Will my eSIM work at Ezeiza airport on arrival?

Yes. Install and activate it over airport WiFi before you land, and you'll have data the moment you switch your phone on at Ezeiza (EZE) or Aeroparque (AEP) - no hunting for a SIM kiosk.

Is there mobile signal on the Subte underground?

Coverage in the tunnels is intermittent, though many stations now have WiFi. Download your Cómo Llego route or an offline map before descending, and you'll navigate the network without a live connection.

Good to know in Buenos Aires

Buenos Aires's Subte (metro) has patchy signal underground, so download your route before you tap in. Ride-hailing like Cabify and DiDi is legal and usually far cheaper than street taxis from Ezeiza.

Two simple ways to buy

Buenos Aires eSIM plans: unlimited, or by the GB.

Every Buenos Aires eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Buenos Aires — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Best value for lighter, shorter trips
Clear allowance — pay only for what you need

On the ground

Where you'll lean on data in Buenos Aires.

Palermo Soho

Cafés, boutiques and late-night bars where you'll lean on maps and ride-hailing to hop between Soho and Hollywood.

Recoleta

Cemetery visits and museum queues go smoother when you can pull up opening times and book skip-the-line entries online.

San Telmo

Sunday's Feria de San Telmo antiques market is a maze, so live maps and Mercado Pago QR payments keep you moving.

La Boca

Around colourful Caminito and La Bombonera you'll want data to summon a ride back rather than walking out.

The practical bit

Getting around Buenos Aires on your eSIM.

Apps you'll want online in Buenos Aires

SUBE— The city's tap-and-go transit card for Subte, buses and trains; the app tops up your balance.
Cómo Llego— Buenos Aires's official journey planner for the fastest bus, Subte or walking route across town.
Cabify— Widely used ride-hailing app; book cars citywide and pay in-app, often cheaper than street taxis.
Mercado Pago— Argentina's everyday payment super-app - pay by QR in shops, cafés and markets like San Telmo.

How long to stay in Buenos Aires

Most visitors spend three to four days in Buenos Aires, enough for the classic neighbourhoods, a tango show and a day trip to Tigre or Colonia.

How much data for Buenos Aires

For a few days of maps, ride-hailing, translation and social posts, 3-5 GB is comfortable; choose Unlimited if you'll stream, hotspot a laptop or video-call home from your Palermo rental.

Coverage in Buenos Aires

Buenos Aires has strong 4G citywide and growing 5G in central barrios, carried by Claro, Movistar and Personal; expect signal to drop in Subte tunnels and soften in some far-out suburbs.

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
