What Is an eSIM and How Does It Work?

An eSIM is a digital SIM profile that can be installed onto compatible devices without inserting a physical card.

For travel, that makes remote delivery and setup possible before departure.

The traveler receives a QR code or install link, adds the profile on Wi-Fi, then activates data during the trip.

The exact menu labels vary by device, but the flow is broadly similar across major platforms.
