Do I Need an eSIM for Argentina?

Argentina has decent networks (Claro, Personal, Movistar), but:

• International roaming is expensive — $10-20/day
• Local SIM registration requires a DNI or passport and can be bureaucratic
• Argentina's economic situation means local SIM availability and pricing fluctuates
• Patagonia trips need data for navigation in remote areas
• Buenos Aires requires ride apps (Uber, Cabify) for safe transport

An eSIM avoids all the local hassle. Buy before you fly and connect instantly.
