Introduction
With ever-accelerating deployment of the cellular Internet of Things (IoT) and other connected devices, it’s becoming apparent that there’s a growing need for security. The most well established is found in smartphones — the familiar SIM, or the standard subscriber identity module. SIMs need to be replaced with something that’s smaller, more versatile, and more efficient, or even dematerialized for the end user, while maintaining the identity and security levels that SIMs provide. As IoT devices begin to fulfill more and more functions in smaller packages, ensuring seamless connectivity, saving space, and reducing power consumption are becoming even more critical parts of the design process. As those devices become ever more
ubiquitous and present across the globe, there is a growing need to keep the devices and their data securely managed in field in a scalable manner economically. eSIM and iSIM evolve SIM technology to achieve this affordably and open the benefits of global, secure connectivity without the need for prior expertise in cellular.
About This Book
eSIM & iSIM For Dummies, Kigen 2nd Special Edition, introduces you to embedded SIMs (eSIMs) and integrated SIMs (iSIMs), two new form factors of SIM that provide all the advantages of traditional SIMs while offering enhanced physical security, lower power consumption, reduced size, and remote provisioning capabilities. In addition, this book shows you that eSIMs and iSIMs offer the promise of cost savings in handling, activation, and keeping
connnected — the total cost of ownership (TCO) associated with the billions spent on handling SIMs
