Vodafone, Qualcomm and Thales announced that they have successfully completed iSIM technology trials that could pave the way for more devices to be connected to and managed by mobile networks. Traditionally, a SIM card is required to connect to a cellular network, and when a change is made to the network, it is necessary to change the SIM card as well.
What is the Difference from eSIM?
Software-based eSIM technology combines the functionality of SIM cards with the flexibility of software and allows users to remotely switch operators, switch to new service models and use more flexible designs in mobile phones.
Thanks to the eSIM, things are changing for the SIM card, a component that has remained untouched in mobile phones for ten years. In fact, it does not completely disappear, because eSIMs require a special processor and system resources to work. In other words, this processor comes instead of the SIM card.
The next step of this technology, iSIM, can be integrated directly into the processor of the mobile phone and there is no need for a separate chip. Thus, the section previously reserved for the SIM card slot can be used to add a larger battery.
“Our aim is to create a world where every device is seamlessly and simply interconnected and where the customer has full control,” says Alex Froment-Curtil, a Vodafone executive. It connects to many objects by allowing it to be connected without a SIM or special chip. This is a very important development, especially for the world of IoT.”
