You switch on your phone in São Paulo. Two texts arrive: the welcome message from your carrier, then the out-of-EU roaming rates. South America has no equivalent agreement to the European zone. The result: foreign subscribers pay some of the highest rates in the world.
A South America eSIM bypasses all of that. You buy your plan from home, the profile installs on your phone in a few minutes, and the meter only starts at the first MB consumed at your destination. You know exactly what you're paying before you board. That's it.
With Kolet, plans start at €3.99 and cover up to 14 Latin American countries in a single plan. No plastic SIM to hunt down in a foreign airport, no queuing at a carrier counter.
Brazil, Argentina, Colombia: three countries, three network realities. Here's the essentials before choosing your data volume.
Brazil
- Solid 4G coverage in São Paulo, Rio and Brasília
- Outside main corridors, quality varies significantly
- Recommended volume: minimum 5 GB for two weeks with standard usage
Argentina
- Buenos Aires: good 4G coverage in the city centre
- Patagonia: large areas on 3G or with no signal
- Recommended volume: 3 GB is enough for an urban stay, with a no-reinstall top-up option if you head south
Colombia
- Bogotá, Medellín, Cartagena: reliable coverage
- Natural parks and rural areas: proceed with caution
- Recommended volume: 5 GB for two to three weeks split between cities and nature
Kolet offers plans from 1 GB to 20 GB, valid for 30 days from first connection. The Latin America eSIM plan covers 14 destinations (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Mexico, Panama, Paraguay, Peru, Uruguay) from €6.99. Check kolet.com for exact prices.
This is the point nobody mentions in eSIM comparisons.
With most travel plans, arriving back home with 2 GB unused means 2 GB lost. Kolet works differently: when your plan expires, remaining data automatically converts into Koins, the app's internal currency. €1 equals 100 Koins, reusable for a future trip, a top-up or international calls. Nothing evaporates.
Bogotá, Buenos Aires, São Paulo on the same trip? No need for three different eSIMs or to reinstall anything between borders. A single Kolet profile covers 190+ destinations: you change your plan in the app, the profile stays in place.
Since March 2026, Kolet also offers internet-based international calls, billed per minute and payable in Koins. Calling a local contact from Medellín or Buenos Aires without a local SIM card is now possible directly from the app.
Do you travel regularly and have a Flying Blue card? You earn 10 miles per euro spent with Kolet, and you can pay for your plans with your miles. Handy when your next flight leaves in two weeks.
No intention of criticising the competition without solid grounds. Here's what is verifiable.
- Holafly: offers "unlimited" plans, but with speed throttling after a certain consumption threshold. Kolet has no throttling.
- Airalo: a transactional marketplace, with no airline integration or loyalty programme.
- Saily: backed by Nord Security, with no miles and no unused data recovery system.
Kolet is also the only major travel eSIM that is B Corp certified (score 99.7/200, obtained in January 2026). For travellers who care about the impact of their purchases, this is a criterion that matters.
