Understanding eSIM Technology

What Is an eSIM?

An eSIM, or embedded SIM, is a digital SIM that allows you to activate a cellular plan from a carrier without using a physical SIM card. Built into your device, it enables you to switch between different carriers and plans effortlessly.

eSIM technology functions by downloading carrier profiles directly onto your device. Here's how it works:

1. Compatibility Check: Ensure your device supports eSIM functionality.
2. Carrier Selection: Choose an eSIM provider offering services in Buenos Aires.
3. Profile Download: Scan a QR code or use an app to download the eSIM profile.
4. Activation: Follow prompts to activate the plan on your device.
