Best eSIM for Patagonia (2026): 7 providers compared

For a trip to Argentine Patagonia, the cheapest fixed-data eSIM we found is NomadGB at $17.99 for 10GB over 30 days, and it is the only one here that uses both Claro and Movistar. If your route also crosses into Chile (Torres del Paine, Puerto Natales, the Carretera Austral), a plan that covers both countries is simpler: Maya Mobile at $19.99 a week or $49.99 a month, or Airalo's Latin America plan at $49 for 20GB over 30 days. Whatever you buy, expect no signal on most trails and long stretches of road.

How we compared: prices come from each provider's own website on 13 November 2026, and from our own catalog the same week. Patagonia is split between Argentina and Chile, so we compared Argentina plans in the table, then two-country options below. We also read recent traveler and tour operator reports on where phones actually work. We did not check Yesim's prices.

Where your phone works in Patagonia

Coverage in Patagonia depends far more on where you are than on which eSIM you buy. Tour operator Swoop says large towns have almost complete coverage, while the roads between them, fjord cruises and national parks have little or no signal. Strong wind can also cut the signal. A 2026 traveler guide from LatamTravellers adds detail:

• El Calafate: solid 4G in town. Signal at the Perito Moreno Glacier viewing platforms is inconsistent.
• El Chaltén: the village usually has 3G or 4G, but it can drop. There is generally no coverage on the trails to Laguna de los Tres or Laguna Torre; expect to lose it within the first kilometer.
• Ushuaia: good 4G across the city. Tierra del Fuego National Park has little or no coverage on its trails.
• Ruta 40: very patchy, with gaps of 200 to 300 km and signal mainly at fuel stops.
• Torres del Paine (Chile): very limited. The W Trek and O Circuit are almost entirely without signal. Some refugios sell slow satellite Wi-Fi by the session.
• Puerto Natales (Chile): reliable 4G in the center.
• Carretera Austral (Chile): minimal coverage outside towns such as Coyhaique, Chaitén and Futaleufú.

What this means: a two-network eSIM gives you a better chance in small towns, but no eSIM can fix a valley without towers. Download offline maps, your bus and park tickets, and any trail notes before you leave town.

Best for each need

NomadGB: cheapest data for Argentine Patagonia

Our Argentina eSIM costs $10.99 for 5GB and $17.99 for 10GB, valid 30 days, on Claro and Movistar. Having both networks helps in small towns where one of them is weak. If you cross into Chile, add our Chile plan (also $17.99 for 10GB) or choose our South America plan. Our weak spot is unlimited data: $60.49 a week is the most expensive option in the table.

Maya Mobile: one plan for Argentina and Chile

Maya Mobile sells one global plan, so the same eSIM works on both sides of the border. It costs $19.99 for 7 days, $27.99 for 14 days or $49.99 for 30 days, with 5GB a day at full speed. In Argentina it uses Claro only.

Airalo: regional plan for border crossers

Airalo's Latin America plan covers Argentina and Chile. It costs $36 for 10GB or $49 for 20GB over 30 days. Its Argentina-only plans run on Movistar and cost more than ours.

Ubigi: most data per dollar on a long trip

Ubigi sells 25GB for 30 days at $44 in Argentina, on Movistar, with hotspot allowed.

Nomad, Holafly and Yesim

Nomad (nomadesim.com, the getnomad.app company, not our brand NomadGB) charges $28 for 10GB over 30 days on Movistar; its 17-country Latin America plan also covers Chile. Holafly costs $36.90 a week on Movistar with no stated daily cap. Yesim, a Swiss provider with pay-as-you-go data, also sells Argentina plans; we did not check its prices.

Which one should you pick?

• Argentina only (El Calafate, El Chaltén, Ushuaia): NomadGB 10GB for $17.99.
• Argentina plus Torres del Paine: Maya's global plan, Airalo's Latin America plan, or our Argentina and Chile plans together.
• Heavy data for photos and video uploads: Maya at $49.99 for 30 days, with a 5GB daily cap.
• Hotspot for a laptop: Ubigi or Maya.
• Remote treks and long drives: any eSIM plus offline maps. For emergencies, carry a satellite messenger; phones will not help on most trails.
