One eSIM for 41 European Countries (2026) — And When It Beats Buying Separately
One eSIM for 41 European Countries — And the Honest Math on When It Beats Buying Separately
Updated August 2026 · Prices in USD, verified at checkout · Country list from our supplier’s live catalogue
A regional eSIM sounds obviously right for a multi-country trip and is often the wrong buy. It costs roughly three times as much per gigabyte as a single-country plan, so it only pays off past a certain number of borders — and that number is lower than you think, but not as low as the marketing suggests. Here is the arithmetic, the full country list, and the four places it genuinely has no competition.
41 countries · One profile · QR by emailSee the Europe eSIM — 10 GB for $26.90 →The break-even, calculated honestly
Our Europe plan gives you 10 GB for $26.90. Our single-country plans give you 10 GB for around $8.90 each. So on pure gigabytes, the single-country plans win by a wide margin — three of them cost $26.70 and give you 30 GB, not 10.
| Your trip | Buy separately | Europe plan | Better |
|---|---|---|---|
| One country | $8.90 (10 GB) | $26.90 (10 GB) | ✓ Separate — by a mile |
| Two countries | ~$17.80 (20 GB) | $26.90 (10 GB) | ✓ Separate, usually |
| Three countries | ~$26.70 (30 GB) | $26.90 (10 GB) | Separate on data, Europe on convenience |
| Five or more | ~$44+ (50 GB) | $26.90 (10 GB) | ✓ Europe — if 10 GB is enough |
| Route not decided yet | Impossible to plan | $26.90 | ✓ Europe |
So the honest rule: if you know your route and it is one or two countries, buy those countries. The Europe plan earns its price when you are crossing four or more borders, when your itinerary is genuinely undecided, when you are on a train pass and improvising — or when your route includes the countries in the next section.
The four places where nothing else comes close
European roaming rules cover the EU and EEA. This plan covers 41 countries, and the interesting ones are the six it includes that “roam like at home” does not:
• Switzerland — outside the EU and EEA, and the single most common European roaming bill shock.
• United Kingdom — no longer inside the EU rules, and several EU carriers now bill it separately.
• Turkey — outside entirely, and expensive on every home tariff.
• Ukraine, Serbia and North Macedonia — outside, and rarely included in any regional competitor’s list.
If your trip is Germany → Austria → Switzerland → Italy, your EU plan quietly stops being free in the middle of it. This one does not.
What the Europe plans cost
| Europe data package | Price | Cost per GB | Best for |
|---|---|---|---|
| 3 GB / 30 days | $12.90 | $4.30 | A short multi-city hop |
| 5 GB / 30 days | $17.90 | $3.58 | A week across a few borders |
| 10 GB / 30 days | $26.90 | $2.69 | Two to three weeks interrailing |
| 20 GB / 30 days | $42.90 | $2.13 | A month, or hotspot use |
| 50 GB / 180 days | $104.00 | $2.08 | A season of travel |
Every package runs for 30 days except the 50 GB, which runs 180 — useful if you are coming and going across a summer.

Where you get 5G and where you do not
37 of the 41 countries have at least one partner network with 5G. The four that are 4G only on this plan are Guernsey, the Isle of Man, Serbia and Ukraine. Four-G is entirely adequate for everything on this page — we list them because you should know before you buy, not after.
The honest caveat: your internet exits in the UK or Norway
This plan is home-routed like most travel eSIMs: your phone attaches to a local mast in whichever country you are standing in, but your traffic reaches the public internet through a gateway in the United Kingdom or Norway. Practically, that means websites see a British or Norwegian address wherever you are. Anything geo-locked to the country you are physically in — national broadcasters, some domestic banking portals — may object, and latency runs slightly higher than a local SIM. Browsing, maps, messaging, video calls and streaming are unaffected.
One incidental benefit of a regional plan: your apparent location stops jumping every time you cross a border, which some banking apps like considerably better than a new country every second day.
When a single-country plan is still the right answer
We would rather you bought the cheaper thing and came back than bought the expensive thing once. Buy single-country if: your trip is one or two countries; you are a heavy data user and need 20 GB or more (single-country gigabytes cost a third as much); or your destination is one where our local plan rides more networks than the regional one does.
Buy Europe if: you are crossing four or more borders; your route is improvised; you are on an Interrail or Eurail pass; or your trip includes Switzerland, the UK, Turkey, Ukraine, Serbia or North Macedonia alongside EU countries.
Getting online, step by step
1. Buy the plan; the QR code arrives by email within about a minute.
2. Scan it at home on Wi-Fi: Settings → Cellular/Mobile → Add eSIM.
3. Label it “Europe”, switch it off, and travel.
4. On arrival in your first country, turn the Europe line on with data roaming enabled for that line only.
5. Crossing a border changes nothing — the same profile re-registers on the next country’s network automatically. Keep your home SIM on for calls and SMS codes with its own data off.
Your QR code stays valid for 180 days before you install it, and the plan clock only starts when the eSIM first connects to a network in the destination country — not when you pay.
Questions travellers ask before buying
How many countries does it cover?
41, including six that European roaming rules do not cover: Switzerland, the United Kingdom, Turkey, Ukraine, Serbia and North Macedonia. The full list is above.
Is a Europe eSIM cheaper than buying per country?
Only past three or four borders. One 10 GB Europe plan costs $26.90; three separate 10 GB country plans cost about $26.70 and give you 30 GB. Buy separately for short, known routes; buy Europe for wide or improvised ones.
Do I need to do anything when I cross a border?
No. The same profile re-registers on the next country’s network automatically. There is nothing to switch, buy or reinstall.
Does it cover Switzerland and the UK?
Yes — both, plus Turkey, Ukraine, Serbia and North Macedonia. That is the strongest reason to choose it over relying on an EU home plan.
Do I get 5G everywhere?
37 of the 41 countries have a 5G partner network. Guernsey, the Isle of Man, Serbia and Ukraine are 4G on this plan.
Will national streaming services work?
Often not. Your data exits the internet in the UK or Norway, so services geo-locked to the country you are standing in see a foreign address.
Can I hotspot my laptop?
Yes — tethering is included at no extra charge, which is what makes the 20 GB tier worth considering for working trips.
When does my plan start?
On first connection to a network in any covered country, not at purchase. The unused QR code stays valid for 180 days.
