SweetAsSIMAbout this eSIM
This one runs wider than South America alone, into Central America and the French Caribbean too. One SweetAsSIM eSIM covers all 20 countries on this bundle - Machu Picchu in Peru, Rio's coastline in Brazil, Costa Rica's rainforest, and the Panama Canal - 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.
