you’re on a European haul, you need an eSIM that covers most of it. However, you also want an eSIM with 5G connections, and possibly unlimited internet data for worry-free browsing.

During our testing for the best eSIM for Europe, we considered these factors, but we added value for money, ease of use, and customer support. So, after retesting 20+ eSIM services across at least ten major countries in 2026, we stuck with the five below. They’re convenient, cheap, and reliable.

Best eSIM for Europe: Our Detailed Reviews for 2026

We compared all five on country coverage, price, unlimited data, tethering and plan length. The gaps are bigger than the marketing suggests, especially once you leave Western Europe.

1. Ubigi

Ubigi is the cheapest, most reliable eSIM for Europe, starting at only $2 for 500 MB of data. Its coverage spans the continent, and the Europe Extended plan adds the United Kingdom, Uzbekistan, Turkey, and the Balkans. Ubigi also sells annual, monthly, and one-off plans.

For unlimited data, you’ll spend $69 for 30 days or $26 for a week. The extended version runs $99 for 30 days and $49 for seven. Ubigi offers 3G, 4G, and 5G coverage, with exceptional speed and stability, and even the standard plan supports 37 countries.

Check Ubigi’s Europe plans

Ubigi is, similarly, among the best eSIMs for the USA because of its coverage. It activates via QR code, has apps for both platforms, and permits limitless data sharing with friends or other devices. The one gap is the lack of phone numbers, which barely registers day to day.

Ubigi also lets you browse securely, choosing either a home-country IP for unrestricted access to your usual content or a local IP for a more local experience, with zero added latency. All this at 10% off on your first purchase with the code GIZMODO.

2. Saily

Saily covers 35 countries, two fewer than Ubigi, and it’s our #2 for Europe in 2026. It offers something Ubigi lacks: security tools. You get an ad blocker and a virtual location, similar to a VPN service. Prices have come down too, with 1 GB for a week now at $4.24.

The best value is unlimited data at $42.49 for 15 days, and there are longer options like the 50 GB plan for 90 days at $81.59 if you’re travelling Europe back and forth. Worth knowing before you buy: the unlimited plan gives 5 GB per day at full speed, then throttles to 1 Mbps. Ample for maps and messaging, not for streaming.

See Saily’s Europe plans

Saily’s 5G coverage is exceptional, and we had no issues during calls or video chats. It covers all the major European countries and works in the UK and Turkey, but it still lacks the Balkans. That’s the one thing to check before you buy. If Albania, Montenegro or Serbia are on your route, Ubigi Extended or Airalo are the safer choices, and we’ve ranked the best eSIM for Albania separately for that reason.

There’s more in 2026. The app now sells airport lounge access and fast-track security passes at checkout, with no subscription. Saily was named “Rising Star” at the MVNOs World Congress in Amsterdam in June 2026. One practical note: install the eSIM before you fly, since access to the Saily app can be restricted in Turkey. Current offers sit on our Saily promo code page.

3. Holafly

Holafly lets you dodge roaming costs in Europe with unlimited data from $3.90 per day, and prices fall for longer stays. A week is $27.30, a month $74.90. It’s pricier than Ubigi, but it matched it on speed, performance and reliability in our tests.

Its real edge in 2026 is that the data is genuinely uncapped, with no speed limit at any point, unlike Saily’s unlimited plan. Gaming felt smooth across most of the continent, and VoIP delivered staggering results in video and audio calls. The catch is reach: Holafly covers only 33 countries, the fewest here. It includes only Croatia from the Balkans and doesn’t officially work in Russia.

Where it does work, you’ll usually get 5G, with 4G LTE as fallback. Holafly’s support is available 24/7, activation runs through the app, and tethering is one click away. But it’s capped at 500 MB per day, and it lacks voice and SMS. Our next pick fills part of that gap.

4. Airalo

Airalo has the widest European footprint of the five, covering 42 out of 44 countries, the Balkans included. Its 1 GB plan is $4.50 for seven days, and unlimited runs $31.50 for ten days. Plans stretch to 30, 90, or 180 days if you’re really drawing out the trip.

Airalo is a leading eSIM option for global travel, and it even offers calls and SMS, though not in its regional plans. You can buy that function separately for most European countries. Airalo uses 5G and 4G networks in most of them, and we were impressed across Western Europe.

