eSIM for Argentina

eSIM, roaming or a local SIM in Argentina

There are three ways to stay connected, and the right one depends on your trip length, budget and tolerance for paperwork on arrival.

How much data to plan for

Argentina trips are often long and spread out, with lots of time on buses and planes. Usage figures are approximate:

• Maps and navigation: a few megabytes per hour; essential in big cities and for road trips.
• Messaging: light. WhatsApp is the standard way to contact hostels, tour operators, drivers and even many shops and restaurants in Argentina.
• Ride-hailing and transport apps: light, but you need them to work when you are standing on the street.
• Social media: moderate to heavy with video.
• Video calls: typically several hundred megabytes per hour.
• Streaming: heavy, often a gigabyte or more per hour in high definition.

Before you go

Install the eSIM at home on Wi-Fi, because you need a connection to download it. First check your phone supports eSIM and is carrier-unlocked.

Then follow the install guide for iPhone, Samsung or Pixel. Label the line "Argentina", keep your home SIM as default for calls and texts, and set the Spidot line for mobile data.

• Install the eSIM a day or two before departure.
• Download offline maps for every region you will visit, especially Patagonia and the north-west.
• Download a Spanish language pack in your translation app.
• Save bus tickets, flight bookings and accommodation addresses offline.
• Turn off data roaming on your home SIM.

Arriving in Argentina

Most long-haul flights land at Ministro Pistarini International Airport, usually called Ezeiza, south-west of Buenos Aires. Jorge Newbery Airport, known as Aeroparque, is right by the river in the city and handles most domestic flights and some regional ones. Many travellers fly into Ezeiza and out of Aeroparque on the same day, so check which airport your connection uses.

When you land, select the Spidot line for mobile data and turn on data roaming for it. Our data roaming guide shows where to find the setting. If it does not connect within a couple of minutes, switch flight mode on and off once.

Coverage in cities, the Andes and Patagonia

In Buenos Aires, Córdoba, Rosario, Mendoza, Salta and other cities, mobile data generally works as you would expect. Tourist towns such as Bariloche, El Calafate, Puerto Iguazú and Ushuaia are usually covered too. In Argentina, the Spidot eSIM connects to Movistar.

Argentina is enormous and sparsely populated outside the cities, and long stretches between towns can have weak or no signal.

• Patagonian highways: Ruta 40 and the roads across the steppe can go for hours without coverage between settlements.
• El Chaltén trails: the town has signal, but the hikes to Laguna de los Tres and Laguna Torre go out of range quickly.
• Glaciers and national parks: visitor centres and viewpoints may have coverage, but much of the parkland does not.
• The north-west: valleys in the Quebrada de Humahuaca and the high roads towards the salt flats and the Puna can have long gaps.
• The Andes: mountain passes, including crossings to Chile, often have little or no signal.
• Iguazú: the falls area is visited by many people, so coverage near facilities is usually present, but trails through the forest can vary.

Data on buses, flights and road trips

Long-distance buses are the backbone of Argentine travel, with comfortable overnight services between major cities. Domestic flights save days on long routes, for example from Buenos Aires to Patagonia or Iguazú. In Buenos Aires itself, the Subte metro, city buses (colectivos) and trains are paid with the rechargeable SUBE card.

On long bus journeys, data comes and goes: expect good coverage near cities and long gaps in between. Download podcasts, music and series before you board, and keep your ticket and booking confirmation offline.

Sharing data with a hotspot

Hostel and guesthouse Wi-Fi in Argentina can be slow, especially in remote areas where it may run over a limited connection. Your phone's personal hotspot can connect a laptop or tablet. It shares the line selected for mobile data, so make sure that is the Spidot line.

Tethering a laptop uses a lot more data than a phone. Pause cloud sync, automatic updates and photo backups before connecting, and keep an eye on your balance.

Using public Wi-Fi safely

Cafés, hotels, bus stations and some public spaces offer free Wi-Fi. It is useful, but open networks can be insecure.

• Use your eSIM data for banking, payments and logins.
• Check the exact network name before connecting.
• Turn off automatic joining of open networks.
• Keep your phone and apps updated before travelling.

Practical tips for Argentina

A few local details that make data especially useful:

• Money: Argentina's currency is the peso, and the rules and rates for paying by card, withdrawing cash or exchanging money have changed often in recent years. Check up-to-date advice just before you travel, and use data on the ground to compare options.
• Digital payments: QR code payments and apps such as Mercado Pago are widely used by locals. Card payments are accepted in many places, but carry some cash for small shops, markets and rural areas.
• Late hours: dinner often starts late in the evening, especially in Buenos Aires. Check opening hours online before setting off.
• Phone safety: in busy areas of Buenos Aires and other cities, keep your phone out of sight on the street and on public transport, and be careful when using it near the kerb.
• Seasons: Patagonia's main season is the southern summer, roughly December to March, while the north-west and Iguazú are pleasant in the cooler months. Weather in the south changes quickly, and wind is a constant.
• Language: Spanish is the main language, with a distinctive Argentine accent and vocabulary. English is common in tourist businesses in Buenos Aires but less so elsewhere.

Argentina on a multi-country trip

Argentina combines naturally with its neighbours. Many travellers cross the Andes to Chile, take the ferry to Uruguay, see the Brazilian side of the Iguazú Falls in Brazil, or travel north to Bolivia and Paraguay.

For a route through several countries, install one eSIM per country before you leave home. Most eSIM phones can store several, and you switch mobile data to the right line when you cross the border. Near borders, check the network name in your settings to be sure which line you are using.
