A new proof of concept demonstration made by Qualcomm and Vodafone revealed a working smartphone equipped with Smartphone Integrated SIM (iSIM) technology (via Neowin). The demonstration was made using a modified Samsung Galaxy Z Flip3 5G whose Snapdragon 888 chip has a built-in Qualcomm Secure Processing Unit. Unlike eSIM, which uses a separate chip, iSIM uses the phone’s own system chip.
