Best eSIM for South America in 2026 — Brazil, Argentina, Colombia

Something shifted in South America's travel scene over the past year or two. Visitor numbers are up — way up — in Brazil, Argentina, and Colombia especially. But the local SIM infrastructure hasn't kept pace. Airport kiosks are still a mess, staff rarely speak English, and the registration requirements for prepaid SIMs in Brazil in particular have gotten more complicated, not less. You now need a CPF (a Brazilian tax ID) to register a local SIM. If you don't have one, you're stuck.

That's exactly why eSIMs have gone from "nice to have" to "just sort it before you fly." You install one before you leave home, land in São Paulo or Bogotá, and your phone works. No queues. No paperwork. No fumbling with a SIM pin in an airport bathroom.

But not all eSIMs are equal — especially across a continent where network quality swings wildly between cities and rural areas. Here's what actually matters, and what we'd recommend.

What to Look for in a South America eSIM

Before we get into specific picks, let's talk about what separates a good eSIM from a frustrating one in this part of the world.

1. Regional coverage vs. country-specific

South America is enormous. A SIM that works brilliantly in Buenos Aires might go completely dark the moment you cross into Brazil. If you're visiting more than one country — and a lot of travellers do a Brazil-Argentina or Colombia-Brazil trip — you want a regional plan that covers the whole continent, not a per-country card you'll have to swap mid-trip.

2. Data caps that make sense for how you actually travel

Wi-Fi in South America is patchy at best. Hotels are hit and miss, cafés in smaller cities often have unusable speeds, and you'll be relying on your phone for maps, translation, and directions constantly. A 1GB plan sounds cheap until it's gone by Wednesday. Look for plans offering at least 5–10GB for a two-week trip, or an unlimited option if you're staying longer.

3. Network partners — this actually matters here

In Brazil, Claro and Vivo are the two networks worth being on. In Colombia, Claro and Movistar are solid. An eSIM that routes you onto a lesser local partner can mean patchy 3G in areas where decent 4G is available. Check the small print — good providers list their network partners upfront.

4. What happens to your streaming

This is the bit most eSIM guides skip, and it shouldn't be. Your local eSIM gives you South American data with a South American IP address. So your Netflix will switch to the local library (which may be missing shows from your home country), your BBC iPlayer will block you entirely, and if there's a Premier League or NBA game you want to watch, you might find it's not available in your new location. A VPN — specifically NordVPN — solves this. It runs alongside your eSIM and keeps your streaming acting like you're back home.

Our Top Pick: Pair Airalo with NordVPN

We're giving you two things here, not one, because they solve different problems. Your eSIM is your connection. Your VPN is what you do with it.

Airalo — The eSIM We'd Actually Buy

Airalo is the biggest eSIM marketplace in the world right now, and for South America specifically, it's genuinely the best starting point. Here's why: they offer both country-specific and regional "Latam" plans, their interface is dead simple, and installation takes about four minutes on any modern iPhone or Android.

Their South America regional eSIM covers Brazil, Argentina, Colombia, Chile, Peru, and more — so if your itinerary evolves (as South American trips often do), you're not scrambling. Plans start around $17 (about £13 / €15) for 3GB and go up to $55 (around £44 / €51) for 20GB. For most two-week trips, the 10GB plan at around $34 (about £27 / €31) hits the sweet spot.

Networks: In Brazil they partner primarily with Claro, which is exactly where you want to be. Colombia runs on Claro too. Argentina can be a bit patchier depending on region, but it's still the best eSIM option available to international travellers without a local ID.

The one honest downside: Airalo doesn't offer calls or SMS on most of their data-only plans. You'll use WhatsApp like everyone else in South America does, so this genuinely isn't a dealbreaker — but know it going in.

NordVPN — The Thing That Makes Your eSIM Actually Useful

NordVPN is what we'd recommend here, full stop. Not because it's the flashiest name in VPNs, but because it's the most consistently reliable one for unblocking streaming services across the UK, US, and Australia — which is exactly what you need when you're sitting in a Medellín apartment wondering why your normal Netflix is now showing entirely different content.

It works on up to 10 devices simultaneously, so your phone, tablet, and laptop are all covered with one subscription. The apps are genuinely easy to use — pick a server location, tap connect, done. You don't need to understand how it works.

