Best eSIM Options for Travelling to Europe in 2026

It's also a great place to pound pints on a Contiki tour.

Whichever camp you land in, you're going to need a mobile internet connection in Europe. Getting online is crucial for translating menus, deciphering tram timetables, and uploading Cinque Terre Instagram snaps (among other things).

Global roaming costs a bomb and local plastic SIMs are a chore. That leaves you with the eSIM - the easiest way to get connected on a Euro trip.

But not all eSIMs are created equal. To help steer you towards a good deal, we're covering 5 of the best eSIMs for Europe for Australians.

How We Compared Europe eSIM Plans

We didn't just draw names out of a hat or copy-paste generic AI overviews. Our editor (that's me) manually researched the most important eSIM metrics, including coverage, costs, installations, support, feedback scores, and more. We then graded each eSIM using a weighted, multi-criteria scoring model to sort the wheat from the chaff.

Top eSIM Providers for Europe Compared

Here's where we break down each eSIM, including the fine print hidden deep in their T&Cs.

Despite its unceremonious exit from the EU, all these Europe eSIMs do include the UK. If you're just visiting Britain, you may prefer a cheaper UK-only eSIM.

ZenSim: Best-Value eSIM for Europe

An eSIM company from Australia, ZenSim is boldly battling the big eSIM brands by offering top-tier features at a low-end price.

Covering 40 European nations, the ZenSim Europe eSIM offers a seamless connection across most of the Old Continent, perfect for backpackers, road-trippers, or luxury river cruisers leapfrogging across countries.

Managing your plan is a cinch thanks to the ZenSim app, where you can monitor consumption and top-up data, destinations, or days. Unlimited users will appreciate the transparent 3GB/day use cap, which removes guesswork from data management.

ZenSim includes unlimited hotspotting, perfect for laptop-wielding digital nomads and evening TV streamers. Its customer support team is staffed by native Australians around the clock and responds rapidly.

ZenSim also has the most generous refund policy in the business. Customers can return their eSIM for any reason pre-departure and receive a 100% refund. The only condition is that you must have purchased it within 90 days.

One unique ZenSim feature is the destination top-up. If you're planning a stopover in Dubai, for example, you can add the UAE to your European eSIM instead of buying a new one - it's much less hassle.

All this has seen ZenSim earn an industry-leading 4.9/5 stars on ProductReview, with customers praising its reliability and speeds.

Airalo Europe eSIM: Best Destination Coverage

One of the world's largest and oldest eSIM brands, Airalo is a popular Singapore-based eSIM with international appeal.

Airalo boasts a simple, easy-to-use mobile app, which works in 53 languages and accepts multiple currencies. This global approach has helped Airalo build a worldwide customer base exceeding 20 million.

The Airalo Europe travel eSIM spans numerous sizes and price tiers, with plans to suit varying needs. Prices at the 10GB and 20GB mark are significantly higher than ZenSim, though its unlimited eSIM is more competitive.

The Airalo Europe eSIM includes 41 countries and destinations, which is more than most other eSIMs. Just note that one destination is Gibraltar, which may or may not be on your bucket list. Nonetheless, Airalo includes a bunch of Eastern European and Balkan countries on its standard Europe eSIM, which many competitors offer separately.

Customers enjoy hotspotting and a clear 3GB/day usage cap on unlimited plans. In-app top-ups and installations are fast and easy, and Airalo has a dedicated 24/7 support team.

Airalo only has a 4.0/5 Trustpilot score, which suggests quite a few punters have problems with the platform. Most negative reviews we read complain about sluggish connections.

Holafly: Best for Back-up Data

Holafly is a large, Spanish-born multinational serving over 13 million customers in 160+ destinations, including Europe.

You've probably seen Holafly recommended online through its affiliate program. Seemingly 'impartial' bloggers, YouTubers, and influencers recommend the eSIM in exchange for a slice of its affiliate sales.

This prolific online presence means Holafly can charge more than the competition. For example, the standard 30-day unlimited plan costs around 20% more than other competitors on our list.

Note that the 33-country Holafly Europe eSIM doesn't cover much of Eastern Europe, which is sold separately. Also, its daily use cap is hidden behind a 'Fair Use Policy,' meaning the local network will decide when to throttle you.

Another Holafly downside is the 500MB/1GB hotspotting limit. You might want to look elsewhere if you plan on tethering your laptop to your phone.

On the plus side, Holafly lets you choose and pay for the exact number of days you need to whittle down the final cost. You can't top-up, though, so expect to buy a whole new plan should you extend your trip.

Setup is straightforward enough, even though direct installs aren't available, and Holafly offers solid 24/7 support through live chat, email, and WhatsApp.

