Where you will travel
In Patagonia the signal stays in town: on the trails and in the national parks you are offline, so save maps and tickets first.
- El Chaltén and Fitz Roy
- There is no mobile signal or Wi-Fi on the trails. In town, most places to stay have free Wi-Fi, too slow for video calls.
- Perito Moreno Glacier
- Don’t count on internet in Los Glaciares National Park. Hotels, restaurants and cafés in El Calafate have Wi-Fi.
- Tierra del Fuego National Park
- There is no mobile signal in the park, except around Cañadón del Toro and the Pipo valley.
Arriving in Argentina
A local SIM needs your passport: the law requires every line to be registered, and the store does it when you buy. With the eSIM installed at home, you skip the stand.

Questions about eSIM in Argentina
Which eSIM should I get for Argentina?
The South America eSIM on this page: one prepaid plan for Peru, Argentina, Chile, Brazil and Ecuador. Choose the days of your trip and the data you need, and the QR code appears seconds after payment.
Is the Argentina eSIM an Argentine line?
No. For Argentina we sell the South America eSIM, which roams on a partner network in each country it covers: turn on data roaming for the eSIM line, and your phone shows that network’s name.
Does it keep working when I cross a border?
Yes. The same eSIM works in Argentina, Peru, Chile, Brazil and Ecuador, so there is no new plan to buy in each country.
Can I buy a SIM at the airport in Buenos Aires?
At Ezeiza, only Personal has an official stand, in departures near check-in counter 40; it asks for your passport and usually takes cards only. Aeroparque’s list of shops has no phone shop. The South America eSIM on this page skips both: you install it at home.
Do I need to turn on data roaming?
Yes, for the eSIM line only: the plan roams on a partner network in each country. Keep data roaming off on your usual SIM, so your home carrier cannot charge you for roaming.
Can I keep my WhatsApp number?
Yes. Your usual SIM stays in your phone with your number for calls and texts, and WhatsApp keeps the same number while the eSIM carries your data.
What if the eSIM does not work?
You get a full refund if it does not work and we cannot fix it, or if it is not delivered. Write to contact@esimamericas.com with your order link.

In each country on the list it roams on a partner network, and your phone shows that network's name, so turn on data roaming for the eSIM line when you land. The mobile networks in Argentina are Personal, Claro and Movistar. An Argentina SIM card from the airport means a queue after landing. You install this eSIM at home, before you fly.
You pay by card, and the QR code appears on your order page seconds after payment: bookmark that page or save the QR code before you leave it. Then you add the eSIM to your phone. When you land, choose the eSIM line for mobile data and keep your own number for calls and texts. Full refund if it does not work. The steps for iPhone and Android are in the help centre.
