How to Set Up an eSIM in Argentina 2026: iPhone & Android

Here is how to set up eSIM in Argentina: buy a data plan, install it over Wi-Fi before you fly, then switch on Data Roaming for that line when you land at Ezeiza or Aeroparque. The whole process takes a few minutes on a recent iPhone or Android phone, and this guide walks through every screen, the settings that trip people up, and what to do if the bars appear but nothing loads.

Before You Start: Check Your Phone and Pick an Argentina eSIM Plan

Two things decide whether your Argentina eSIM setup goes smoothly: a phone that supports eSIM and is carrier-unlocked, and a plan sized for your trip. Get both right at home and the rest is a handful of taps.

Is your phone eSIM-ready?

Our plans work on iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many other recent eSIM-enabled models. The phone must also be carrier-unlocked. A handset bought on contract from a home network can be locked to that network, and a locked phone will usually refuse a second provider's eSIM. A quick check: dial *#06#. If an EID number appears, the hardware supports eSIM. Unlock status is a separate question, so ask your home network if you are unsure. Our FAQs carry the full device list.

Which plan should you buy?

Our Argentina catalogue has 12 plans, from 100 MB up to 20 GB. The table below shows the ones that fit most trips. Prices are in USD as of October 2026; confirm the figure on the product page at checkout.

My pick for a 10-day trip: buy the 3 GB / 15 days plan rather than the 1 GB / 7 days, because the week-long plan simply expires before you fly home and you end up paying for a top-up anyway. If you want the full sizing logic, our Argentina eSIM plan sizing guide covers every tier.

How to Install an eSIM on iPhone for Argentina

On iPhone, the install takes about two minutes and you should do it at home, on Wi-Fi, the day before you fly. After checkout, Latam Travellers emails a QR code, an "Install on iPhone" button and manual activation details. Any one of the three works, and each can only be used once.

Option A: the one-tap install button

Open the delivery email on the iPhone itself and tap Install on iPhone. iOS opens its eSIM setup screen directly. Tap Continue, wait for the plan to download, then label the new line something obvious, such as "Argentina". This route suits travellers who only have one device to hand.

Option B: scan the QR code

1. Display the QR code on a laptop, tablet or printout (you cannot scan a code on the same screen you are using).
2. On the iPhone, open Settings and tap Mobile Service (called Cellular or Mobile Data depending on region and iOS version).
3. Tap Add eSIM (shown as Add Cellular Plan on some versions), then Use QR Code.
4. Scan the code and follow the prompts. When asked, label the line "Argentina".
5. When iOS asks which line to use for data, you can leave your home line selected for now. You will switch it on landing.

Apple's own Set up eSIM on iPhone guide shows the same screens with screenshots if you want a visual reference.

Check that it worked

Go back to Settings, then Mobile Service. You should now see two lines. The new one may say "Activating" or appear inactive until you reach Argentina. That is normal: the plan has not started and no data is being used. If you can see the line listed, you are done until you land.

How to Install an eSIM on Android (Samsung and Pixel)

Android setup follows the same logic as iPhone, but the menu names differ by brand and Android version. Scan the QR code from another screen, and do it on Wi-Fi before you travel.

Samsung Galaxy

1. Open Settings, then Connections, then SIM manager.
2. Tap Add eSIM, then Scan QR code.
3. Scan the code from your delivery email and confirm.
4. Give the eSIM a recognisable name, such as "Argentina", and leave it switched on.

Google Pixel

1. Open Settings, then Network & internet, then SIMs.
2. Tap Add SIM (or the plus icon). If prompted about inserting a SIM, choose the option to download an eSIM instead.
3. Scan the QR code and follow the prompts to finish.

Google's Pixel dual-SIM help page explains how to choose which SIM handles data, which you will need on arrival. If your phone cannot scan a code, enter the manual activation details from the same email instead.

What to Do When You Land in Argentina

The single setting that matters on arrival is Data Roaming, switched on for the eSIM line and off for your home line. Our plans connect to local Argentine networks as a roaming service, so with roaming off the eSIM shows bars but passes no data.

Step five is the one people skip. With data switching on, the phone can quietly fall back to your home line when the eSIM signal dips, and your home network may bill roaming for it. Keep your home SIM active anyway, so bank verification texts still reach you.

Bars showing, nothing loading?