Holafly has a neat 'always-on' feature, where you can get limited data year-round, even without an active eSIM - it could come in handy as backup data. The brand does well on Trustpilot, with a 4.7/5 rating.

Nomad Europe eSIM: Best Sales

Based in California, Nomad is an American tech startup and Mobile Virtual Network Operator (MVNO) that's branched out into travel eSIMs.

The Nomad Europe eSIM does things differently, offering two separate plans. Punters can choose between a cheaper, classic EU eSIM with 35 destinations, and a pricier 36-country eSIM that includes Turkey, the Canary Islands, and Northern Cyprus.

Short 5-day and 10-day unlimited plans (Nomad mostly caters to Americans) are available on the 35-country eSIM only. Otherwise, you're looking at fixed-data plans, ranging anywhere from 1-50GB. Periodic sales can drop prices by around 20%.

Nomad has a slick, user-friendly app for hassle-free installations (direct and QR code installs available), easy top-ups, and contacting support. The eSIM also has a great refund policy, offering a 100% money-back guarantee on all pre-departure returns for any reason (similar to ZenSim), provided it's within 30 days of purchase.

Nomad has a less-than-stellar 4.3 Trustpilot score.

Saily Europe eSIM: Best for Security

Chicago-based Saily is a well-established travel eSIM brand from NordSecurity, the same mob responsible for NordVPN. Somewhat unsurprisingly, the Saily Europe eSIM bundles in a bunch of cybersecurity tools, including an ad-blocker, browsing protection, and virtual location spoofing.

Security-conscious travellers might find these perks offer value. But for everyday Australian holidaymakers in Europe, they could be a bit overkill, especially given Saily commonly costs a smidgen more than the competition.

That said, Saily does occasionally run specials and promo codes, and offers discounts to verified students.

Europe unlimited plans have a daily cap of 3GB/day before throttling, and hotspotting is not restricted. The Saily app runs silky-smooth and allows you to top-up days, dates, and destinations on the fly.

As you would expect from a well-established eSIM, Saily operates a 24/7 support centre through email or live chat via the app.

Despite the higher prices, the brand consistently scores decent feedback, with a Trustpilot score of 4.7/5.

Europe eSIM Plans Comparison Table

We've compiled the key info into a neat little table so you can compare our leading Europe eSIMs side by side.

Pricing, inclusions, and exchange rates are subject to change.

How Much Data Do You Need for Europe Travel?

Would a cheap-and-cheerful data-capped plan suffice? Or should you spend the extra euro on unlimited?

It depends on your day-to-day data habits.

Personally, I'm fairly digitally thrifty when I travel, saving most of my data-heavy sessions (streaming, doomscrolling, etc.) for local WiFi. By following the usual data-saving best practices, I find 20GB enough to get through a month in Europe.

Not everyone is like me, though. Social media addicts may want unlimited data to find travel inspo and share their adventures in real time.

Unlimited also makes financial sense for digital nomads and business travellers. A backup connection is a lifeline when the WiFi isn't up to speed; unlimited data lets you remain productive all day long. Just make sure your eSIM also includes unlimited hotspotting.

Also, plenty of regular, everyday tourists choose unlimited data just for the peace of mind. Travelling overseas can be stressful enough already. Unlimited means you never have to worry about running out of data in a weird foreign country.

Anyhow, to help you decide, here's a breakdown of what you can generally get away with on data-capped and unlimited plans in Europe.

Europe eSIM vs Roaming: Cost Comparison

People like eSIMs because they cost less than roaming. How much less? That depends on the roaming plan.

If you don't purchase an eligible package, your provider will charge you standard, 'Pay-As-You-Go' (PAYG) roaming rates. Trust me when I say you don't even want to consider this option. I've seen 'casual' rates as high as $1/MB, which equates to $1,000/GB. An eSIM could easily be hundreds of times cheaper.

Most Mobile Virtual Network Operators (MVNOs) offer prepaid roaming packs, though they're still pretty pricey compared to eSIMs.

We actually do prepaid roaming here at ZenSim too, but we don't bother telling people because our travel eSIMs offer much better value. That's universally true. Allow me to demonstrate.

When you break it down by dollar per GB, the ZenSim Europe travel eSIM works out way better value than any prepaid roaming plan we've seen. In some cases, it's literally 5x cheaper.

To be fair, prepaid isn't the only global roaming option. Customers of Australia's three hosted networks (Telstra, Optus, Vodafone) might be able to access more affordable 'Day Passes.' I say 'might' because these deals are only available to users on select plans.

At A$10 for just 2GB per day, the Telstra Day Pass is dear. No two ways about it.

Optus and Vodafone offer better value at A$5 per day, the former including a decent 5GB/day. That sounds cheap on paper, but spread over a month, you're looking at A$150. For comparison, the ZenSim 30-day Europe unlimited plan is only A$99 - and that's for unlimited data.

