5G connectivity on your smart ring or Meta’s future Ray-Bans? This eSIM solution smaller than a grain of rice makes it possible and could pave the way to an ‘app store’ of networks udinmwenefosa@gmail.com (Efosa Udinmwen) | amznusa.com

• Infineon’s OC1230 is less than 4mm^2, smaller than a grain of rice
• You can fit nearly 40 of them in one nano SIM, the smallest physical SIM card on the market
• Infineon says it could fit in wearables like smart glasses or rings

Infineon Technologies has unveiled the world’s smallest GSMA-compliant eSIM solution – with dimensions of just 1.8 x 1.6 x 0.4 mm, the OPTIGA Connect Consumer OC1230 is smaller than a grain of rice and reduces printed circuit board (PCB) space requirements.

For scale, it’s also 37 times smaller than the industry standard Nano SIM and 130 times smaller than a standard SIM.

The OC1230 supports remote SIM provisioning (RSP) and multiple-enabled profiles (MEP), allowing users to store and manage multiple network operator profiles remotely.

Ultra-compact eSIM technology

The company claims its eSIM is built on Infineon’s Integrity Guard 32 architecture and Arm v8 technology, delivering a 25% gain in power/performance ratio compared to existing eSIMs.

In addition to 5G connectivity, this ultra-compact chip could fit in wearables like smart watches, glasses or even rings, reduce energy consumption by up to 50%, and sustain the health of a device’s lithium battery over time.

If you’re yet to get in on the eSIM craze as a business smartphone user, I’d recommend it if you need to switch providers seamlessly on the move.
