The best eSIM for Argentina and Uruguay in 2026.

Argentina and Uruguay are a ferry apart across the Rio de la Plata, and one regional eSIM covers both, so the boat to Colonia needs no new plan. I priced six brands on the same day and say where Ringo Light costs more.

Cheapest unlimited eSIM for Argentina and Uruguay: Ringo Light, $47.99 for 2 weeks and $65.99 for 30 days (Airalo $60 and $97). Prices read 25 October 2026.

The short answer

The usual Argentina and Uruguay trip starts in Buenos Aires and takes the ferry across the Rio de la Plata to Colonia del Sacramento, then Montevideo and the coast to Punta del Este. I priced the Latin America regional plans of six brands on the same day and read the fine print on unlimited. For two weeks or a month I would buy Ringo Light. For three days, a bucket, or Uruguay alone, a rival is cheaper.

What to do in Argentina and Uruguay, and what your phone needs for it

Eight places an Argentina and Uruguay trip often includes, four on each bank of the Rio de la Plata, with what your data does for you at each. Both are on Ringo Light's list. Signal is good in the cities and thin on the coast and in the parks, so a few tips are about offline maps.

Caminito, La Boca, Buenos Aires
La Boca, Buenos AiresCaminitoA short street of painted wood and tin houses in the old port district, with tango on the pavement and art stalls. Go by day and stay around the main streets.✓Uber and Cabify both work in Buenos Aires. A ride in and out of La Boca is the easy way.
Iguazu Falls and the Devil's Throat, Puerto Iguazu, Misiones
Puerto Iguazu, MisionesIguazu Falls and the Devil's ThroatOn the Argentine side a small train and a long walkway take you to the edge of the Devil's Throat, where the river drops into a horseshoe of falls. Plan a full day for the trails.✓An Argentina plan stops at the border. If you cross to the Brazilian side, check your eSIM covers Brazil too.
The vineyards of Mendoza, Mendoza and the Uco Valley
Mendoza and the Uco ValleyThe vineyards of MendozaMost of Argentina's Malbec grows here, on vineyards at the foot of the Andes. Harvest runs from February to April.✓Many wineries take visitors by booking only. Reserve tastings online or on WhatsApp the day before.
The lakes around Bariloche, San Carlos de Bariloche, Rio Negro
San Carlos de Bariloche, Rio NegroThe lakes around BarilocheBariloche sits on Lake Nahuel Huapi, ringed by forest and snowy peaks. Drive the Circuito Chico loop or take the chairlift up Cerro Campanario for the view.✓A maps app marks the viewpoints on the Circuito Chico, so you know where to stop.
Plaza Independencia and Palacio Salvo, Montevideo
MontevideoPlaza Independencia and Palacio SalvoThe main square of the capital, with the statue of Artigas and the tower of Palacio Salvo, finished in 1928. The old stone gate on its west side leads into the Ciudad Vieja.✓Uber works in Montevideo, and a route app shows which city bus to take.
Barrio Historico of Colonia del Sacramento, Colonia
ColoniaBarrio Historico of Colonia del SacramentoCobbled lanes and low houses from the Portuguese town founded in 1680, a UNESCO site on the river. About two and a half hours by bus from Montevideo, or a ferry ride from Buenos Aires.✓Keep your ferry or bus ticket on your phone, and remember a Uruguay-only eSIM stops at the Argentine border.
La Mano on Playa Brava, Punta del Este
Punta del EsteLa Mano on Playa BravaFive concrete fingers rising from the sand, by the Chilean artist Mario Irarrazabal, on the Atlantic side of the peninsula. The town is at its fullest in January.✓In high summer beds and tables go fast. Book them on your phone well ahead.
Cabo Polonio, Rocha
RochaCabo PolonioA cape of dunes, a lighthouse and a sea lion colony, with no road in: open trucks carry you across the dunes from the entrance on Route 10.✓Most houses run on little or no mains power. Bring a charged power bank and download offline maps before the truck.

