Best eSIM for Argentina (2026): 7 providers compared

For most trips to Argentina, the cheapest fixed-data eSIM we found is NomadGB: $10.99 for 5GB, $17.99 for 10GB and $30.49 for 20GB, all valid 30 days, on Claro and Movistar. Ubigi is the next cheapest at $21 for 10GB. For "unlimited" data, Maya Mobile is cheapest at $19.99 for 7 days (5GB a day at full speed); our own 3GB-a-day plan at $60.49 a week is the most expensive option here.

How we compared: prices come from each provider's own website on 13 November 2026, and from our own catalog the same week. We compared the cheapest plan, about 5GB, 10GB and 20GB, the "unlimited" or daily plan for about a week, and which Argentine networks each eSIM uses. Saily's site blocks automated checks, so its prices are "not checked".

Best for each need

NomadGB: cheapest fixed data, two networks

Our Argentina eSIM costs $10.99 for 5GB, $17.99 for 10GB and $30.49 for 20GB, all valid 30 days. It is the only eSIM in this table that lists both Claro and Movistar, so your phone can switch when one is weak. That helps in Patagonia and in the north. Our weak point is unlimited data: $60.49 for 7 days with a 3GB daily cap is the priciest weekly plan here. Heavy users should look at Maya or Airalo.

Maya Mobile: cheapest unlimited

Maya Mobile costs $19.99 for 7 days and $49.99 for 30 days. Full speed lasts 5GB a day, then 3 Mbps. It runs on Claro, the largest network in Argentina by subscribers. Maya sells one price for every country, so there is no small cheap plan.

Ubigi: second cheapest for 10GB

Ubigi charges $21 for 10GB over 7 days, $23 for 10GB over 30 days, and $44 for 25GB over 30 days. It uses Movistar and states that hotspot is allowed. Its unlimited week is $35 with 20GB at full speed.

Airalo: flexible short plans

Airalo has many sizes, from 1GB for 3 days at $5 to an unlimited week at $34.50 (3GB a day at full speed). It runs on Movistar. For 10GB it costs $28 for 7 days, which is more than Ubigi or us.

Nomad: 30-day plans on Movistar

Nomad (nomadesim.com, the getnomad.app company, not our brand NomadGB) charges $16 for 5GB, $28 for 10GB and $47 for 20GB, all 30 days. It has no unlimited Argentina plan. Prices are above Ubigi and ours.

Holafly and Saily

Holafly costs $36.90 for 7 days on Telefonica (Movistar), with no stated daily cap but a 1GB daily hotspot limit. Saily, from Nord Security, blocked our price check. Its app adds an ad blocker and virtual location, which some travelers like.

Mobile networks in Argentina

Argentina has three networks: Claro, Personal and Movistar. Before a recent merger, Argentina's competition authority put their shares at 41.8% for Claro, 33.8% for Personal and 24.4% for Movistar. In February 2025 Telecom Argentina, which owns Personal, bought Telefónica's Argentine business, including Movistar. In June 2026 the competition tribunal approved the deal only with conditions: Telecom must hand six million mobile customers and spectrum to a new competitor within 18 months. For travelers this means little today, but network names and roaming deals may change in 2027.

No eSIM in this table lists Personal. In practice you choose between Claro and Movistar. Both cover Buenos Aires, Mendoza, Córdoba, Salta and the main Patagonian towns well. Between towns, especially on Ruta 40 and in national parks, coverage drops to nothing for long stretches on every network. An eSIM with two networks (ours) gives you a second chance, but no eSIM fixes a road without towers. Download offline maps before you drive.

Which one should you pick?

• Short trip, light use: NomadGB 1GB for $2.99 or 5GB for $10.99.
• 2 to 4 weeks, normal use: NomadGB 10GB for $17.99 or 20GB for $30.49.
• Heavy data or streaming: Maya at $19.99 a week or $49.99 a month, with a 5GB daily cap.
• Hotspot for a laptop: Ubigi or Maya, both state hotspot is allowed.
• Patagonia road trip: a two-network plan (NomadGB) plus offline maps.
• Need a phone number: none of the plans here includes an Argentine number.
