ETravelSim does not provide an unlimited‑data eSIM for South America. They offer fixed‑data solutions instead. For example, their Latin America eSIM supplies 20GB of data for 30 days and covers Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, Peru, Uruguay and two additional countries. Another choice is the Seafarer eSIM, which also delivers 20GB for 30 days and covers the same core Southern American markets plus Paraguay, Bolivia and an extra 112 countries. Fixed‑data plans can be more cost‑effective unless you anticipate very heavy data usage.
