Argentina has Movistar as carrier. Movistar consistently ranks first for rural coverage — critical in a country the size of India with large uninhabited regions. In Buenos Aires, all three carriers offer similar urban 4G/5G performance. In Patagonia, the Andes, and Tierra del Fuego, Movistar's infrastructure advantage becomes decisive. Ovosim connects to Movistar with Personal as fallback.
Buenos Aires has excellent 4G/5G coverage throughout the city. The Buenos Aires Metro (Subte) — one of the oldest in the Americas — has cellular coverage on the main lines including Line A (the historic wooden-car line), Line B, and Line D. The trendy neighbourhoods of Palermo, San Telmo, Recoleta, and Puerto Madero all have strong signal. Download the BA Como Llego app for Buenos Aires public transport routing.
Patagonia is vast, sparsely populated, and some of the world's most dramatic wilderness. Coverage exists in the main towns: Bariloche, El Calafate, Puerto Madryn, Ushuaia, and Puerto Natales (just across the border in Chile). On the trekking routes themselves — the W Trek in Torres del Paine, the Huemul Circuit near Bariloche, or the Fitz Roy area near El Chaltén — expect no cellular signal. This is not a network failure; it is the honest reality of the Patagonian steppe. Download offline maps of every trek before leaving town.
The Mendoza wine region — home to Argentina's famous Malbec — has solid Movistar 4G coverage throughout the city and into the main wine valleys (Luján de Cuyo, Valle de Uco). The high-altitude vineyards near Tupungato and the Andean foothills approaching the Chilean border may have weaker signal. Most bodegas (wineries) have WiFi for guests, but having mobile data for navigation between estates on rural dirt roads is valuable.
The Iguazu Falls straddle the Argentina-Brazil border. The Argentine side (Puerto Iguazú) is covered by Movistar 4G. The Brazilian side (Foz do Iguaçu) is a different country — your Argentine eSIM will roam on Brazilian networks at international rates, or you'll need a Brazil eSIM for the Brazilian park entry. Most visitors do both sides in two days; check if your plan includes Brazil roaming.
Argentina's complex currency situation (official rate vs. blue dollar rate) affects many tourist transactions, but eSIMs purchased in euros or dollars before arrival are unaffected. You pay a stable international price, not the peso-denominated local rate. This is one of several reasons buying an eSIM before landing is advantageous in Argentina specifically.
