Questions People Ask

The answers you need about your Buenos Aires eSIM

An eSIM is a SIM card in software, already sitting inside your phone. Rather than hunting for a shop at Buenos Aires airport, you scan a code at home and have data the second you land. Nothing to slot in, nothing to lose.

The payment goes through and the QR code hits your email, usually inside a few seconds. Install it straight away, or leave it in your inbox and set it up any time before the flight.

For most people heading to Buenos Aires, the Unlimited plan is the simple answer — maps, video calls home, photos uploaded, and no counting megabytes.

Yes. Coverage runs across the whole Argentina network, so other cities and regions are covered too, not only Buenos Aires and keep your current plan.

Yes. Data goes through the eSIM. Calls and texts still arrive on your physical SIM. Both run at once, nothing gets switched off.
