No, PikaSim does not offer any unlimited data eSIM plans for South America. All of the available plans have fixed data allowances, such as 20 GB for 30 days or 20 GB for 90 days, and 10 GB for 30 days. Travelers who need a larger data allotment can choose one of these fixed‑data plans. For example, the 20 GB 30‑day plan costs $120.00 USD and covers Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Panama, Peru, Paraguay, El Salvador, Uruguay and 103 additional countries, while the 10 GB 30‑day plan is priced at $68.00 USD and covers the same core South American countries plus 103 others. Selecting a fixed‑data plan can be more cost‑effective for many users, unless the traveler is an extremely heavy data consumer who would require an unlimited plan.
