eSIM for Argentina — Instant 4G/5G Data Plans

Argentina's mobile network is served by three main operators: Claro, Personal, and Movistar. 4G LTE coverage is widely available across Buenos Aires, Cordoba, Rosario, Mendoza, and most major cities, with coverage extending along principal highways and tourist routes. Patagonia, the Andean border regions, and remote rural areas may have limited 4G with some zones relying on 3G or having no signal at all. The vast geographic size of Argentina means coverage quality varies significantly between urban centres and the interior. MobiSIM connects through supported local networks to provide the best available data speeds for your location. Travellers on long-distance bus routes or road trips through less populated regions should download offline maps before departing each city.

Install your MobiSIM eSIM before landing at Ezeiza International Airport in Buenos Aires so you have data ready from arrival. Download offline maps for Buenos Aires, Patagonia, and any national parks you plan to visit, as signals can be unreliable in remote areas like Torres del Paine approach routes and Andean crossings. Keep your home SIM active for calls while MobiSIM handles your data. Argentina uses ARS currency with frequent exchange rate fluctuations, so having data access for banking apps and currency tools is especially useful. If you are travelling to El Calafate, Bariloche, or Ushuaia, note that connectivity improves in town centres but weakens quickly outside urban boundaries.
