Airalo (9.3/10) has the widest coverage in South America, covering all 12 countries in the region. It routes through Claro in Brazil, Argentina, and Colombia, Movistar in Peru and Chile, and Entel in Bolivia on 4G LTE. The 5 GB plan suits a 10-day trip across 2 to 3 countries. Multi-country coverage is the decisive factor: the Gringo Trail from Colombia to Argentina crosses 5 borders. Budget travelers saving money on single-country trips should check Nomad’s per-country rates.
South America backpacker trips cross multiple borders. Airalo covers all 12 countries from a single account, which removes the friction of managing separate plans at each crossing.
Airalo routes through Claro in Brazil, Argentina, and Colombia, Movistar in Peru and Chile, and Entel in Bolivia. These are each country’s leading carriers in terms of geographic coverage. The Americas regional bundle option covers the entire continent on one eSIM profile, which suits travelers doing the full Gringo Trail circuit or combining Atlantic and Pacific coast destinations.
Airalo scored 5.0 out of 5 on coverage and 4.9 out of 5 on app quality in our testing. The Airmoney cashback rewards of 5 to 10% benefit travelers buying multiple country plans across a long South America itinerary. Accumulated cashback reduces effective cost on later plans in the trip.
Airalo’s weakness for South America is per-GB pricing. At $4.50 per GB globally, it costs more than Nomad in Brazil, Argentina, and Colombia where Nomad’s per-country plans offer lower rates. For any trip that stays within 1 or 2 countries, run the numbers on Nomad before defaulting to Airalo.

For the full Gringo Trail from Cartagena to Buenos Aires crossing Colombia, Ecuador, Peru, Bolivia, and Argentina, buy Airalo’s Americas regional bundle. Per-country plans work better for extended single-destination stays. A 10-day Colombia trip does better with a dedicated Colombia plan. A 30-day circuit hitting 5 countries is where the regional bundle earns its convenience premium over 5 separate plan purchases.
Nomad scores 8/10 and earns the runner-up position for South America on pricing. It covers 9 of the 12 South American countries, missing Bolivia, Paraguay, and Guyana, but covers all major tourist destinations with competitive per-GB rates.
Nomad routes through Claro in Brazil and Colombia, and local carriers in Argentina, Peru, and Chile. Per-GB rates are lower than Airalo in these markets. For a single-country trip to Brazil, Argentina, or Colombia where budget matters most, Nomad costs meaningfully less per gigabyte.
Nomad’s weakness for South America is coverage breadth. The 3-country gap including Bolivia, Paraguay, and Guyana is not trivial for travelers doing the full circuit. Machu Picchu, the Galapagos, and Patagonia trips often cross into these territories. Any itinerary that touches Bolivia requires switching to Airalo for that leg.
Choose Nomad for single-country trips of 7 or more days in Brazil, Argentina, or Colombia where the per-GB savings compound. A 14-day Brazil trip at 1.5 GB per day needs 21 GB total. At Airalo’s global rate versus Nomad’s Brazil rate, the savings can reach $20 to $40 on a large data plan.

Holafly covers 8 South American countries with unlimited daily data at $2.99 per day. Strong options exist for Brazil, Argentina, Colombia, Peru, Chile, and Ecuador. It misses Bolivia, Paraguay, and Guyana.
Digital nomads working from Medellin, Buenos Aires, Sao Paulo, or Lima use the most data of any South American traveler profile. Daily video calls, heavy media consumption, and hotspot tethering for laptops can push usage to 5 to 10 GB per day, far above what any fixed-data plan efficiently covers. Holafly unlimited removes the calculation.
A 30-day Holafly plan costs $54.99 in major South American markets. Compare that to buying 30 GB of Airalo fixed data in the same markets. For any traveler using over 1.8 GB per day on average, Holafly unlimited costs less per gigabyte consumed.

South America has excellent connectivity in its major urban centers and serious coverage gaps everywhere else. Understanding this split before travel prevents unpleasant surprises.
Sao Paulo and Rio de Janeiro connect through Claro and Vivo at 30 to 60 Mbps average download speeds. Buenos Aires delivers 20 to 50 Mbps on Claro and Personal networks. Bogota connects at 20 to 40 Mbps. Lima runs 15 to 35 Mbps on Claro and Movistar.
These five cities anchor most South America itineraries. Test your eSIM in the arrival city before heading into remoter areas. Download offline maps and content while you have strong 4G coverage.
Altitude alone does not affect eSIM coverage. What matters is cell tower density. High-altitude cities like Cusco at 3,400m and La Paz at 3,640m have strong 4G because they have towers. The Andean altiplano between towns, the Bolivian salt flats, and the Atacama Desert have almost no towers regardless of altitude.
In the Andes, plan for connectivity blackouts during transit between towns. The bus ride from Cusco to Puno covers significant distances with no coverage. The route from La Paz to Uyuni crosses the altiplano with intermittent signal at best.
Brazil requires CPF (tax identification) registration for local SIMs. Argentina requires passport registration at kiosks. Peru enforces IMEI registration for devices staying over 30 days. eSIM providers handle registration requirements automatically when you purchase, which removes the paperwork burden entirely. This is one of the strongest advantages of eSIM over local SIM cards for South American travel.
