Data for Buenos Aires, Iguazú and Patagonia, installed before you fly. Argentina is on the Americas plan, so the same eSIM crosses to the Brazilian side of the falls, over the Andes into Chile and on the ferry to Uruguay. It will not settle who invented dulce de leche.
The Argentina plan covers Argentina only.
The same 10 GB in a package that keeps working past Argentina.
16 other countries share the package with Argentina. A few of them:
What's included, when it starts, and how to get connected.
Argentina is too big to cross by road on a first trip, so the classic fortnight joins a city, a waterfall and the southern ice with domestic flights. Keep a spare day in Patagonia for the weather. The line below is an illustration, not a map.
1Four days is the minimum. San Telmo’s antique fair and market, La Boca’s painted corrugated-iron houses, steak at a parrilla and a milonga after dark. Keep a day for Uruguay: the ferry crosses the River Plate to Colonia del Sacramento, and Uruguay is on the same plan.
2Fly north to Puerto Iguazú. Argentina has most of the roughly 275 falls and the walkway over the Devil’s Throat; Brazil has the panorama, so give each a day. Park entry for foreign visitors is ARS 60,000 (2026), and a second day within 72 hours is half price. Eleanor Roosevelt reportedly took one look and said ‘Poor Niagara’.
3Fly south to El Calafate on Lago Argentino. The Perito Moreno Glacier is 78 km away: a wall of ice 5 km wide and about 74 metres high, faced by walkways, with guided walks on the ice and chunks calving into the lake. Los Glaciares National Park charges foreign visitors ARS 50,000 a day (2026).
4Head 220 km north by road to Argentina’s national trekking capital, a village of about 3,000 people at the foot of Fitz Roy. The day hikes to Laguna de los Tres and Laguna Torre start in the village. The park’s El Chaltén entrance also charges ARS 50,000 in 2026, with half price for a second day.
How the plan fits this route
One package from the airport in Buenos Aires to the last trail: Argentina is on the Americas plan, and so are Brazil, Chile and Uruguay, which covers the Brazilian side of the falls, a ferry to Colonia and a detour to Torres del Paine. Coverage is strong in the cities and towns; on the Patagonian roads and trails it thins or disappears, on any network.
Guide: offline maps, done properly
The city’s central observatory has recorded snow only in 1918, 1928 and 2007. Then came El Eternauta, Netflix’s 2025 series of the 1957 comic, in which a deadly snowfall hits Buenos Aires one night. It was shot in more than 35 locations across the city, Avenida General Paz among them, and the crew made the footprints in its fake snow with kitchen salt. A second season is on the way.
It is a Buenos Aires trick the UK Foreign Office still describes: someone sprays mustard on you, a helpful passer-by offers to clean it off, and an accomplice leaves with your bag. Say no politely and move on. The same advice warns that phones get snatched on the street, so check the map in a café, not on the kerb.
Mate is shared: one gourd, one metal straw, one server — the cebador — who fills it, hands it round in turn and gets it back empty each time. Do not move the bombilla, and do not say thank you after your first round: gracias means you are done. Hold on to it too long and someone will remind you that it is not a microphone.
In 2003 Argentina tried to have dulce de leche declared part of its cultural heritage, and countries across South and Central America objected. Worse, customs records show manjar, as Chileans call it, being shipped into Argentina from Chile in 1693 and 1712, and an Argentine historian traces it to colonial Chile. None of this matters inside an alfajor.
The dinner shows are theatre. A milonga is where Buenos Aires dances, mostly to recordings from the 1930s to the 1950s. You do not ask out loud: an invitation is a look and a nod, the cabeceo, and saying yes commits you to the whole tanda of three or four songs. UNESCO listed tango for Argentina and Uruguay jointly in 2009.
Answers about data, coverage and setup for Argentina.
In the towns, yes; beyond them, often not. Coverage in Patagonia follows the towns, so El Calafate and El Chaltén are where your phone is happiest, while the trails to Fitz Roy and Laguna Torre and the long empty stretches of Ruta 40 can go silent for hours, on any SIM. Download maps, park tickets and bus times in town, and tell someone your hiking plan.
Yes. Uruguay, Chile and Brazil share the Americas plan with Argentina, so the ferry to Colonia or Montevideo, the road over to Torres del Paine and a day on the Brazilian side of the falls all run on the same package; the phone switches to a local network after each border. The paperwork is separate: US, Canadian and Australian passports have needed an e-visa for Brazil since April 2025. The Americas plan
Not the way you once did. Argentina lifted most of its currency controls in April 2025, and since then the ‘blue’ street rate and the official rate have stayed close: on 27 September 2026 the gap was a few per cent. A card or phone wallet now pays roughly what cash would. Keep some pesos for taxis, tips and small shops, and let the eSIM keep the banking app awake.
