Connectivity tailored to your device.

We interviewed the industry's top leaders and found that the single biggest barrier to connectivity was the limitation of SIM technology. In short, no single technology offered the capability that product innovators required, so we assembled a stack of SIM technologies that include a proprietary SIM profile and out-of-the-box bootstrap capabilities. We call it Io3 SIM.

Three forms. One platform. Limitless possibilities.

The Io3 SIM stack is based on the latest GSMA eSIM / eUICC technology. What does that mean in people speak? It means the ability to remotely provision and reprogram on the fly. Or in other words, the power to choose the best provider at any time. No paper clip required.
