The plan sold as South America is really a Latin America plan. Its 20 destinations include Puerto Rico, Guadeloupe, Martinique, Guatemala, Costa Rica, Panama and Nicaragua, and only 9 of the 20 are South American countries. Venezuela, Guyana, Suriname and French Guiana are not in it at all.
Prices run from $0.92/GB in Saint Martin to $5.93/GB in Bolivia, and only 8 of the 20 carry a 5G partner, the second weakest ratio of any region here. This page compares four providers on published catalogue numbers and names where each one loses.
Which providers work best in South America?
| Rank | Provider | Best For | Why |
|---|---|---|---|
| #1 | HelloRoam | Lowest rates in 17 of 20 Latin American destinations | HelloRoam rates 4.9/5, the highest overall score on this page, and its plan covers 20 destinations on 6 partner operators. Saint Martin runs $0.92/GB and Brazil $1.78/GB. Top-up works on 1,124 of its 1,129 plans, hotspot is on all 1,129, and an unactivated eSIM stays refundable for 180 days against 14 at Airalo. |
| #2 | Airalo | Cheaper 5 GB in Brazil, Colombia and Bolivia | Airalo rates 4.5/5 across 200 destinations, 15 more than HelloRoam, and it genuinely wins 3 markets on the 5 GB size: $14 for 5 GB in Brazil, $16 for 5 GB in Colombia and $29 for 5 GB in Bolivia. It also sells Venezuela, which is absent from the 185-destination catalogue entirely. |
| #3 | Holafly | Unlimited data on long Andean stays | Holafly rates 4.2/5 across 160 destinations and sells unlimited data only, from $19 for 5 days, dropping to $6.97 for 5 days in Argentina, Peru, Uruguay, Paraguay and Ecuador. On a country where 5 GB costs $24.99, that is a serious option. There is no small tier and hotspot is not enabled on every plan. |
| #4 | Nomad eSIM | Single short stays | Nomad rates 4.2/5 across 120 destinations, the smallest catalogue on this page. Its entry tier is 1 GB at $3.00 and its 10 GB tier works out at $2.00/GB, against $0.80/GB at the top of this table. For one week in one country it is workable, and over a month it costs far more. |
Countries in South America
What the 20-destination South America plan covers
The full list is Puerto Rico, El Salvador, Martinique, Uruguay, Honduras, Chile, Paraguay, Guadeloupe, Saint Barthelemy, Colombia, Bolivia, Guatemala, Costa Rica, Brazil, Argentina, Panama, Peru, Saint Martin, Nicaragua and Ecuador. Read it twice: 11 of those 20 are Central American or Caribbean, not South American.
The 9 South American countries inside it are Uruguay, Chile, Paraguay, Colombia, Bolivia, Brazil, Argentina, Peru and Ecuador. That leaves Venezuela, Guyana, Suriname and French Guiana outside. Venezuela is absent from the whole 185-destination catalogue, not just from this plan, so a Caracas leg needs Airalo or a local SIM.
The upside of the wide definition is real. A Costa Rica, Panama and Colombia route runs on one profile because all 3 sit inside this plan, even though only one of them is in South America. A Guatemala and Puerto Rico pairing works the same way.
Every plan compared here is data only. There is no voice and no SMS on any of the 1,129 plans in the catalogue, so a local phone number still means a physical SIM bought on arrival.
Coverage and 5G across Latin America
Only 8 of the 20 destinations carry a 5G partner: Puerto Rico, Martinique, Chile, Guadeloupe, Saint Barthelemy, Colombia, Brazil and Saint Martin. The other 12, including Argentina, Peru, Ecuador, Bolivia, Uruguay and Paraguay, are 4G purchases. That is the second weakest 5G ratio of any region on this site, ahead only of Africa at 7 in 29.
Six partner operators cover the whole plan, the thinnest bench anywhere in this comparison. Claro alone carries 9 of the 20 markets, Orange carries the 4 French Caribbean territories, and Movistar carries 3. Brazil, Chile and Bolivia each have a single dedicated partner in TIM, WOM and Tigo.
One operator per country means no fallback network. In Argentina that shows up on Ruta 40, where Movistar coverage runs out for long stretches. In Chile it shows up on the Carretera Austral.
In Peru it shows up the moment you leave the Sacred Valley road.
Patagonia deserves a blunt statement. Torres del Paine has no service inside the park boundary from any carrier, and the Inca Trail has none either. Download offline maps in the last town, save your bookings locally, and treat any signal in a national park as luck rather than as a plan.
