How We Tested
We evaluated each eSIM across real trips in Europe in early 2026, testing in cities including London, Paris, Barcelona, Rome, Prague, and Warsaw, as well as rural routes through the French Alps and the Algarve coast. For each provider, we measured:
- Download and upload speeds (using fast.com and Speedtest)
- Signal consistency on trains and in underground metro stations
- Activation time from QR scan to live connection
- App usability and clarity of plan details
- Customer support response time (live chat and email)
We used each eSIM as the primary data connection for at least 5 days before scoring.

- Plans up to 90 days, the longest we found across all providers
- Works in non-EU countries like the UK, Iceland, and Turkey

eSIM Setup: Step-by-Step
- Check compatibility. Your phone must be eSIM-capable and carrier-unlocked. iPhones from XS/XR onward support eSIM, as do most flagship Android phones (Pixel, Samsung Galaxy S series) from 2019 onward.
- Buy before you fly. Purchase your plan online and receive a QR code by email. You’ll need Wi-Fi to activate, so doing it at home is easiest.
- Install the eSIM. On iPhone: Settings → Cellular → Add Cellular Plan → scan QR code. On Android: Settings → Network → SIM cards → Add eSIM. Follow on-screen prompts.
- Label it. Name the plan “Europe Data” to avoid confusion with your home SIM.
- Set data roaming on. Your eSIM won’t work until data roaming is enabled for that line in your phone settings.
- Activate on arrival. Most providers let you install in advance and activate only when you land — saving your plan days for your actual trip.
Frequently Asked Questions
How many GB do I need for a week in Europe?
For light use (maps, messaging, social media): 2–3 GB per week. For moderate use (video calls, music streaming, photo uploads): 5–7 GB per week. For heavy use (streaming video, hotspot sharing, large uploads): 10 GB+ per week. When in doubt, go one tier up — you won’t get a refund for unused data.
Do Europe eSIMs work in the UK after Brexit?
Some do, some don’t. The UK is no longer part of EU roaming agreements, so always verify the country list before buying. Holafly, aloSIM, and Yesim explicitly include the UK. Airalo’s Eurolink plan covers the UK as well. Orange Holiday does not.
Can I use an eSIM and keep my regular number active at the same time?
Yes. This is one of the biggest advantages of eSIM. Your physical SIM (home number) stays active for calls and texts. The eSIM handles data. Your phone switches between them automatically.
Is eSIM safe to use on public Wi-Fi to activate?
Yes. Activating an eSIM requires scanning a one-time QR code over any internet connection. There’s no personal financial data transmitted during activation — you’ve already paid before receiving the QR code.
What happens if I run out of data mid-trip?
All providers except Holafly offer data top-ups. Airalo, Saily, and Yesim have the most seamless in-app top-up experiences. With Holafly, you’d need to buy a new plan — so size up if you’re unsure.
Are cheap eSIMs from unknown providers safe?
Stick to providers with substantial verified reviews on Trustpilot or the App Store. The providers in this list are all established, with real customer feedback. Be cautious of providers with fewer than a few thousand reviews and no published network partner information.
