Buenos Aires eSIM
82 Argentina plans · from $5.64
Buenos Aires is a late city spread across barrios that each feel like a different town, and the practical realities — which exchange rate applies today, which taxi app to use, whether that milonga starts at midnight or two — all live on your phone. A travel eSIM covers it from Ezeiza, an hour out of town on a motorway you do not want to negotiate blind.
Landing at Ezeiza & Aeroparque (EZE / AEP)
International flights land at Ezeiza, 45–60 minutes from the centre; Aeroparque handles domestic and regional routes and is ten minutes from Palermo. Check which one your connection uses — travellers regularly book a domestic leg assuming the same airport.

How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.
Which networks you'll be on in Buenos Aires
Siima eSIMs for Argentina ride Claro and Movistar. Claro has the broader national footprint including Patagonia and the north-west; Movistar is comparable across the capital.
Coverage around Buenos Aires
Subte and the buses
Station coverage is good across all six Subte lines. Tunnel coverage between stations is inconsistent on the older lines — Línea A in particular — so load your route before descending.
Palermo, Recoleta and San Telmo
Strong 4G across the neighbourhoods most visitors stay in, with 5G in much of Palermo. San Telmo's Sunday market gets congested enough to slow things at peak hours.
La Boca and the riverfront
Covered throughout Caminito and Puerto Madero. Worth having live maps in La Boca specifically — the tourist streets are a small area and the advice is to stay within them.
Tigre delta and the pampas
The train north to Tigre holds signal the whole way. Coverage on the delta itself is good on the main channels and thins on the smaller waterways.
How much data you need
A week in Buenos Aires runs 3–5 GB. If you are continuing to Iguazú, Mendoza or Patagonia, size for the whole route — one Argentina plan covers all of it.
