Infineon Technologies has introduced the world’s smallest GSMA-compliant eSIM solution, the OPTIGA Connect Consumer OC1230. This tiny chip, measuring just 1.8 x 1.6 x 0.4 mm, is smaller than a grain of rice and significantly reduces PCB space requirements. For comparison, it’s 37 times smaller than a Nano SIM and 130 times smaller than a standard SIM card. The OC1230 supports remote SIM provisioning (RSP) and multiple-enabled profiles (MEP), enabling users to manage multiple network operator profiles remotely.
Built on Infineon’s Integrity Guard 32 architecture and Arm v8 technology, this ultra-compact eSIM delivers a 25% improvement in power/performance ratio compared to existing eSIMs. It not only supports 5G connectivity but also opens up possibilities for integration into wearables like smart glasses, rings, or watches. This chip can reduce energy consumption by up to 50% and help maintain the overall health of a device’s lithium battery over time. Businesses looking for seamless provider switching on the go should consider adopting eSIM technology.
