Internet in South America: roaming, eSIM, local SIM and VPN explained
South America is a continent of extremes: the dense Amazon, the remote plains of Patagonia, and the high-altitude Andes. Here's how to stay online from country to country.
Roaming with your own plan
South America isn't covered by EU roaming rules. Traveling through multiple countries with a Dutch or Belgian plan means roaming charges can add up per country, check with your provider before you leave.
Regional eSIM for South America
A regional eSIM plan often covers several South American countries in a single profile, handy for long cross-border bus journeys like Chile to Argentina, without buying a new SIM each time.
Local SIM per country
Buying a local SIM at every border crossing takes time and is tedious. Activating a regional eSIM beforehand skips this hassle, especially on long treks through multiple countries.
Coverage across South America
In the Amazon and parts of Patagonia, coverage can disappear entirely, download offline maps and check with your accommodation in advance. At high altitude in the Andes (La Paz, Cusco), coverage in the cities is fine, but drops off quickly once you head into the mountains.
Do you need a VPN?
On long treks and bus journeys you're often relying on the one wifi hotspot in a small mountain town or along the route. Those limited, shared connections are exactly where security matters most, a VPN protects your data.
Practical tips
- In the Amazon and parts of Patagonia, coverage can disappear entirely, download offline maps in advance
- Long cross-border bus journeys (say, Chile to Argentina) can run for hours without signal, factor this into your planning
- At high altitude in the Andes (La Paz, Cusco) coverage in the cities is fine, but drops off quickly once you head into the mountains
- Check that your device supports eSIM before you leave
Our recommendation
For a multi-country trip, a regional eSIM is the simplest solution for South America. Sticking mainly to one country? A country-specific guide is often more precise, check our guide for Argentina or Brazil. Also read more about VPNs for South America.