5G held up in Denmark, France, Hungary and Germany. In France it relies exclusively on 5G, which makes it a top pick there. And unlike Holafly, it allows unlimited data tethering, ideal for a group of friends or a family sharing one plan. If the Balkans are on your itinerary, it’s one of only two options here that will work, alongside Ubigi Extended, and it’s worth reading our take on what works in Montenegro before you go.

5. Nomad

Nomad is an aptly-named eSIM for Europe with affordable prices, no roaming charges, and decent coverage. Its plans reach up to 36 countries and go up to unlimited data for as little as $18 for five days. The ten-day price is low too, at $33. What Nomad is really known for is its business features.

It suits small companies sending a few employees to Europe. Nomad supports 5G across nearly all its regions, including Hungary, Austria, Poland, the UK and Iceland. We retested its speeds and they were solid, though still not at Ubigi’s or Airalo’s level.

It was fine for VoIP and occasional gaming. Nomad also offers 1 GB of free data for three days across 81 locations, with no credit card required, which remains the only free trial on this page. The main drawback is the absence of plans beyond 30 days.

How to Choose an eSIM for Europe?

Here’s what to consider when choosing an eSIM for Europe:

• Coverage. This is the first thing to check, not the last. Airalo covers 42 countries, Ubigi 37, Saily 35, Nomad 36 and Holafly 33. If the Balkans are on your route, Saily and Holafly will leave you offline.
• Trip duration. Pick a plan that matches your trip, or slightly longer. If you’re in Europe for a week, a ten-day plan buys you a safety margin.
• Amount of data. Check your daily consumption on your phone before deciding between a metered plan and unlimited.
• Throttling. Not all unlimited plans are equal. Saily’s slows to 1 Mbps after 5 GB a day. Holafly’s never slows down.
• Price. Apply the promo codes before comparing. Ubigi’s 10% and Saily’s 15% change the ranking on several plans.

The Final Verdict: Best eSIM for Europe

The best eSIM for the world and for Europe in 2026 is Ubigi. It’s affordable, reliable and flexible, and its Extended plan reaches further than anything else at this price, the Balkans included.

Saily is the standout for security, and it’s cheaper than it used to be, though the missing Balkan coverage is a real limitation on a longer trip. Holafly is the champion of unlimited data, and the only one that never throttles you. Airalo offers the widest European coverage at 42 countries. We left Nomad last, due to slightly slower connections, but the prices are hard to argue with.

All five are easy to set up and activate instantly. Pick one and make your trip epic.

Frequently Asked Questions

What is the best eSIM for Europe?

Ubigi is the best eSIM for Europe overall. It covers 37 countries, or more with the Europe Extended plan, which adds the UK, Turkey and the Balkans. Unlimited data costs $26 for a week or $69 for a month, and the GIZMODO code takes 10% off your first order. Saily is the best alternative if you want built-in security tools.

Which eSIM covers the most European countries?

Airalo, with 42 out of 44 countries. Ubigi follows with 37 on the standard plan and more with Extended, then Nomad with 36, Saily with 35 and Holafly with 33. Coverage is the single most important criterion on a multi-country trip.

Which eSIM works in the Balkans?

Ubigi Extended and Airalo. Saily does not cover the Balkans at all, and Holafly only includes Croatia. If your route takes in Albania, Montenegro, Serbia or Bosnia, those two are the ones to buy.

Are roaming charges in Europe high?

Yes, if you are travelling from outside the EU. Roaming is billed outside your domestic bundle and often leads to bill shock, since data, texts and calls are all charged at international rates. An eSIM connects you to local operators in each country you visit, at local rates.

Is 5G available on eSIM providers for Europe?

Yes, all five providers offer 5G in Europe, with 4G taking over when 5G is unavailable. Western Europe has the strongest 5G, and some countries rely on it almost entirely. In the Balkans, most connections are still 4G, which is perfectly usable.

Which unlimited plan is truly unlimited?

Holafly’s. It has no speed cap at any point. Saily’s unlimited plans give you 5 GB per day at full speed and then throttle to 1 Mbps. Ubigi sells the cheapest unlimited month at $69, and Airalo caps its unlimited plan at 10 days.
