Best eSIM for Europe Travel in 2026: Honest Comparison
I've done five Europe trips in the last two years. France, Italy, Spain, Portugal, Croatia, Greece, the Balkans. Every single time, the first thing I sort out before packing is my eSIM. And every single time, I end up re-comparing providers because the market keeps changing.
So I figured I'd just write the comparison I keep doing in my head. No affiliate links, no sponsored placements. Just what I've actually used and what my travel friends have reported back.
The Providers I Compared
These are the five names that keep coming up in every travel group and Reddit thread:
- GOAN - group-focused eSIM with a real phone number
- Airalo - the biggest marketplace
- Holafly - "unlimited" data plans
- Nomad - budget pick
- aloSIM - pay-as-you-go
I've personally used three of these. For the other two, I pulled from friends who used them on recent trips and cross-referenced with community reviews.
Price Breakdown (The Real Numbers)
This is what a Europe plan actually costs when you stop looking at marketing pages and just compare gigabytes per dollar:
| Provider | Data | Duration | Price | Per GB |
|---|---|---|---|---|
| GOAN | 20GB | 30 days | $29* | $1.45 |
| Airalo | 10GB | 30 days | $26 | $2.60 |
| Holafly | "Unlimited" | 15 days | $44 | N/A |
| Nomad | 10GB | 30 days | $23 | $2.30 |
| aloSIM | 5GB | 30 days | $16 | $3.20 |
*$29 is GOAN's group price (2+ eSIMs). Single eSIM is $39.
That per-GB column tells the real story. GOAN's 20GB for $29 works out to $1.45/GB. That's roughly half the cost of Airalo and aloSIM. And from personal experience, 20GB is genuinely enough for two weeks of maps, messaging, social media, and the occasional video call home.
About Holafly's "unlimited" plan. I need to be honest here. A friend used it in Barcelona last summer and got throttled to basically unusable speeds after about 1.5GB in a single day. Multiple people in travel forums report the same thing. For $44, that felt like a gamble she wished she hadn't taken.
Country Coverage
This matters more than people think. Not every "Europe plan" actually covers all of Europe:
| Provider | European Countries | Total Countries |
|---|---|---|
| GOAN | 40+ | 105+ |
| Airalo | 30+ (varies by plan) | 190+ |
| Holafly | 30+ | 60+ |
| Nomad | 30+ | 100+ |
| aloSIM | 25+ | 80+ |
All five cover the obvious destinations: France, Italy, Spain, Germany, UK, Portugal. Where it gets interesting is the smaller countries. If you're doing the Balkans (Montenegro, Albania, North Macedonia) or heading to places like Iceland or the Baltics, check the coverage map before you buy.
GOAN and Airalo both cover the widest range. Airalo technically lists more countries, but many are sold as individual country plans rather than a single regional profile. With GOAN, one plan covers 105+ countries on a single profile.
The Phone Number Thing Nobody Talks About
This is the part that frustrates me about most eSIM reviews. They compare data and price but ignore whether you actually get a phone number.
Most travel eSIMs are data-only. No phone number. No calls. No SMS. You rely entirely on WhatsApp and iMessage.
That works until it doesn't.
I learned this in Rome when I needed to call a restaurant to push back a reservation. Data-only eSIM. No phone number. I had to find a payphone. In 2025. In Rome. It was not a great moment.
| Provider | Real Phone Number? |
|---|---|
| GOAN | Yes |
| Airalo | No (data only) |
| Holafly | No (data only) |
| Nomad | No (data only) |
| aloSIM | No (data only) |
GOAN is the only major provider that gives you a real phone number with every plan. You can make and receive calls and texts without VoIP workarounds. This alone was the reason I switched.
If you're wondering how eSIMs work alongside your existing number, I wrote a full explainer on what eSIMs are and how they work. Short version: your home SIM stays in the phone, and the eSIM runs alongside it.
Setup Experience
Every provider uses QR code activation. The process is basically identical everywhere:
- Buy plan, get QR code via email
- Scan QR with phone camera
- Enable eSIM in settings
- Connected
All five got me online in under 2 minutes. No real difference in setup speed.
Where they differ: Holafly makes you download their app. Airalo has an app but doesn't require it. GOAN, Nomad, and aloSIM are fully app-free. Scan and go.
If you've never set up an eSIM before, GOAN has a step-by-step visual guide that walks you through it on iPhone and Android. I sent it to my mum before her trip to Portugal and she managed it on her own, which is saying something.
Group Travel (Where It Gets Interesting)
I usually travel with at least one other person. Sometimes it's a group of 4-6. This is where pricing changes dramatically.
Say you're a group of 4 heading to Europe for 2 weeks:
| Provider | Plan | Per Person | Group Total |
|---|---|---|---|
| GOAN | 20GB each | $29 | $116 |
| Airalo | 10GB each | $26 | $104 |
| Holafly | "Unlimited" each | $44 | $176 |
| Nomad | 10GB each | $23 | $92 |
Nomad looks cheapest on paper. But that's 10GB vs GOAN's 20GB. Per gigabyte, GOAN wins. And you all get phone numbers, which means you can actually call each other without relying on Wi-Fi.
I've been on group trips where half the crew had data-only SIMs and the other half had nothing. Coordinating anything was a nightmare. Having everyone on the same plan with real numbers makes everything smoother.
My Personal Pick
Best overall: GOAN. 20GB for $29 (group pricing), 105+ countries, real phone number, no app required. It's what I use and what I recommend to anyone who asks me in hostels.
Best if you need a hyper-specific country: Airalo. If you're going somewhere genuinely off the grid and need a plan tailored to one country, Airalo's marketplace will probably have it. Just expect to pay more per gig.
Fine for solo light users: Nomad. 10GB for $23 is decent if you're a solo traveller who mainly uses maps and messaging. But you'll burn through it fast if you're posting stories or video calling.
Skip Holafly unless you barely use data and just want peace of mind. The "unlimited" claim comes with asterisks, and at $44 for 15 days, it's the priciest option.
Ready to Pick?
If you're heading to Europe with friends, a partner, or family, GOAN is built for exactly that. Group pricing, real phone numbers, 105+ countries on one plan.
