SweetAsSIMAbout this eSIM
Same run through Western Europe and the Nordics, with the Netherlands and Gibraltar added in. One SweetAsSIM eSIM covers all 33 countries on this bundle - Paris, Rome, Amsterdam's canals, and the Rock of Gibraltar - at full network speed the whole way, so you can cross into the next country without losing connection or paying roaming fees. Buy online, install before you fly, and it's ready the moment you land in the first country on your trip.

Almost certainly. Anything sold since 2019 is eSIM ready - dial *#06#, look for an EID, and you're good.

Most start the first moment your phone connects to a network at your destination, so it's fine to buy in January for a June trip and it'll sit there untouched until you land. A handful of plans instead start the moment you install the eSIM profile, so for those, install right before you fly rather than weeks ahead.
