eSIMatrix does not currently provide unlimited data eSIM plans for South America. The available options are fixed data plans, such as the South America 20GB plans that range from 5, 10, 15, or 30 days in validity and the South America 10GB plan for 5 days. These plans cover Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Peru, Paraguay, El Salvador, Uruguay, Venezuela and three additional countries. For most travelers, a fixed data plan may be more costโeffective, while those who consume very large amounts of data may need to explore alternatives that offer unlimited data.
