South America is a continent of extremes — from the tech-forward cities of Brazil, Argentina, and Chile to the remote highlands of Bolivia and Peru. Mobile coverage is strong in urban areas but drops quickly in the Andes, Amazon, and Patagonia. Choosing an eSIM for South America means matching your itinerary to provider coverage.
Coverage by country
Strong coverage: Brazil (Claro, Vivo, TIM — excellent in cities, solid along highways), Argentina (good in Buenos Aires, Mendoza, Patagonia towns), Chile (strong along the main north-south corridor), Colombia (good in Bogotá, Medellín, Cartagena). Moderate: Peru (Lima and Cusco are good, Machu Picchu area and Amazon lodges have limited signal), Ecuador, Uruguay. Limited: Bolivia, Paraguay, Guyana — check provider coverage carefully.

Data tips for South America
Ride-hailing is essential. Uber, DiDi, and Cabify are the safest transport options in most South American cities. They require data. Spanish/Portuguese translation. Google Translate with downloaded language packs works offline for text — but live camera translation needs data. Machu Picchu and Inca Trail. There is no coverage on the Inca Trail. Download all maps and information before starting. Cusco and Aguas Calientes (base town) have decent coverage. Patagonia. Coverage exists in El Calafate and El Chaltén towns but drops on trails and glaciers. Amazon lodges. Most have no cell coverage — expect to be offline. Budget 3–5 GB per 2 weeks. South America trips involve more offline time than European travel.
