eSIM or a local SIM at the airport in Argentina?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Argentina starts at $19.87 on this page, which is hard for airport kiosks to beat.

Setting up your Argentina eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Argentina
Argentine law requires every SIM to be registered with your passport at purchase.
At Ezeiza the only official stand is Personal Flow, near check-in counter 40, where staff register your passport and activate the SIM before you leave the terminal. The stand usually takes cards only, no cash.
For Patagonia, Claro is the clear winner and keeps signal in places like El Chalten and Puerto Madryn where Personal drops out. All three networks work well within Buenos Aires city.
