Horizon’s Latin America eSIM can cover Brazil, Argentina and Chile with one regional profile. Its exact ten-country set is Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, Peru, El Salvador and Uruguay.
Choose country plans for a trip that stays in one country and compare the regional option when the same itinerary crosses two or three included countries. Bolivia and Paraguay are outside the list. The decision comes from the written destinations and the current allowance, validity and checkout total, not from a continent-wide promise.
A continent on the map, a column of names in the catalogue
A plan is still a written list rather than a map. The new regional choice simply makes one useful list available for this route; it does not turn every neighbour into part of the product.
Uruguay, Peru, Colombia and Ecuador are included alongside Brazil, Argentina and Chile. Bolivia and Paraguay are excluded, even when a day trip makes the border feel minor. Read every stop by name before buying.
The list is the product, and it takes a minute to read
Before paying anybody, ours included:
- Write the route as a column of country names. Not regions, not the continent — the names, including the one you enter only for an afternoon.
- Open the plan itself rather than the shop's front page. A banner number is advertising; the list attached to a plan is a specification.
- Read your column against that list, one name at a time. A name is printed there or it is absent, and a neighbouring country is not an entry.
- Read the window as well as the places. A long, slow route can run out of days well before it runs out of gigabytes.
- Keep what you were shown. A page is easy to reopen from a hotel, awkward in a queue of cars.
Where our three country plans stop
The Brazil eSIM, Argentina eSIM and Chile eSIM remain the direct choices for a stay inside one country. They do not extend over a border simply because the next destination is nearby.
For a route across the three, compare those country products with the regional plan’s current allowance, validity and checkout total. Easter Island needs a live coverage check on the selected Chile or regional offer; treat that as a network-availability question, not an argument about political territory.
The single-plan route, and the condition attached
The honest one-profile answer is the Latin America eSIM. Its shared allowance follows the installed profile across Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, Peru, El Salvador and Uruguay where service is available. Bolivia and Paraguay are not included.
Compare the live regional product with the country options for the trip you are actually taking. A single-country stay may fit a country plan better; a route crossing Brazil, Argentina and Chile is the clear regional use case. Check the purchased validity against the full itinerary rather than assuming it resets at each border.
Buenos Aires, with a day in Uruguay
The fast ferry from Buenos Aires to Colonia makes Uruguay feel like a small side trip, but it is still another country. Uruguay is included in the Latin America plan, so the same profile can reconnect on land after arrival.
Do not turn that into a promise of service on the Río de la Plata. The destination list describes included countries, not maritime coverage between them. Save the ticket, meeting point and return details before boarding, and expect the regional data line to matter again after the phone reaches a supported network on land.
The falls, from whichever bank you booked
Iguazú puts Argentina, Brazil and Paraguay close together. The Latin America plan includes the Argentine and Brazilian sides on the same profile; Paraguay is excluded.
Use that profile after the phone connects on land in Argentina or Brazil. If Ciudad del Este is a real stop, prepare separate connectivity or offline details before crossing into Paraguay. A bridge does not add an excluded country to the allowance.
Two crossings that happen to be roads
Mendoza to Santiago is the classic one. Ruta 7 climbs through Uspallata and past Puente del Inca to Paso Los Libertadores, where the tunnel under the pass sits above three thousand metres, then drops through switchbacks toward Los Andes and the Chilean central valley. The bus takes most of a day, border control included. Half of it is spent in Argentina and half in Chile, a division the ticket never mentions.
Patagonia can still divide the nights differently from the arrival ticket, but it no longer requires choosing one country profile as the main purchase. Argentina and Chile are both included in the regional plan. Compare that one-profile option with separate country plans, then make sure its purchased validity covers the full road route and any weather-driven date change.
Tip: Both crossings depend on weather. A high pass or a southern park road can shut for a day, and the date you meant to change countries is the first thing a storm takes off the calendar. If the second country is one date in a fortnight, decide in advance what you will do when that date moves.
Quick answers
Does a Brazil country plan work on the Argentine side of the falls? No. A Brazil-only plan stops at Brazil, while the Latin America plan lists both countries.
Is there a South America plan? Horizon sells the ten-country Latin America eSIM. Read that exact list; it is not all of South America.
Country plans or one regional profile? Choose by route. A stay in one country points to its plan; a journey through Brazil, Argentina and Chile is built for the regional option.
What about Easter Island, Bolivia or Paraguay? Check Easter Island in the live coverage details of the selected offer. Bolivia and Paraguay are not in Horizon’s Latin America list.
Which one do I buy first? Compare the live regional and country options before departure. Match allowance and validity to the entire route, including the first country where the regional profile will connect.
Current allowances, validity and exact country coverage sit on the destination pages above and on the Latin America eSIM page. For longer trips at either end of the continent, use the Brazil buyer’s guide and the Argentina guide to estimate data before comparing the live options.
