How regional plans work
A Europe eSIM connects to a partner network in each country it covers, so one plan works as you cross borders.
Check the list
Coverage lists differ. The UK, Switzerland, Turkey and the Balkans are the countries most often missing or limited. Check every country on your route before you buy.
When a single-country plan wins
If you spend most of the trip in one country, a single-country plan is often cheaper per GB and can include 5G.
