What is an eSIM card?

An eSIM (embedded SIM) is a SIM card in the form of a small chip that is built directly into the motherboard of a phone, smartwatch, or other device by the manufacturer. Unlike a physical SIM card, an eSIM profile is downloaded to the device remotely via an internet connection, for example by scanning a QR code, using a link, or through your mobile operator’s app.

A single eSIM chip can store multiple operator profiles, for example, for your work and personal numbers or a mobile plan for travelling abroad. You can easily switch between these profiles in your device settings. However, not all downloaded profiles can be active at the same time.
