Supera link does not provide any unlimited data eSIM plans for South America. All of the South America‑supported plans are fixed‑data packages with a daily allowance of 5 GB. A common example is the Global 109 Countries plan that offers 5 GB per day for validity windows of 7 days, 10 days, 15 days, 20 days or 30 days, with prices ranging from $42.01 USD to $175.68 USD.
Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data user who needs unlimited usage for a long period. The fixed plans still provide high‑speed connectivity across Argentina, Brazil, Chile, Colombia, Costa Rica, Guatemala, Panama, Peru, Uruguay and many other countries.
