The Difference Between eSIM and Traditional SIM

A traditional SIM is a small plastic card capable of storing subscriber information such as names, phone numbers, and user authentication details. It represents the first generation of SIM technology, consisting of a plastic body and a copper core with an embedded microchip that stores data.

In contrast, an eSIM is a digital SIM that replaces the need for a physical card. It is soldered directly into the device’s circuitry, making it more compact while still offering full functionality. With eSIM, customers can switch carriers through software without the hassle of physically removing or replacing the card

Each QR code acts as a unique activation key that can be scanned only once, linking the eSIM profile permanently to the device used during the first installation. After activation, the QR code becomes invalid and cannot be reused under any circumstances — not even on the same device after a factory reset, software update, data wipe, or accidental deletion of the eSIM profile.
