what is e sim

An eSIM is a form of SIM card that is embedded directly into a device. Instead of an integrated circuit located on a removable SIM card, typically made of PVC, an eSIM consists of software installed onto an eUICC chip permanently attached to a mobile device at the factory. The eUICC chip used to host the eSIM uses the same electrical interface as a physical SIM as defined in ISO/IEC 7816 but with a small format of 6 mm × 5 mm. An eSIM is a virtualized SIM card profile installed onto an eUICC chip permanently surface-mounted to a mobile device at the factory. It performs the same function as a traditional SIM card but has the potential to make things a lot simpler for most smartphone users. An eSIM is an industry-standard digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM. It contains the personal information (such as the telephone number) and the configuration that connects the cellphone to the cellular network of a given company to link the user to the operator providing and managing the selected cellular services. An eSIM is sometimes called by its technical name, eUICC (Embedded Universal Circuit Card) or virtual SIM.
