5G connectivity in your smart ring or future goal rays? This eSIM solution smaller than a grain of rice makes it possible and could pave the way to an ‘app store’ of networks




  • Infineon’s OC1230 is less than 4 mm^2, smaller than a rice grain
  • You can place almost 40 of them in a Nano Sim, the smallest physical sim card
  • Infineon says that it could fit in wearables such as glasses or smart rings

Infineon Technologies has presented the smallest ESIM solution that meets GSMA, with dimensions of only 1.8 x 1.6 x 0.4 mm, the Connect consumer OC1230 is smaller than a grain of rice and reduces the space requirements of the printed circuit plate space (PCB).

For the scale, it is also 37 times smaller than the standard Nano Sim of the industry and 130 times smaller than a standard SIM.
