The validity timer on the ETravelSim Argentina eSIM starts the day you begin using it in Argentina, not when you buy or install it. You can purchase weeks in advance, install the QR code at home before flying, and the 7- or 30-day countdown only begins once your phone connects to Movistar on arrival. Installing at home is the safer option — you'll know before boarding that the eSIM is set up correctly. After installation, don't delete the eSIM profile from your phone; reinstallation may not be possible.
