eSIM for Argentina
Argentina runs on the phone, and on the exchange rate. Inflation ran at 211% in 2023 and 118% in 2024 before falling to about 32% by late 2025 (INDEC). Prices still move every month, menus are QR codes, and locals pay with Mercado Pago or a card. Foreign cards now get a fair rate, but a tourist without data cannot check it, order the Cabify or read the menu.
Local SIMs must be registered to a passport at an operator store. Movistar does not sell prepaid at its shops at all, and the only counter at Ezeiza airport is Personal's. A FairSIM eSIM for Argentina connects to Personal, Movistar or Claro at the wholesale rate, installs before you fly and skips the registration.
Beyond Buenos Aires the country is enormous. Ruta 40 has 50 to 100 km gaps between towns with no signal on any network, and Tierra del Fuego National Park has coverage only at the gate. The North America plan also covers Chile and Uruguay, which matters if Torres del Paine or Colonia is on the list.

How FairSIM works
- 1
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
- 2
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
- 3
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Connectivity tips for Argentina
Ruta 40 has 50 to 100 km stretches with no signal between El Bolsón, Esquel, Perito Moreno and El Chaltén. Download offline maps and your bookings before leaving Bariloche or El Calafate.
Tierra del Fuego National Park has coverage only at the entrance, and the glacier walkways at Perito Moreno are patchy. Screenshot your tickets.
Phone snatching is common in crowded Buenos Aires, on Florida street and around Retiro. Use the map inside a café and keep the phone in a front pocket.
Pay by card or Apple Pay. Foreign cards get a rate close to the market one, Mercado Pago needs an Argentine account, and the old advantage of dollar cash has mostly gone.
Prices change monthly. Check the peso rate in an app before agreeing a remis fare or a hotel bill in cash.
Uber, Cabify and DiDi work in the big cities. In El Calafate, El Chaltén and Ushuaia you book remises over WhatsApp, which needs data.
Crossing to Chile for Torres del Paine, or to Uruguay on the Colonia ferry? Choose the North America plan and the eSIM keeps working across the border.
Argentina stays on UTC−3 all year, so a Patagonian summer sunrise comes before 6 am. Keep automatic time zone on for flights from Ezeiza and Aeroparque.
Apps you will actually use
- WhatsApp hotels, remises, wineries and tour guides all book here.
- Cabify, Uber and DiDi all three work in Buenos Aires, Córdoba, Mendoza and Rosario; Patagonian towns rely on remises.
- Google Maps live Subte and colectivo times in Buenos Aires; download offline areas for Patagonia.
- Mercado Pago the QR payment app locals use; it needs an Argentine account, so tourists pay by card instead.
- Google Translate the Spanish offline pack for menus and bus stations.
- Plataforma 10 or Busbud long-distance bus tickets, still the backbone of domestic travel.
- Aerolíneas Argentinas, Flybondi and JetSmart domestic flights and boarding passes.
- Windguru or Windy wind forecasts before a Patagonia hike or a glacier boat.
Mercado Pago QR codes are everywhere but only work with an Argentine account. Foreign cards are widely accepted and get a rate close to the market one, so tap-to-pay beats changing dollars.
Can you rely on free Wi-Fi?
Free Wi-Fi is easy in Buenos Aires: cafés, hotels, the airports and the city's public hotspots in parks and Subte stations. In Patagonia it shrinks to hotel lobbies and is often too slow for a photo upload. Do not rely on it for maps on the road.
Local SIM card or eSIM in Argentina?
Prepaid packs are cheap once you hold the SIM: Personal's tourist pack gives 3 GB for 30 days at about 5,900 pesos (US$4), Claro 10 GB for about 15,000 pesos (US$10). The catch is the process. Every prepaid line must be registered to a passport at an official store, Movistar shops do not sell prepaid at all, and the only airport counter at Ezeiza is Personal's. Kiosks sell SIMs but cannot register them.
A FairSIM eSIM connects to Personal, Movistar or Claro at the wholesale rate with no store, no passport copy and no peso price that changes next month. Install it on Wi-Fi at home, and it is working when you clear immigration at Ezeiza.

Argentina eSIM questions
Does eSIM work in Argentina?
Yes. Personal, Movistar and Claro all support eSIM, and any unlocked eSIM iPhone connects. FairSIM installs in one tap and activates on your first connection in Argentina.
Which network will my FairSIM eSIM use in Argentina?
Plans connect to Personal, Movistar or Claro. Personal is fastest and strongest in Patagonia, Movistar and Claro match it in the cities. The app shows the network for each plan.
Is there 5G in Argentina?
Yes, in Buenos Aires, Córdoba, Rosario, Mendoza, Mar del Plata and a handful of other cities, mostly on Personal and Claro. Most travel eSIMs run on 4G LTE, which reaches every town and paved national route.
Can I use my eSIM as a hotspot?
Most FairSIM plans support Personal Hotspot; the app confirms it per plan. Useful when the estancia Wi-Fi cannot handle a video call.
Should I install the eSIM before or after landing?
Install it at home on Wi-Fi in one tap, keep it off, then enable data on it when you land. Validity typically starts on the first connection in Argentina.
Can I make calls and use WhatsApp?
WhatsApp calls and messages work fully over data, and every remis, hostel and winery uses it. There is no Argentine number, so keep your home SIM for SMS codes.
How much data for 7, 14 or 30 days?
Buenos Aires city break: 5, 10 and 20 GB. Patagonia or Mendoza with offline maps: 3, 6 and 12 GB. Remote work with hotspot: 10, 20 GB, then unlimited. Top up in the app at any time.
Local SIM or travel eSIM for Argentina?
A local SIM is cheap but must be registered to your passport at an official store, and Movistar shops do not sell prepaid at all. A travel eSIM needs no registration, is set up before departure, and runs on the same networks.
Does it work in Chile and Uruguay too?
Choose the North America plan. It covers Argentina, Chile, Uruguay and Brazil, so Torres del Paine, Colonia and the Brazilian side of Iguazú switch networks automatically at the border.
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer. iOS 17.4 or later unlocks the one-tap install with no QR code. Check the full list on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
