A Subscriber Identity Module (SIM) is a small, removable card that serves as a fundamental component in mobile telecommunications. Placed within a mobile device, the SIM card securely stores key information, including the International Mobile Subscriber Identity (IMSI) and authentication key, enabling the device to connect to a mobile network. The SIM card associates the user with the mobile network, allowing for voice and data services, and facilitates secure authentication during the network registration process. SIM cards can store contact information, text messages, and other user-specific data. SIM cards come in various forms, including traditional credit-card-sized SIMs, mini-SIMs, micro-SIMs, and nano-SIMs, catering to the evolving design requirements of mobile devices. The portability of the SIM card allows users to easily switch devices while retaining their subscriber information, contributing to the flexibility and convenience of mobile communication.

The Scheme GCS, Group C for Subscriber Identity Module, is crucial in mobile networks, providing a secure and portable way to identify and authenticate mobile subscribers. This scheme establishes standardized specifications for the design and interoperability of SIM cards, essential components in mobile devices. Compliance with Group C ensures that SIM cards consistently meet performance standards, facilitating reliable and secure mobile communication. Adherence to this scheme supports the creation of a standardized and interoperable environment for SIM cards, ensuring their compatibility and reliability across various mobile devices in the dynamic landscape of mobile telecommunications. The GCS Scheme, Group C, is vital for advancing the overall security and functionality of SIM cards in mobile networks.

Note: Manufacturers of SIM are required to obtain the mandatory TEC Certification to sell their products in the Indian market.
