Introduction to eSIM

eSIM (Embedded Subscriber Identity Module) is a virtual SIM card technology built into devices. Unlike traditional physical SIM cards, it does not require actual insertion or replacement of card slots. eSIM is integrated into the chip and can be configured and activated through software, enabling users to easily switch mobile network operators or add multiple virtual operator profiles.

eSIM technology allows device manufacturers to provide connectivity services in a more flexible manner, while bringing convenience and a seamless connection experience to users. Users can directly configure eSIM through their devices or applications and select suitable mobile network operators or data plans.

eSIM is widely used in smartphones, tablets, smartwatches and other connected devices, providing users with a more convenient, flexible and customizable mobile communication solution.