South America eSIM prices against local SIMs
Local prepaid SIMs in Brazil, Argentina and Chile are cheaper per gigabyte than any eSIM on this page. That is true, and it stays true. The trade is a store visit, an ID check and a SIM swap in each country you enter.
On the eSIM side, HelloRoam prices Brazil at $1.78/GB with 5 GB at $14.98, Argentina at $2.10/GB with 5 GB at $14.99 and Chile at $2.15/GB with 5 GB at $14.98. Peru is $2.35/GB with 5 GB at $16.
The rivals are close and sometimes ahead. Saily sells 5 GB in Brazil for $13.99, which is the lowest Brazil figure anywhere on this page, and 5 GB in Argentina for $16.99. Airalo sells 5 GB in Brazil for $14 and 5 GB in Colombia for $16, and both of those beat the numbers above.
In the other direction Airalo asks $30 for 5 GB in Uruguay against $28.49 and $30 for 5 GB in Paraguay against $26.99.
The threshold that matters is the border count. For one country over two weeks, a local SIM wins on price. For the classic Buenos Aires, Santiago and Lima circuit, one regional profile covers all 3 with no counter queues, and the per-gigabyte premium buys back several hours.
Argentina adds a currency wrinkle. Local SIM prices in dollars move with the exchange rate, while every figure on this page is fixed in dollars at purchase.
Frequently asked questions
What is the cheapest eSIM for South America at 5 GB?
Saily sells 5 GB in Brazil for $13.99, the lowest single figure on this page. Airalo asks $14 for the same size and HelloRoam $14.98. Across the wider plan HelloRoam prices Saint Martin at $0.92/GB and Brazil at $1.78/GB, so the ranking flips as soon as you buy more than 5 GB.
Does eSIM work in the Amazon rainforest?
Only in the river towns with towers, such as Iquitos, Leticia and Manaus. Once you are on the water or at a jungle lodge there is no signal from any provider at any price. Peru runs on Claro at $2.35/GB and Brazil on TIM at $1.78/GB, and neither reaches the interior. Download everything first.
Do I need a different eSIM for Brazil and Argentina?
No. Both sit inside the same 20-destination regional plan, alongside Chile, Peru, Colombia, Ecuador, Bolivia, Uruguay and Paraguay. One profile covers the border crossing. Brazil is $1.78/GB and Argentina $2.10/GB, and a country plan is cheaper if you are visiting only 1 of the 2.
Which South American countries are missing from the plan?
Venezuela, Guyana, Suriname and French Guiana. Venezuela is absent from the whole 185-destination catalogue, not just from this regional plan, so it needs Airalo or a local SIM. The other 9 South American countries are all covered, alongside 11 Central American and Caribbean destinations.
Is 5G available on eSIMs in South America?
In 8 of the 20 destinations: Puerto Rico, Martinique, Chile, Guadeloupe, Saint Barthelemy, Colombia, Brazil and Saint Martin. The other 12 are 4G, including Argentina, Peru, Ecuador, Bolivia, Uruguay and Paraguay. Across all 185 destinations in the catalogue 5G runs in 93, so this region sits below the global rate.
How much data do I need for a 2-week South America trip?
Five gigabytes covers maps, messaging and light browsing for 14 days. In Brazil that is $14.98 and in Argentina $14.99. Ride-hailing apps and photo uploads push you toward 10 GB, at $25.63 in Brazil and $26.99 in Argentina. Holafly's unlimited product at $6.97 for 5 days suits anyone streaming daily.
Do eSIM plans work in Venezuela?
Not from HelloRoam. Venezuela has no plan in the 185-destination catalogue at all. Airalo does sell it, at $34 for 5 GB, which is the most expensive figure of any destination on this page. Check coverage before you commit to a route that crosses the border from Colombia or Brazil.
Is eSIM coverage reliable in the Galapagos Islands?
Partly. Ecuador runs on Movistar on 4G at $2.63/GB, with 5 GB at $24.99, and that covers Puerto Ayora on Santa Cruz and Puerto Baquerizo Moreno on San Cristobal. Remote islands and dive sites inside the national park have no service. Download navigation and bookings before any inter-island boat.
Which provider is best for a Colombia trip at 5 GB?
Airalo, at $16 for 5 GB in Colombia against $20.16. Colombia is one of only 3 markets in this plan where the rival is the better 5 GB buy, alongside Brazil and Bolivia. Movistar carries Colombia on 5G either way, so the network is identical and only the price differs.
