Europe is one of the clearest cases for buying a regional eSIM before departure. A single plan can cover a trip across France, Italy, Spain, Germany, the Netherlands, Portugal, and nearby countries without buying a new SIM at each border.
The main decision is whether you need a regional plan or a cheaper single-country plan. If your trip stays in one country, compare the country page first. If your itinerary crosses borders, start with a Europe regional plan and verify hotspot, fair-use, and validity rules.
