More Flexibility for the Connected Value Chain

By enabling eSIM and iSIM, Kigen OS helps to overcome the barriers of the traditional SIM model.


eSIM (eUICC) and iSIM are poised to radically change the connected value chain by bringing a lot more flexibility to the way SIMs are procured and managed. Now different stakeholders can have supply relationships for each aspect of a SIM product and, as these new technologies continue to mature, we expect to see new business models, services and fundamentally different interactions within the connected value chain.
