ESIM GLOSSARY

Regional eSIM

A regional eSIM covers many countries in one area — like Europe or Asia — on a single plan, ideal for multi-country trips.

A regional eSIM bundles coverage for a group of neighboring countries — a "Europe 33 countries" or "Asia 12 countries" plan — so one profile works across borders without any action from you.

Regional plans usually cost slightly more per gigabyte than single-country plans but eliminate the hassle of buying and switching multiple eSIMs on one itinerary. They shine on trips crossing two or more borders.

Always check the covered-country list before buying: two "Europe" plans can cover different sets of countries, and popular add-ons like Switzerland, the Balkans, or Türkiye are not always included.
