# How does a Kurosim eSIM work?

A Kurosim eSIM is built directly into your compatible device, so there's no need to insert a physical SIM card.

To activate your eSIM, simply scan the QR code or enter the activation details provided by Kurosim.

Once activated, your eSIM connects to a local mobile network just like a physical SIM card. The difference is that you can activate and switch data plans digitally without replacing your SIM card.

This makes Kurosim eSIM a convenient and flexible solution for international travel, allowing you to stay connected as soon as you arrive at your destination.
