Best eSIMs for Europe 2026

Europe is the easiest continent on earth to stay online in, and also the one where people most often overpay for data they did not need. The reason is that the right answer depends almost entirely on which SIM you already carry. So before any picks, one question: where is your phone contract from?

If it is from an EU or EEA country, you probably don’t need anything in this article. The EU’s Roam like at home rules let you use your domestic allowance across the EU plus Iceland, Liechtenstein and Norway without surcharges, subject to fair-use limits. The European Commission’s own roaming Q&A is the place to check the detail. The two exceptions that catch people out: the UK and Switzerland are not part of the scheme, so an EU contract may charge there, and a UK contract may charge you in the EU.

For everyone else, including most people flying in from Africa, the Americas, Asia and the Gulf, a travel eSIM is usually the cheapest sensible way to land with working data.

How we judged

We looked at each provider’s own product and help pages (linked throughout) and scored them on five things that actually change your trip:

1. Plan model. Fixed gigabytes, “unlimited” by the day, or a recurring subscription. This decides whether you’ll be topping up in a queue at the Louvre.
2. Hotspot rules. If you travel with a laptop or a partner whose phone lacks eSIM, tethering limits matter more than headline speed.
3. Phone number. Most travel eSIMs are data-only. That’s fine for WhatsApp and bad for banks that insist on SMS codes.
4. Coverage list. “Europe” means different things to different providers. The Balkans, Turkey and the UK are where lists diverge.
5. Fair-use honesty. Whether the throttling rules are written down in plain language on the provider’s own site.

We deliberately include providers we have no commercial relationship with. The partner links below are marked; nothing about the ranking depends on them.

Airalo: the default for most trips

Airalo Partner is the one we’d hand to a first-timer. Its Europe regional eSIM lists 41 countries and networks, and the store lets you filter between fixed-data packs and unlimited plans sold by duration.

The unlimited plans are the interesting part because Airalo actually spells out the catch. Its fair use policy says that after 3GB in a day, speed drops to 1 Mbps for the rest of that day, and it states that there is no limit on tethering or the number of devices you connect. Its help centre confirms hotspot works as long as your device and the network support it.

Best for: multi-country trips where you want predictable rules and a laptop hotspot. Watch for: the Europe plan is data-only. Airalo does sell some “Data, Voice & Text” eSIMs elsewhere in its range, per its calls and texts help page, but don’t assume the regional Europe plan includes a number.

Holafly: unlimited by the day, with a hotspot ceiling

Holafly Partner sells Europe plans as unlimited data priced by number of days, covering 33 countries on its list. It’s the “don’t make me think about gigabytes” option, and for people who stream, video-call or navigate heavily on their phone alone, that simplicity is worth something.

The limits are on the same page if you look. Holafly says the eSIM does not include a local phone number, that hotspot sharing is capped at 1GB of data per day, and that speed may be reduced temporarily under heavy use to manage network traffic. It also notes coverage can be limited in rural and mountainous areas, which is honest and applies to every provider on this list.

Best for: solo travellers who live on their phone and don’t tether. Watch for: if you plan to run a laptop off your phone for a working day, 1GB goes quickly.

Saily: generous sharing, from the NordVPN stable

Saily is run by Nord Security, the company behind NordVPN, and it is not one of our partners. Its Europe page lists 35 countries and plans from 1GB up to unlimited. The unlimited tier gives 3GB a day without a speed limit and reduced speed after that, which in practice is similar to Airalo’s approach.

Where Saily stands out is hotspot policy: the page says you can share as much of your hotspot as you like. It also bundles an ad blocker and a virtual location feature into the app. Like the others, it’s data-only, and the page recommends WhatsApp, Signal or Viber for calls.

Best for: couples or families sharing one connection. Watch for: 35 countries is fewer than Airalo’s list. Check your specific countries, especially outside the EU.

Ubigi: the operator-grade option

Ubigi is run by Transatel, a Paris-based MVNO enabler that is part of the NTT Group. It is not a partner. Its help centre describes one-off data plans, recurring “Ubigi Monthly Plans” you can cancel any time, and unlimited offers that may be slowed after a certain usage. Tethering is supported with instructions for iOS, Android and Windows.

The monthly plan model is the reason to consider it. If you spend part of every month in Europe, keeping one eSIM profile and a rolling plan is less faff than buying a new pack for each trip. Ubigi also supports tablets, laptops and some connected cars. We couldn’t confirm a Europe-specific country count or phone-number policy from its current pages, so check before buying.

Best for: frequent visitors and anyone who wants the same eSIM in a laptop.

When a local SIM wins

eSIMs are convenient, not always cheapest. A local prepaid SIM (or local eSIM) tends to beat every option above when:

• You’re staying a month or more in one country. Domestic prepaid bundles are built for residents and can be far better value than any regional travel pack. Bonus: an EU local SIM then roams across the rest of the EU under the same Roam like at home rules, subject to operator fair-use terms.
• You need a local number. Restaurant bookings, delivery apps, some banks and ride-hail services want a local mobile number.
• Your phone doesn’t support eSIM or is carrier-locked.

The trade-off is friction on arrival: shop hours, ID registration in some countries, and possibly a shop in a language you don’t read. If you land late at night, a travel eSIM installed before departure is still the better first 48 hours.

Setup checklist

Do this at home, on Wi-Fi, not at the baggage belt:

1. Confirm your phone supports eSIM and is unlocked. Your handset settings or your carrier will tell you.
2. Buy and install the eSIM before you fly, but check whether the plan’s validity starts on install or on first connection in the destination. Providers differ.
3. Label the lines (“Home” and “Travel”) so you don’t mix them up in settings.
4. Set mobile data to the travel line and turn data roaming on for the travel line only. Leave roaming off on your home line if you don’t want surprise charges.
5. Keep your home line active for SMS if your bank sends one-time codes by text.
6. Download offline maps for your first city, in case activation takes a few minutes on arrival.
7. If you’ll use public Wi-Fi in stations and cafés, a VPN such as NordVPN Partner is a reasonable extra layer.

Once you’re sorted, check your destination’s country page for plugs, emergency numbers and local holidays, and our trip planner to put the whole route on one screen.