Pricing sits at $3.99/month (about £3.15 / €3.70) on their two-year plan, which is the one worth getting. The monthly rolling plan is $12.99/month (about £10.25 / €12) which is fine if you only travel occasionally.

And yes — NordVPN runs perfectly over an Airalo eSIM. We've tested this. There's no conflict, no speed disaster. You'll notice a small slowdown (that's just physics — your traffic is taking a longer route), but for streaming HD content it's more than fast enough.

Three Alternatives Worth Knowing About

Holafly — Best for Unlimited Data

If you're spending a month in South America, posting content, doing video calls, or just can't be bothered tracking gigabytes, Holafly's unlimited plans are genuinely good. Prices vary by country: Brazil unlimited for 30 days runs around $79 (about £62 / €73). It's not cheap, but unlimited is unlimited, and their network partnerships in Brazil are solid (Vivo and Claro both).

The catch: Holafly plans are country-specific, not regional. So a multi-country trip means buying multiple plans or mixing providers.

Saily — Best Budget Option

Saily is a newer player (it's actually made by the Nord team, same people behind NordVPN), and their eSIM plans for South America are genuinely competitive on price. You'll find 5GB South America regional plans for around $12 (about £9.50 / €11). The app is clean, activation is fast, and if you're already an NordVPN subscriber the bundled experience is neat.

It's a great shout for shorter trips or if you'll mostly be in cities with decent Wi-Fi as backup.

Nomad — Best for Flexibility

Nomad operates more like a data top-up service — you buy a chunk of data, use it, buy more if needed. For South America they offer regional plans that work across most major countries. Plans start small (1GB for around $9 / about £7 / €8.30) and scale up. Good if your trip is unpredictable or you want to start small and see how much data you actually use.

Their app is slightly clunkier than Airalo's, but the coverage is comparable and their customer support is responsive.

Side-by-Side Comparison

The Verdict: Who Should Buy What

You're doing a classic South America trip — Brazil plus one or two other countries: Get the Airalo regional plan (10GB is probably right for two weeks) and add NordVPN. This combo covers your data and keeps your streaming working. Total outlay is around $38 (about £30 / €35) for the eSIM plus whatever NordVPN plan you're on. It's the setup we'd use ourselves.

You're spending a month or more in Brazil specifically: Holafly's unlimited Brazil plan is worth the premium. You won't think about data again. Still pair it with NordVPN.

You're on a tight budget and mostly staying in cities: Saily's regional plan at around $12 (about £9.50 / €11) is genuinely decent. Rely on café and hotel Wi-Fi for heavier use, and use the eSIM data for maps and messaging when you're out.

You don't know your exact itinerary yet: Start with Nomad's smaller plans and top up as you go. It's not the most cost-efficient approach if you use a lot of data, but it's the most flexible.

And whatever eSIM you pick — seriously, add NordVPN. South America is not the place you want to discover that your home streaming library has vanished.

Frequently Asked Questions

Do eSIMs work in Brazil without a CPF?

Yes — that's actually the whole point of using an international eSIM rather than a local Brazilian SIM. Local prepaid SIMs in Brazil now require CPF registration, which is essentially impossible for tourists to complete on arrival. eSIMs from providers like Airalo, Holafly, or Saily bypass this completely because you're not registering with a local carrier directly. You activate before you travel, and it just works when you land.

Will my phone support an eSIM in South America?

If you have an iPhone XS or newer, a Samsung Galaxy S20 or newer, or most flagship Android phones from the past four years, you're almost certainly fine. The one thing to check: is your phone unlocked? If you bought it directly from a carrier on a contract, it might be locked to that carrier's network. You'd need to get it unlocked before an international eSIM will work. Call your carrier — it's usually free once you're out of contract.

Can I use NordVPN on an eSIM data connection?

Completely, yes. NordVPN works over any internet connection — Wi-Fi, regular SIM data, or eSIM data. There's no difference from the VPN's perspective. Just install the NordVPN app on your phone, connect to a server in your home country, and your streaming services will think you're still there.

What's the data situation like in Colombia vs. Brazil vs. Argentina?

Colombia has genuinely improved a lot — Medellín and Bogotá have solid 4G coverage and even 5G in patches. Rural areas drop off fast, but for city
