The short answer
Argentina and Chile share the longest border in South America, and most trips cross it: Buenos Aires and Mendoza over to Santiago, or El Calafate over to Torres del Paine. I priced the Latin America regional plans of six brands on the same day and read how each one limits unlimited. For two weeks or a month I would buy Ringo Light. For three days or a bucket, a rival is cheaper.
Unlimited data at full speed, one eSIM that covers Argentina and Chile among 18 countries: 2 weeks at $47.99 or 30 days at $65.99, nothing renews. Airalo asks $60 for 15 days and $97 for the month.
3 days of unlimited at $19.50 with 3 GB a day at full speed, 5 GB for 30 days at $22 and 20 GB at $49, on a plan of 17 countries.
Days, not gigabytes, in 18 countries. $40.90 for a week; sharing limited to 1 GB a day.
20 GB a month for $26 on a monthly plan that renews and can be cancelled after 3 months. Its Best LATAM plan leaves out Peru and Costa Rica.
Prices read on 25 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in Argentina and Chile, and what your phone needs for it
Eight places that first trips to Argentina and Chile often include, from Buenos Aires to Patagonia, with the one thing your phone does for you at each. The towns have good signal. The glaciers and the national parks do not, so I would save maps and tickets offline.
One plan for both countries: Ringo Light
I would buy one regional eSIM for this trip, not two country ones. The border crossings are long bus rides or a flight over the Andes, and the last thing I want at the other end is to find wifi to install a second plan. Ringo Light's Latin America plan costs $47.99 for 2 weeks and $65.99 for 30 days, unlimited data at full speed, and nothing renews. Airalo asks $60 for 15 days and $97 for the month. Holafly asks $62.90 and $99.90.
I added up Ringo Light's country plans from their own pages. Argentina's 2 weeks is $44.99 and Chile's is $44.99, $89.98 together, against $47.99 for the Latin America trip that covers both. For a month, Argentina is $56.99 and Chile $63.99, $120.98 together, against $65.99.
There is one exception, and it favours the country plans. If you spend a whole month in only one of the two, Argentina's 30 days at $56.99 and Chile's at $63.99 both cost less than the regional $65.99. I would only take that route if you are sure you will not cross.
Which plans cover both countries
Ringo Light covers Argentina and Chile on its 18-country eSIM, along with Peru, Bolivia, Brazil, Uruguay and the rest of the list in the Latin America post. The other five brands sell regional plans too. The Latin America post does not list Argentina and Chile for each of them one by one, so I could not confirm both countries on every rival's list on the day, and I would check each list before buying.
What I can say from that post: Ubigi's Best LATAM plan leaves out Peru and Costa Rica, and Saily's covers 12 countries and skips four in Central America. Neither is a reason to worry about this route, but the rule holds. Coverage is good in the cities. It thins out on the Andean passes, along the Carretera Austral and inside the Patagonian parks, whichever eSIM you carry, so I would download offline maps before those days.
If you want a data bucket: Airalo or Ubigi
- Airalo, $36 for 10 GB. The cheapest 10 GB here, and the cheapest 20 GB at $49. Latamlink also sells 5 GB for 30 days at $22.
- Ubigi, $39 for 10 GB. 25 GB for 30 days at $58. For three months or more, its monthly plan gives 20 GB for $26 a month, renewing, with a 3-month minimum.
- Nomad, $39 for 10 GB. 20 GB at $65, on Claro, Tigo, Telcel and other local networks.
- Saily, up to 10 GB. 10 GB for 30 days at $44.99, with 5 GB at $31.99 and 3 GB at $20.99. No 20 GB and no unlimited plan for the region.
- ✓Ringo Light, no buckets. For 10 GB, Airalo at $36, Nomad at $39 and Ubigi at $39 all cost less than Ringo Light's 2 weeks at $47.99. For 20 GB across a month, Airalo at $49 is cheaper than its $65.99. Buy Ringo Light for unlimited, not for a bucket. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan with your own number ported onto it. I write for Ringo, so weigh that. For Argentina and Chile it sells two trips on one eSIM that works across 18 countries, both unlimited data at full speed: 2 weeks at $47.99 and 30 days at $65.99. Nothing renews. The eSIM arrives by email and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Airalo Latamlink unlimited, 3 days, $19.50, with 3 GB a day at full speed. Ringo Light sells no 3 days.
Airalo, 7 days of unlimited at $39, or Holafly at $40.90. Both are under Ringo Light's 2 weeks.
Ringo Light unlimited, 2 weeks, $47.99, against $60 for 15 days at Airalo.
Ringo Light unlimited, 30 days, $65.99, against $97 at Airalo.
Airalo 5 GB for 30 days at $22, or 20 GB at $49.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
