Best eSIM for Europe (2026)
Checked 2026-06.
Checked 2026-06: for most travelers crossing Europe, a regional travel eSIM beats carrier roaming on price and convenience — install it before you fly, land connected, and pay a fraction of a daily roaming pass. Our pick is Airalo's Eurolink plan, which covers ~40+ countries on one eSIM with 5G where available.
Airalo's "Eurolink" regional plan spans roughly 40+ European countries (including non-EU stops like Switzerland, Norway, the UK and Turkey) on one eSIM, with widely available 5G — the broadest single-eSIM footprint if your trip crosses borders. For a single country, Saily can be a few dollars cheaper, so compare both before you buy.

| Option | Data | Validity | Price | Notes |
|---|---|---|---|---|
| Airalo (Eurolink) | 1 GB - 100 GB tiers (+ unlimited) | 7-180 days (tier-dependent) | from ~$4 (1 GB) up; ~$15-50 mid-tiers | ~42 countries incl. UK, Switzerland, Norway, Turkey. 5G where available. Data-only. Our pick for multi-country trips. Prices vary — check live. |
| Saily (Europe) | 1 GB - 50 GB tiers (+ unlimited) | 7-90 days (tier-dependent) | from ~$4.99 (1 GB); ~$12-36 mid-tiers | ~34-35 countries. Data-only. Often a touch cheaper for single-country / smaller plans. Good runner-up. Prices vary — check live. |
| Carrier roaming (daily pass) | Uses your home plan's data (often throttled) | Per-day, auto-renews on use | ~$10-15 per day | Keeps your number for calls/SMS but adds up fast: a 1-2 week trip runs ~$84-210. Easiest, most expensive. Pay-per-use without a pass is ruinous. |
| Local SIM (in-country) | Large local allowances | ~30 days typical | ~€10-25 | Cheapest per-GB and gives a local number, but you must buy/swap on arrival and it usually covers one country, not all of Europe. Less practical for multi-stop trips. |
Coverage and networks: Both Airalo and Saily are data-only eSIMs that roam onto established local mobile networks rather than running their own — so in practice you get the same towers a local SIM would. Airalo's main Europe plan, "Eurolink," covers around 42 countries (the EU plus Switzerland, Norway, Iceland, the UK, the Balkans and Turkey), while its tighter "EUconnect" plan sticks to ~28 EU states. Saily's Europe regional plan covers roughly 34-35 countries. If your itinerary is EU-only, both are fine; if you'll dip into non-EU stops, Airalo's wider Eurolink list is the safer single-eSIM choice. Speeds reach 5G where the local carrier supports it.
How to activate: An eSIM only works on an eSIM-capable, carrier-unlocked phone (essentially every iPhone since the XS and most recent Android flagships — check Settings for an "Add eSIM" option). Buy and install the eSIM at home over Wi-Fi a day or two before you fly: you scan a QR code or tap an in-app install, and the profile sits dormant until you arrive. On landing, toggle the travel eSIM on for data and turn data roaming OFF on your home line so it doesn't bill you. Your physical/primary SIM stays in the phone, so you keep your home number for calls and texts over Wi-Fi or your normal line.
Data sizing: Light use — maps, messaging, boarding passes, the odd lookup — runs roughly 300-500 MB per day, so 3-5 GB comfortably covers a one-week trip. If you stream video, tether a laptop, or post lots of photos/stories, budget closer to 1-2 GB per day and size up to 10-20 GB, or look at an "unlimited" tier (note these throttle after a daily high-speed cap — about 3 GB/day on Airalo, 5 GB/day on Saily — then slow to ~1 Mbps). When unsure, buy a mid-size plan and top up in-app rather than overbuying.
Validity and gotchas: Validity is a countdown that starts when the eSIM first connects to a network, not when you buy it — so installing early is safe, but don't activate until you land. Europe-specific things to watch: (1) the UK and Switzerland are NOT in the EU, so confirm they're on your plan's country list (Eurolink includes them, EUconnect does not); (2) these are data-only — no local phone number for SMS two-factor codes, so set up app-based or Wi-Fi authentication before you go; (3) coverage in remote rural areas and on some trains/ferries depends on the underlying carrier, same as any SIM. Always check device compatibility on the provider's page before buying.

FAQ
Does an eSIM work in Europe?
Yes. Travel eSIMs from Airalo and Saily connect to established local networks across the EU and most of wider Europe, with 5G where the local carrier supports it. You just need an eSIM-capable, unlocked phone — most iPhones since the XS and recent Android flagships qualify.
How much data do I need for a trip to Europe?
For maps, messaging and light browsing, plan on roughly 300-500 MB per day — about 3-5 GB for a week. If you stream video or tether a laptop, budget 1-2 GB per day and choose 10-20 GB or an unlimited tier. You can usually top up in-app if you run low, so there's no need to overbuy upfront.
Can I keep my phone number with a travel eSIM?
Yes. The travel eSIM handles data only and runs alongside your existing SIM, so your home number stays active for calls and texts (use Wi-Fi or your normal line). Because the eSIM has no number of its own, set up app-based or email two-factor authentication before you travel rather than relying on SMS codes.
Airalo or Saily for Europe — which is better?
For a trip crossing several countries, Airalo's Eurolink covers more of the continent (~42 countries, including non-EU stops like the UK, Switzerland and Norway) on one eSIM, which is why it's our pick. Saily is often a little cheaper for a single country or smaller plans, so it's worth comparing both live prices before you buy.
