How Does SIM Card & Internet Work in Argentina?
Last verified: 2025-06 · Americas
1The Quick Answer
Claro, Movistar, and Personal sell prepaid SIMs at airports and phone shops; coverage is good in cities but patchy in Patagonia.
2What You Need to Know
The three main carriers — Claro, Movistar, and Personal — all offer prepaid SIM cards with data packages. SIMs can be purchased at airports, carrier stores, or phone shops, and registration requires your passport. Airalo and other eSIM providers offer a convenient alternative for compatible unlocked phones. Mobile data and 4G coverage is strong in Buenos Aires and major cities, along main highways and tourist routes, but can be very limited or absent in remote Patagonia and the Andes. Pocket Wi-Fi rental is available at Buenos Aires Ezeiza airport.
3Practical Tips
Practical Tips
- 1Buy your SIM at the airport on arrival to have data connectivity from the moment you land.
- 2Download offline maps (Google Maps or Maps.me) for Patagonia before leaving areas with good coverage.
- 3If using an eSIM service like Airalo, activate it before you depart — setup requires a stable internet connection.
Important Warning
Connectivity in remote Patagonia and Tierra del Fuego can be essentially non-existent — download everything you need offline and inform someone of your itinerary before heading into the wilderness.