As you can see from the next table, the Optus and Vodafone $5 roaming plans make financial sense for eligible customers doing short trips of 5 days or less.

Of course, no sane Australian would willingly travel to Europe for 5 days or less, given it takes 24 hours of gruelling non-stop travel to get there.

For longer stays, travel eSIMs like ZenSim work out cheaper than Day Pass deals. The cost gap widens significantly when you compare month-long trips or cheaper data-capped plans.

The Global Roaming PAYG Trap

Your telco won't switch you to PAYG rates once you run out of data on a roaming plan. But that's only because the ACCC won't let them. The regulator recently cracked down on predatory PAYG roaming in a major, decade-long legislative update.

However, the insidious PAYG trap - where customers unknowingly use data at exorbitant PAYG rates - hasn't been stamped out entirely. Aussies can still inadvertently cop outrageous 'standard' roaming rates when using their home SIM in certain situations:

• You switch on roaming before activating a roaming plan.
• You pass through an uncovered country (common with airport layovers or long-distance train trips).
• You travel close enough to an uncovered country for your phone to connect to a tower.
• Your phone connects to a cruise ship maritime or in-flight aerospace network, which isn't covered in roaming plans and incurs crazy-high PAYG rates. Remember, you don't need to actively use your phone to trigger PAYG roaming. Even minor background downloads could cost you hundreds or thousands of dollars. Don't mess this up.

So how can you protect yourself from such stressful PAYG trap shenanigans? The safe solution is to use a Europe travel eSIM and turn off roaming on your Australian SIM entirely.

Choosing the Best eSIM for UK and Europe Trips

First time getting an eSIM? From costs to coverage and customer support, here's what to consider when choosing an eSIM for Europe and the UK.

Coverage

Coverage is crucial in Europe, where you're constantly hopping across borders. If one country you're visiting isn't included on your plan, you'll need to buy a separate eSIM at a considerable extra cost.

Don't just look for the eSIM with the most destinations. Compare your itinerary against the included countries to look for gaps (AI is handy here). ZenSim is unique in offering destination top-ups, where you can add new countries to an existing eSIM.

Partner Networks

The best eSIM cards for Europe partner with top-tier local networks to provide fast, reliable connections across the entire continent. Local networks vary by country, so choose an eSIM provider with a strong track record. Not familiar with multi-network connections? They let your phone automatically choose the fastest available network.

Online Ratings

Online reviews indicate how well an eSIM performs in the field. Compare the average feedback score on aggregate review sites like Trustpilot and ProductReview to see which eSIMs excel. I like to sort reviews by lowest ratings to understand what issues I might encounter with a specific provider.

Data and Validity Flexibility

Look for a provider that lets you choose from a wide range of data size packages (e.g., 2GB, 3GB, 5GB, 10GB, 20GB, 40GB, Unlimited) and duration validities (e.g., 5-day, 15-day, 30-day). More variety means you won't pay more than you have to for data or days you won't use.

Hotspotting and Tethering

If you plan to tether your laptop to your phone, look for an eSIM with unlimited hotspotting. This feature is a non-negotiable for business travellers and digital nomads clocking hours on the road, as well as anyone planning to stream TV or other media. Thankfully, it's becoming increasingly common among eSIMs.

In-App Top Ups

You don't want to run out of data in bumf*ck Bratislava. In-app top-ups let you instantly add extra data or extend trip duration, even after you've exhausted your allowance. Some eSIMs (à la ZenSim) even let you add new destinations to an existing plan.

Easy Installations

The eSIM is meant to be easy. Top providers offer at least three hassle-free installation options (direct, QR code, manual), each taking less than 5 minutes to complete - if one doesn't work, move on to the next. The leading Europe eSIMs send step-by-step instructions via email.

Daily Use Cap (Unlimited Plans)

Unlimited users must consider daily use caps. After downloading your daily data limit (typically 3GB), your connection gets throttled to 1 or 1.5 Mbmps, enough for basic browsing but not high-res video streaming. Some brands hide the cap within a 'Fair Use Policy.' That's far from ideal, as you'll never really know when you'll get throttled.

Customer Support

The best eSIMs for Europe travel offer round-the-clock support via online channels like WhatsApp or live chat. I reckon online support is a must-have. You really don't want to be hunting down a traditional phone (nor waiting on hold) while visiting some middle-of-nowhere town in rural Croatia.

Refund Policy

Can you get a refund if you cancel or change your travel plans? What if you accidentally bought an eSIM you can't use on your non-eSIM-compatible phone? Some eSIM providers will leave you out of pocket. Others, such as ZenSim, offer a 100%, no-questions-asked refund for any reason before departure.

