Is it rude to not speak Spanish in Buenos Aires?

Not at all. Locals are generally helpful. Just start your interactions with 'Hola' and 'Gracias', and most will be patient if you use translation apps.

Should I take taxis off the street?

Stick to apps like Uber or Cabify. Street taxis require you to communicate with the driver about routes and often require cash, which adds unnecessary friction if you don't speak the language.

Will my credit card work for transport?

No. You must have a physical SUBE card to use buses and subways. You can top these up with cash at kiosks or subway stations.

Getting Around Buenos Aires Without Speaking Spanish

You can navigate Buenos Aires entirely using ride-sharing apps like Uber or Cabify and by downloading an offline map of the city. While knowing a few Spanish phrases helps, sticking to digital tools and tourist-friendly neighborhoods allows you to move freely without a language barrier.

Download the essential apps. Install Uber and Cabify before you leave home. In Buenos Aires, these are safer and more reliable than hailing street taxis, as the price is fixed in the app, eliminating the need for language-heavy negotiation.
Master the SUBE card for subways. Buy a SUBE card at a 'Kiosco' (small corner shop) marked with a SUBE sign. You cannot pay cash on public transit; you must tap the card. You can use Google Translate to show the clerk 'Una tarjeta SUBE, por favor'.
Use offline maps. Download the Buenos Aires area in Google Maps for offline use. This prevents you from needing to ask for directions if your mobile data signal drops in older, thick-walled buildings.
Navigate the subte (subway) by color. The subway system is color-coded. Memorize the color and the last station name of the line you need. If you get confused, show your destination on your phone to a station agent; they are used to international travelers.
