eSIM Argentina

For the long legs, yes, and almost everyone does. Buenos Aires to Iguazú is roughly 1,300 kilometres, about an hour and fifty minutes in the air against seventeen to eighteen hours on a bus. Buenos Aires to Mendoza is 986 kilometres, an hour and fifty-five flying against thirteen to fifteen by road. El Calafate is a three-hour flight and a multi-day drive. There is also no practical direct land route from Iguazú to Mendoza or El Calafate; both connect through Buenos Aires.

They run regularly and they are comfortable, but they cost days rather than hours. Buenos Aires to Iguazú is seventeen to eighteen hours by bus, Mendoza thirteen to fifteen, and Bariloche about twenty across 1,621 kilometres against a two-hour flight. A bus earns its place when the overnight replaces a hotel night, or when the country between the towns is itself the reason for going. On a two-week itinerary, giving up three nights to the road is usually the wrong trade.

Count each region as a base of its own. Buenos Aires repays three or four days on foot across Recoleta, La Boca and the museums; Puerto Iguazú wants two nights so the Upper and Lower Circuits are not rushed; El Calafate needs two or three for Perito Moreno, more if El Chaltén is added 215 kilometres north. With internal flights linking them, a first trip taking in all three rarely works in under twelve days.

They can, but only as an air itinerary, and several connections route back through the capital, often changing airports there, since Ezeiza takes the international arrival while Aeroparque Jorge Newbery takes most domestic legs. No practical direct land link joins Iguazú to El Calafate. The second constraint is the calendar: the Patagonian season runs about November to March, so a July departure realistically becomes Buenos Aires and Iguazú, with the glaciers kept for another year.

Argentina lies in the southern hemisphere, so summer is December to February and winter June to August. Patagonia is usable roughly November to March, with most trails and lodges shut outside that window, and the wind blows hardest at the height of summer, which makes November and March the calmer ends of it. Buenos Aires turns hot and humid in January and February and is mildest in October and November or March and April. Iguazú is fullest in the wet months, about November to March.

The Argentine side is the walking day. From Puerto Iguazú the park gate is about 18 kilometres out, and the Upper and Lower Circuits plus the catwalk to the Devil's Throat put you among the drops for hours, with the Gran Aventura boat run beneath them. The Brazilian side at Foz do Iguaçu gives the panorama and a shorter visit. Crossing the tri-border, where Ciudad del Este in Paraguay is also a short drive over the bridges, means a different country and a different plan territory.

Out there, emptiness is the first explanation rather than a fault: the stretches of Ruta 40 between the southern towns are genuinely unpopulated, and the Iguazú park interior and the Alta Montaña climb west of Mendoza each have their own reason for a blank bar. Keep going and see whether it returns in the next town. If not, reopen the setup guide the plan came with, check the Argentina profile is switched on and picked as the data line, then hand support your order reference and handset model.
