Buying a local Argentine SIM is slower and more friction than most travelers expect. Movistar, Claro, and Personal all require passport registration in person, and remote activation processes (uploading a passport photo plus a selfie holding the passport) frequently fail or take an hour-plus to resolve in store. At Ezeiza Airport only Personal Flow has a dedicated stand, and it's not always staffed; Claro and Movistar require a city-center store visit. The ETravelSim eSIM is installed at home, requires no documentation, and connects the moment you land — for most short trips, the time saved alone covers the price difference.
