Airalo eSIM for Argentina — Tango Package in 2026
Buenos Aires with La Boca and Palermo, the Perito Moreno glacier in El Calafate, the Iguazu falls, Mendoza wineries, the end of the world in Ushuaia — Argentina is a long country with massive distances, and a 2–3-week itinerary needs data every day. Local Movistar and Claro SIMs at Ezeiza (EZE) require a DNI national ID for full activation. Tourist eSIM kiosks exist but are slow. Airalo Tango installs at home and works the moment you land.
Available Airalo packages
The Argentina regional package is called Tango. Prices:
| Package | Data | Validity | Price |