First, toggle airplane mode on and off and give the phone a minute. Second, confirm Data Roaming is on for the eSIM line specifically. If your delivery email names a network, select it manually under network selection. If it does not, reply to that email and our support team will tell you which network to choose. Do not hop to a different network just because it shows full bars, as an off-plan network can display signal and still pass zero data.

Above all, never delete the eSIM while troubleshooting. Each code works once, and a deleted eSIM usually cannot be reinstalled. Message us instead; we can almost always fix it or replace it.

Using Your Argentina eSIM Day to Day

Once connected, the eSIM behaves like any mobile data line, with a few habits worth knowing. The plans are data-only, so there is no Argentine phone number. WhatsApp, which is the default way to message restaurants, tour operators and hosts across Argentina, works normally over data, as do WhatsApp calls, FaceTime and iMessage.

Coverage on Argentine networks is typically strong across Buenos Aires, Córdoba, Rosario, Mendoza and Bariloche. It thins out on long Patagonian drives and in remote parts of the Northwest, where every provider's signal drops, so download offline maps before road trips. Our Patagonia eSIM guide covers those stretches in detail, and the Buenos Aires eSIM guide covers airport arrival and cafe Wi-Fi in the capital.

Tracking usage and topping up

Your phone's mobile data screen shows usage per line, and you can look up your plan on our My eSIMs page. Both can lag by two to three hours. If you run low, a top-up adds data to the same eSIM and extends its validity, with no new QR code to scan. For a feel of how fast maps, ride-hailing and video eat data, see our South America data usage breakdown.

Crossing into Uruguay or Chile

The Argentina plan is single-country. If your route includes the ferry to Montevideo or a Patagonian border crossing, install a separate Uruguay eSIM or Chile eSIM before you go and switch the data line at the border. Phones can hold several eSIMs at once, so this is a settings change, not a reinstall.

If you are still shaping the route, Meili, our free AI travel planner, turns your travel month, trip length, pace and priorities into an editable day-by-day itinerary. For entry rules and safety updates, check the UK FCDO Argentina travel advice and the Argentina government tourism portal. Conditions can change, so check your own government's advisories before travelling.

Why Set Up an eSIM Instead of Buying a SIM at the Airport?

The real advantage is timing: an eSIM installed at home works the moment you walk off the plane. A physical SIM means finding a kiosk after a long-haul flight, possibly showing your passport for registration, and swapping out your home SIM, which takes your usual number offline. With an eSIM you keep both lines, order your ride from arrivals, and message your accommodation before you clear the terminal.

A local SIM can still make sense for long stays where an Argentine number matters. For a trip of a few weeks, the eSIM route is simpler. We focus exclusively on Latin America connectivity, and our Argentina eSIM quick answer compares the options if you are still choosing a provider, and the Latin America activation walkthrough applies the same steps to other countries on your route.

Frequently Asked Questions

Can I install my Argentina eSIM before I leave home?

Yes. Installing at home on Wi-Fi is the recommended approach. Your plan's days only start when the eSIM first connects to a network in Argentina, not when you buy or install it.

Do I need to turn on Data Roaming in Argentina?

Yes, for the eSIM line only. The plan works as a roaming service on local networks, so Data Roaming must be on for the eSIM. Keep it off on your home line to avoid charges from your home network.

Will I get an Argentine phone number?

No. The plans are data-only, with no phone number, calls or SMS. WhatsApp, FaceTime and other app-based calls and messages work normally over the data connection.

Can I reinstall the eSIM if I delete it by mistake?

Usually not. Each QR code and activation code works once, and a deleted eSIM generally cannot be reinstalled. Never delete it while troubleshooting; contact support from your delivery email instead.

Does the Argentina eSIM work in Uruguay or Chile?

No. It is a single-country plan for Argentina. Install a separate Uruguay or Chile eSIM before you travel and switch your data line at the border.

Can I add more data if I run out?

Yes. A top-up adds data to the same eSIM and extends its validity, with no new QR code. Top-ups apply to a plan that is still active rather than one that has already expired.

Setting up an eSIM for Argentina comes down to three moves: install at home on Wi-Fi, switch Data Roaming on for the eSIM when you land, and keep your home line from roaming. Latam Travellers emails the QR code within minutes of checkout. Our Argentina trip cost guide covers the rest of the budget, and all our Latin America plans are in one place if Argentina is one stop of several.
