eSIM stands for Embedded SIM. While a traditional physical SIM card is inserted into a device, an eSIM is embedded in the device and does not need to be inserted or removed. Simply sign up for a communication plan through an app or website provided by the service provider, and the plan is instantly available.

This provides greater flexibility, enhanced security, and seamless device activation compared to traditional SIM cards. Currently, eSIM is attracting attention from telecommunications carriers around the world and is regarded as a revolutionary technology that will overturn traditional means of communication.
