What if a small eSIM could cut energy use by 50%, extend battery life, and eliminate physical SIM cards? See how this change could affect device design and connectivity.

The demand for more functionality, simplicity, and longer battery life in wearables, smartphones, and tablets continues to rise, especially in the consumer sector. Infineon Technologies AG addresses these needs with the OPTIGA Connect Consumer OC1230 launch, the world’s smallest GSMA-compliant 28 nm eSIM solution.
This eSIM reduces energy consumption by up to 50% compared to other market solutions, significantly extending device battery life without sacrificing performance. Its remote management capabilities eliminate the need for physical SIM changes, saving time and resources while enhancing flexibility. Smartphone users can easily switch between providers, and manufacturers gain more design freedom by removing the need for physical SIM slots. This is especially advantageous for IoT devices.
The OPTIGA Connect Consumer OC1230 suits smartphones, tablets, notebooks, smart watches, wearables, 5G routers, and POS terminals. It benefits mobile network operators. Businesses and IoT developers can use its connectivity for IoT applications such as smart home devices, connected healthcare, and industrial solutions, improving connectivity, design, and battery life.
The eSIM’s advanced security architecture is based on Arm® v8 and Infineon’s Integrity Guard 32 technology, improving the power-to-performance ratio by 25%. It supports GSMA-compliant Remote SIM Provisioning (RSP) and Multiple Enabled Profiles (MEP), allowing users to download and activate multiple network profiles remotely.
With a compact size of just 1.8 x 1.6 x 0.4 mm, the chip-scale packaging reduces PCB space requirements by 37 compared to Nano SIMs and 130 compared to standard SIMs. An alternative X2QFN20 package (3.0 x 3.0 x 0.3 mm) is also available. The eSIM’s 1 MB memory accommodates multiple operator profiles, applications, and user data, making it a powerful and space-efficient solution for modern consumer devices.