One plan for both banks of the river: Ringo Light

The Buenos Aires to Colonia ferry takes about an hour, and a country eSIM leaves you on roaming or no data on the far side. A regional eSIM carries on when the boat docks. You also keep one install and one bill for a trip that is short on days.

For about two weeks of unlimited, Airalo asks $60 and Holafly $62.90, both for 15 days, against $47.99 for 2 weeks at Ringo Light. For a month, Airalo asks $97, Ubigi $99 and Holafly $99.90, against $65.99. Nothing renews, and I would buy it for this route.

Two country plans cost a lot more because Uruguay is the dear one. Argentina's 2 weeks is $44.99 and Uruguay's $50.99 on their own pages, $95.98 together, against $47.99 for the Latin America trip that covers both. A month is $56.99 plus $86.99, $143.98, against $65.99.

Rivals win in places. Airalo's 7 days of unlimited is $39 and Holafly's $40.90, under Ringo Light's 2 weeks. For Argentina alone, Ringo Light's own page at $44.99 beats its regional plan, so read that instead.

Which plans cover both countries

Ringo Light's 18 countries include Argentina and Uruguay. Airalo's Latamlink and Nomad list 17 countries, Holafly 18, Saily 12 and Ubigi 15. I could not confirm Argentina or Uruguay on each rival's list on the day, because the page I priced from names only the gaps it found.

The gaps named there are not on your route: Saily skips Guatemala, Honduras, Nicaragua and Panama, and Ubigi skips Peru and Costa Rica. So I found no sign that any of the six drops Argentina or Uruguay, but I would check both on the brand's own list.

Buenos Aires, Montevideo, Colonia and the Punta del Este coast are well covered. Signal thins in the Patagonian parks, on the Rocha beaches and on the river itself. I would download offline maps before the ferry or a long drive.

If you want a data bucket: Airalo or Ubigi

  • Airalo, $36 for 10 GB. The cheapest 10 GB regional bucket, and $49 for 20 GB. Latamlink also sells 5 GB for 30 days at $22.
  • Ubigi, $39 for 10 GB. 25 GB for 30 days at $58, or a monthly 20 GB at $26 that renews with a 3-month minimum. A fair choice for a long stay in Buenos Aires.
  • Nomad, $39 for 10 GB. 20 GB for $65 on Claro, Tigo, Telcel and other local networks.
  • Saily, up to 10 GB. 10 GB for 30 days at $44.99, 5 GB at $31.99 and 3 GB at $20.99. It sells no 20 GB bucket and no unlimited plan for the region.
  • ✓Ringo Light, no buckets. It sells unlimited only: 2 weeks at $47.99 and 30 days at $65.99. Airalo, Nomad, Ubigi and Saily all sell 10 GB for less than its 2 weeks, and Airalo at $49 and Ubigi at $58 beat its month on 20 GB. I would buy Ringo Light for unlimited, and a bucket elsewhere.

What Ringo Light is

Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so weigh that. For Latin America it sells 2 weeks at $47.99 and 30 days at $65.99, both unlimited at full speed across 18 countries. Nothing renews. The eSIM comes by email in seconds and installs in one scan, no app.

The card to buy it is further up this page, just after the side-by-side table.

Frequently asked questions

Does one eSIM work in both Argentina and Uruguay?+
Yes, on a Latin America regional plan that lists both, and Ringo Light does. I could not confirm both on every rival list on the day, so check the brand's own page before you buy.
Which eSIM is cheapest for an Argentina and Uruguay trip?+
For two weeks or a month of unlimited, Ringo Light: $47.99 and $65.99 on 25 October 2026. For 3 days, Airalo at $19.50. For a 20 GB bucket, Airalo at $49.
Is unlimited really unlimited?+
Each brand has a limit somewhere. Airalo slows you after 3 GB a day, Ubigi after 60 GB on the month. Holafly states no daily cap on your own phone. Ringo Light is unlimited at full speed, and I count that in my pick.
Should I buy two country eSIMs instead?+
I would not. Argentina's 2 weeks is $44.99 and Uruguay's $50.99 on their own pages, $95.98 together, against $47.99 for the regional trip. I read both pages to make that sum. One country only is different.
