Western Europe eSIM Guides
All 59 Western Europe guides in one index: 16 countries, 15 cities, 12 airports and the local SIM card options for each, grouped so you can plan a whole route rather than one stop.
Western Europe is the one part of the world where the roaming rules do most of the work for you. An EU or EEA plan roams across the bloc at no extra cost, so a single eSIM bought for France generally behaves the same in Germany or Spain. The countries worth reading carefully are the ones sitting outside that arrangement. The UK left it after Brexit, Switzerland was never in it, and the microstates are a genuine trap: Andorra is not in the EU roaming area at all, and Gibraltar, Monaco and San Marino are each treated differently by different providers.

Planning a route across Western Europe?
Check whether a plan says EU or Europe. The second word often includes Switzerland, the UK and Turkey, and the first almost never does.
