Does data work on the Subte (underground)?

On platforms and in stations you'll usually have signal, but data drops in the tunnels between stops. Download your route in Cómo Llego and any offline maps beforehand so you can navigate the network without interruption.

Can I use the same plan for a day trip to Tigre or Colonia?

For Tigre and anywhere in Argentina, yes, it's one national plan. Colonia is across the river in Uruguay, though, so it isn't covered; you'd need a separate Uruguay eSIM for that hop.

Good to know in Buenos Aires City

Signal is excellent citywide, but the deep Subte (metro) lines lose data between stations; download your route in Cómo Llego and pre-load podcasts before a long Línea D or E ride.

Best time to visit Buenos Aires City

Spring and autumn (September to November, March to May) are ideal, with mild days for walking; summer is hot and humid, and winter cool but comfortable.
