Comparing SIM cards and travel eSIMs for Argentina

The network no eSIM will sell you

Argentina has three national carriers and a clear ranking between them. Personal leads on coverage — 92% of paved national routes — and has the widest 5G footprint at 18 cities. Movistar is second, averaging 41.4 Mbps. Claro is third. The national average across all three is about 45 Mbps.

The two sellers that tell us anything, eSIM Go and eSIMCard, both point at Movistar, Claro or both — and neither listing has been checked in either direction, because we have verified no prices for either company. Airalo, Nomad, Saily and Holafly publish no host network for Argentina — none of the four publishes one anywhere — so for them we cannot say. Either way, the best network in the country is available to you only if you walk into a shop and buy a local SIM.

For a city trip that is irrelevant. Movistar is perfectly good in Buenos Aires. For a Patagonia road trip it is the whole decision.

The local SIM: cheap in pesos, slower in practice

Personal, Movistar and Claro prepaid SIMs are sold at Buenos Aires Ezeiza, Córdoba and Mendoza airports and at carrier stores across the country. A passport is required for registration.

Prices run roughly ARS 3,000–8,000, which is about $3–8 at the parallel rate. A tourist data package bought at the airport counter is more like $15. That spread is the usual airport premium, and in Argentina it is worth noting that what you pay in dollars depends on how you changed your money in the first place.

Personal was the first Argentine carrier to offer a tourist eSIM, so buying local no longer necessarily means a plastic SIM — but it still means a counter and a passport.

What the travel eSIMs charge

Airalo sells Argentina under the package name Abrazo!, and those prices were read from Airalo's own site on 13 August 2026. The Nomad prices were read from Nomad's own site on 17 August 2026. The rest are indicative figures from our plan data.

That pattern has changed. An earlier version of this page said Nomad and Saily undercut Airalo at almost every size, and that Nomad's 20GB was $14 less than Airalo's for the same allowance. Nomad's prices have since been read off its own site, and they do not: Nomad and Airalo both charge $5 for 1GB and both charge $47 for 20GB. What Nomad gives you instead is validity — seven days on its 1GB against Airalo's three. Saily's indicative figures still undercut both in the middle of the range, on prices nobody has checked.

Holafly is the outlier, selling only unlimited: $19.90 for three days up to $89.50 for thirty. Unlimited has a real audience here, but Holafly does not support hotspot, and Argentina is a country where people tether laptops in cafés for hours.

Patagonia is where the choice bites

Coverage in Argentina is good along the routes and thin between them. The stretch from Bariloche to El Calafate has long signal-free sections across the steppe. Around Los Glaciares National Park, the Perito Moreno area is limited. Ushuaia itself is fine; the surroundings are not. The north-western Andean passes drop out too.

If your itinerary is Buenos Aires, Mendoza and Iguazú, buy a travel eSIM on price and stop thinking about it. If it is a self-drive through Patagonia, the case for walking into a Personal shop is genuine — not because the eSIMs are bad, but because they cannot sell you the network that covers the road.

The verdict

Short city trips: an eSIM, chosen on price. Airalo's verified 1GB over three days at $5.00 is the cheapest entry we can still point at — eSIMCard's cheaper row was withdrawn after we read its site and found the figure wrong.

Two weeks or more, or anything off the main routes: buy locally, and buy Personal. Our full plan tables and coverage notes are on the Argentina hub.
