eSIM for Europe: one plan across 34 countries
When a regional plan beats a single-country one, how it behaves at borders, and what to pick for a multi-country route.
A Prague–Vienna–Budapest route breaks the usual buying logic: three separate plans are expensive and fiddly, while roaming in two of the three will eat the trip budget. That is what regional plans are for — one profile that works across 34 European countries with nothing to switch at the border.
What happens at borders
There is one profile and many networks. When you cross a border, the phone finds a partner network in the new country by itself and keeps counting against the same data allowance. Nothing to toggle, no second profile to install.
In practice the handover takes anywhere from a few seconds to a couple of minutes — about as long as it takes locals driving between countries. If nothing appears after a couple of minutes, ten seconds of airplane mode usually fixes it.
When a regional plan wins
- Two or more countries on the route. Almost always cheaper than two separate plans.
- An open-ended trip, where "let's go to Bratislava for the day" is decided on the spot.
- Layovers. A long connection in another country stops being a problem.
When a single country is better
- One country for the whole trip. A country plan is usually cheaper than a regional one for the same allowance.
- A country outside the coverage list. The European plan covers 34 countries, not the entire continent; the list is always on the destination page.
How much to take
European trips mean maps, transit apps and looking places up — roughly 200–400 MB a day in normal use.
- A long weekend — 1–3 GB.
- Two weeks on the move — 5–10 GB.
In short
- One profile across 34 countries, nothing to switch at borders.
- Worth it from two countries onwards; for one country, buy that country.
- Check the coverage list — it is not the whole continent.
- The allowance is shared, not split per country.
