South America eSIM: what it costs and where it stops working
South America is cheap for mobile data and geographically brutal for mobile networks. Those two things coexist, and the itinerary you've planned determines which one you notice.
South America plans currently start from $1.26 per GB.
How South America works for mobile data
Prices are genuinely low. Brazil sits around $1.26 per gigabyte, Argentina and Chile around $1.70, Peru around $1.80. These are European-level prices in a continent where roaming used to be ruinous, and the reason is straightforward: huge domestic markets with real competition between Claro, Movistar, Vivo and Entel.
Coverage in cities is correspondingly good. São Paulo, Buenos Aires, Santiago, Bogotá and Lima all have dense 4G and increasing 5G. If your trip is urban, this region will feel unremarkable in the best way.
Then there's the geography. The Andes create shadow zones that no amount of investment fixes — signal follows the valleys and the roads, and vanishes on the passes. The Amazon basin is largely unserved outside the river towns. Patagonia has long stretches, particularly on Ruta 40 and the Carretera Austral, with nothing at all. The Atacama and the Bolivian altiplano are similar.
The practical version: coverage tracks population and roads with unusual precision here. If you can see a settlement, you probably have signal. If you're between them, assume you don't.
South America countries and prices
Prices are live floor prices per gigabyte from our current catalogue and change as wholesale rates move.
Single-country or regional?
One country, one to three weeks
Buy the country plan. Brazil, Argentina and Peru are individually cheap enough that a regional plan is hard to justify.
The classic Andean loop
Peru–Bolivia–Chile, or Peru–Ecuador–Colombia, involves real land border crossings at places with limited connectivity. A regional plan is worth the premium here.
Brazil plus Argentina
Usually a flight, and usually two distinct legs. Two country plans beat one regional plan on price.
Long-term travel
If you're moving for two months or more, buy per country as you go. You'll pay less overall and you avoid committing to a coverage list you'll drift out of.
How much data to buy
Two weeks of typical travel use runs about 5 GB. South America skews higher than average on ride-hailing and translation apps and lower on streaming, since long-distance buses and hostels tend to have Wi-Fi. Budget more if you're relying on data for remote work from Medellín or Buenos Aires — both are serious nomad hubs and you'll use it like home broadband.

How much does eSIM data cost in South America?
Brazil is cheapest at around $1.26 per gigabyte, with Argentina, Chile and Peru between $1.70 and $1.85. Bolivia is the outlier at roughly $5 per gigabyte because of its smaller, less competitive market.
Will my eSIM work on the Inca Trail or at Machu Picchu?
Machu Picchu itself and Aguas Calientes have usable coverage. The Inca Trail has intermittent signal at higher camps and none in the valleys. Ollantaytambo and the Sacred Valley towns are well covered.
Does mobile data work in Patagonia?
In the towns — El Calafate, El Chaltén, Puerto Natales, Bariloche — yes. Between them, frequently not. Ruta 40 and the Carretera Austral have long unserved stretches, so download offline maps before you set off.
Do I need a separate eSIM for the Galápagos?
An Ecuador plan covers the Galápagos in principle, but actual coverage on the islands is limited to Puerto Ayora, Puerto Baquerizo Moreno and a few other settlements. Boats and outer islands have nothing. Don't plan on being reachable.
Is one South America eSIM enough for a multi-country trip?
It can be, but check the coverage list carefully — regional plans in this continent vary a lot in which countries they include, and Bolivia and Paraguay are frequently missing. If your route is only two countries, two single-country plans are usually cheaper.
Which network do travel eSIMs use in Brazil?
Usually Claro or Vivo, both of which have national footprints and 5G in the major cities. Coverage differences between them matter mainly in the Amazon and the rural northeast.
