eSIM for global IoT connectivity

ST4SIM-300 is ST’s first eSIM based on GSMA eSIM for IoT specification. By integrating this product into their design, IoT developers can now enable the best connectivity anywhere, at any time.


ST4SIM-300 offers new possibilities, such as over-the-air profile swaps. The solution comes with a simplified ecosystem, and is ideally suited for small devices without a user interface. It supports constrained networks, such as NB-IoT.
