How do you choose the best eSIM for South America?

Start with four things: how many countries you are visiting, how many days you are traveling, how much data you use, and whether the provider can actually hold a connection where you are going.

Price matters, but a cheap plan that drops signal in the Andes or on a long bus route is not a deal. Here is what to weigh, in order.

How many countries are on your route

If your trip touches more than one country, a regional Latin America eSIM that covers your whole route is cheaper and simpler than buying a separate eSIM in each place.

Confirm the total number of days up front so you size your eSIM South America plan correctly from the start, rather than paying again or topping up mid-trip.

Operator or reseller, and why it matters when something breaks

Some eSIM providers are mobile operators and some are resellers. An operator manages the network connection directly and can often fix an issue on the spot.

A reseller depends on a third-party network, so resolving a problem usually means more steps and more waiting.

GigSky runs as a mobile operator, which is also why your phone connects to the strongest local network on its own and why support can respond faster while you are abroad.

Airalo, Holafly, and Saily operate as resellers.

Fixed data or unlimited

If you use your phone for the basics while traveling, a fixed plan usually saves money. When choosing the best eSIM for South America, look for a fixed data plan that lets you pick your gigabytes and use them however you like.

Unlimited plans are for people who would rather not track usage at all: you choose the days, get your data, and skip the math.

Most travelers using maps, translation, WhatsApp, and a bit of social media land between 500MB and 1GB a day.

If you stream music or video, you will pass 1GB a day, and that is where unlimited earns its price.

For unlimited plans, check the throttling policy

Every eSIM provider that offers unlimited data has a throttling policy, which is the point where your high-speed data slows down.

Unlimited means you keep a connection for all the days in your eSIM South America plan, but full speed only runs up to that daily threshold, after which data continues more slowly.

The catch is that some providers disclose this clearly and some do not, and the disclosure itself tells you something.

GigSky lists its throttling policy at 3.5GB per day, so you know where full speed ends.

Holafly offers unlimited-only plans but does not disclose its throttling policy, so you are buying without knowing where your speeds ease off. That's worth factoring in if you plan to lean on unlimited data heavily.

Trip length

For a short trip, a travel eSIM is plenty. If you are traveling for more than about three weeks, an eSIM subscription usually costs less and keeps you connected across most South American countries.

GigSky, Saily and Holafly offer a monthly subscription spanning multiple countries in South America, which suits longer or back-to-back trips.

If a longer trip continues into Mexico or Central America, check whether an eSIM Latin America​ plan covers the full route.

Whether you can test it first

A few providers let you try an eSIM at no cost before you buy, which is a low-risk way to confirm coverage in your destination.

Prices and country counts reflect the regional South America plans available at the time of writing. Check each provider's app or site for the exact countries before you buy, since coverage lists change and a Latin America​ eSIM can include a different mix of countries.

A closer look at each provider

GigSky

GigSky is a single regional eSIM covering 16 South American countries, and it’s the most affordable option here for unlimited data.

You install it once, and it connects automatically when you arrive, with no QR codes and no settings to change on landing.

As a mobile operator, it partners directly with local networks so your phone latches onto the strongest one available, and it can respond faster if something goes wrong mid-trip.

The honest tradeoff: its fixed-plan entry price sits above Airalo's, so if you only care about the cheapest set data bundle, Airalo will usually cost less. GigSky's case rests on wider coverage, free eSIM trials, automatic connection, and the operator model.

Airalo

Airalo covers 17 countries and posts the lowest prices on fixed data bundles in this group, which is why budget-conscious travelers comparing eSIM South America plans gravitate to it.

You set up a plan per trip, usually in under five minutes, with QR-based or manual install options, then activate it yourself on arrival.

The main feature to watch is validity: those cheap fixed bundles run 7 days, shorter than other alternatives, so a longer trip may need more than one.

Holafly

Holafly covers 18 countries and sells unlimited data only, so there is no allowance to track.

You pick the number of days and get unlimited data for that window, which suits heavier browsers and streamers.

One point to weigh before buying: Holafly does not disclose its throttling policy, so you will not know in advance where your high-speed data slows down.

For light users who mostly need maps and messaging, a fixed plan elsewhere may be the simpler value.

Saily

Saily covers 12 countries with fixed data plans only and positions itself around security and privacy.

You pick a fixed amount and use it across the covered countries over a 30-day validity.

Its 10GB plan is the lowest-priced 10GB option in this group, and the long validity gives room on a slower-paced trip. There is no unlimited tier, so it is a straight fixed-data choice.

How to set up a South America eSIM the right way

Do these before your trip so you land connected and avoid paying for an eSIM South America plan you cannot use.

1. Dial *#06# on your phone. If an EID number appears, your phone is eSIM-compatible.
2. Confirm your phone is unlocked. On an iPhone, open Settings, then General, then About, and scroll to Carrier Lock. If it reads No SIM restrictions, you are unlocked. If it reads anything else, contact your carrier to unlock it. For a full walkthrough on checking if your phone is unlocked, GigSky has a guide here.
3. Turn off your physical SIM if you want to avoid roaming charges, since leaving it on can trigger them while the eSIM handles your data.
4. Install a free trial where available. GigSky offers up to 10GB free for eligible Visa cardholders from the Americas through a Visa benefit in the GigSky app, so you can test coverage before paying.

Set up the eSIM the night before or the morning of your trip while you are still at home.

What is the best eSIM for traveling in South America?

Airalo has low fixed-plan prices. Holafly focuses on unlimited-only plans, though its throttling policy isn't disclosed. Saily offers fixed-data plans with a privacy focus.

Do I need a different eSIM for each country in South America?

No. A regional eSIM covers multiple countries on one plan, which is cheaper and simpler than buying a separate eSIM per country. An eSIM Latin America​ plan works the same way if your trip reaches beyond South America.

How much data do I actually need for a trip?
