eSIM (Embedded SIM) is a digital version of a physical SIM card, pre-embedded in devices like smartphones, tablets, and smartwatches. It can be programmed remotely, allowing users to switch between different telecommunication services without needing a physical SIM card. eSIMs are particularly useful for roaming and in devices requiring multiple communication providers, including IoT devices.
eSIMs are versatile and find applications in various devices and scenarios due to their flexible and remotely controllable nature.
eSIMs are increasingly adopted in smartphones and tablets, enabling users to switch carriers easily and facilitating international roaming without needing new SIM cards.
Wearable devices like smartwatches benefit from eSIMs, offering independent communication capabilities and enhancing user convenience.
Mobile notebook PCs are integrating eSIMs to eliminate the need for microSIM slots, contributing to a more compact and lightweight design.
eSIMs are used in in-vehicle systems for real-time navigation and entertainment services, as well as for remote vehicle management and emergency communication.
In IoT devices, eSIMs facilitate efficient management and allow the flexibility to switch communication providers as needed.
An eSIM functions similarly to a nano-SIM but is directly mounted on the motherboard of a device. Each eSIM has a unique ID used for authentication and contract management. Network operators can remotely control the eSIM's profile via OTA (Over the air), enabling users to easily switch carriers.
eSIMs are categorized into M2M and consumer models.
The M2M model is designed for embedding in IoT devices, optimized for communication with specific servers, and simplified for limited functionality.
The consumer model is intended for devices operated by end-users, providing full operational control from the user's terminal.
eSIMs differ from traditional SIM cards in form, usage, and user benefits. Unlike physical SIM cards, eSIMs are integrated into devices, allowing users to switch communication providers remotely without needing to replace the SIM card.