Sales & Discounts

Some eSIMs offer flash sales or ongoing discounts that can heavily affect the price and value. Keep a keen eye out for promo codes and return- or bulk-buy discounts. ZenSim offers a flat 10% off for every repeat customer or group purchase (two or more eSIMs).

Unique Perks

Some eSIMs offer unique benefits: Saily includes cybersecurity tools; Jetpac offers lounge access for delayed flights; and Holafly runs an 'always-on' promotion. At ZenSim, we offer destination top-ups so customers can add extra countries (fancy a Singapore stopover?) without buying a whole new eSIM.

eSIM Size and Origin

Larger eSIMs have bigger budgets to cover marketing, support, and sales. But cost blowouts can drive up prices, and many big players charge a premium based on brand recognition alone. We've included country of origin as plenty of Australians prefer supporting local businesses rather than foreign-owned multinationals.

How to Activate Your Europe eSIM

Setting up a Europe eSIM is a cinch. Here's everything you need to do.

1. Confirm your phone supports the tech with our eSIM compatibility checker.
2. Shop around to find the best-value eSIM for your needs.
3. Purchase your eSIM directly from the provider's website.
4. Install your eSIM before departure via one of three options (varies by provider).
   1. Direct install: Hit the 'INSTALL ESIM' button on the app for a one-tap installation (best non-QR code installation option).
   2. QR Code: Open your purchase confirmation email on a different device (e.g., a laptop), scan the QR code with your phone, and follow the prompts.
   3. Manual: Copy-paste a code from your confirmation email into your phone's eSIM settings.
5. Activate the connection upon arrival by making the travel eSIM your active mobile data line and switching global roaming on (for the travel eSIM only).
6. Enjoy instant data upon touchdown and a seamless mobile connection throughout Europe.

Installing and Activating Your Europe eSIM

Installation and activation mean two different things.

Installation is setting up the digital SIM profile on your phone, using one of the options mentioned above. I always recommend doing this before departure, preferably at home because you need a decent WiFi connection. Besides, a pre-departure install gives you a seamless connection and one less thing to worry about on arrival.

Activation is when the clock starts ticking on your data allowance and validity (30 days, 15 days, etc.). Different eSIMs trigger this event in different ways. Some activate immediately upon installation, meaning the days start counting down straight away. Others activate on a pre-selected date, which gets messy when changing travel plans.

At ZenSim, our eSIMs activate automatically when they connect to a mobile tower in a destination country, typically when you arrive at a European airport. We chose automatic activation as the most convenient, customer-friendly option.

For your eSIM to communicate with a local tower, you must configure two settings on your phone.

1. Your Europe travel eSIM is the active mobile data line.
2. Global roaming is switched on for the travel eSIM. I usually do this final step on the flight to Europe, or shortly after touchdown.

Best eSIM Plans for Europe by Traveller Type

There's no universal, set-in-stone best Europe eSIM for everyone. The ideal provider and plan often boils down to your specific needs. Here's what certain traveller types might choose to prioritise when comparing eSIMs.

Backpackers and Budget Travellers

Backpackers exploring on a shoestring want the cheapest eSIMs for Europe. Affordable data-capped plans, low per-GB costs, and discounts or sales can help budget travellers save.

• Affordable, low-per-GB deals
• Data-capped plans
• Discounts and promotions

Business Travellers

Travelling professionals prioritise reliability, coverage, and speed. The top Europe eSIMs list partner networks for each included country, so you can confirm local network quality at your main destinations. Unlimited plans eliminate the risk of running out of data mid-trip.

• Quality partner networks
• Broad coverage
• Unlimited plans

Families and Couples

Small groups can save money by sharing a connection, which means unlimited hotspotting and a high data allowance are a must. Alternatively, some eSIMs (such as ZenSim) offer discounts for multiple eSIM purchases, making individual connections more economically appealing.

• Unlimited hotspotting and high-data plans for shared connections
• Group discounts for individual connections

Digital Nomads

Digital nomads typically stay longer in one place than other tourists, meaning most prefer longer-validity 30-day plans. Since they're working from a laptop, unlimited hotspotting is non-negotiable. Many nomads venture into other global regions, such as Latin America or Asia, so it's handy to have an eSIM with broad worldwide coverage.

• Longer duration plans
• Unlimited hotspotting
• Broad global coverage

How do I activate an eSIM before travelling to Europe?

Typical eSIM installation options include direct installs, where you tap a button in the app; QR code installs, where you scan the QR code on a separate device; and manual installs, where you copy and paste a code into your phone's eSIM settings. Each takes under 5 minutes and should ideally be done before departure. Upon arrival, activate your eSIM by setting it as the active mobile data line and switching on global roaming (for the eSIM only).
