Buenos Aires eSIM
82 Argentina plans · from $5.39
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.

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.
