However, like many aspects of cellular technology, the knowledge of the technology behind it is not widely understood. - despite its ferquent use by a large user base. This talk aims to change that, as far as possible in a 45minutes introductory talk. Aspects covered are: * What is an eSIM? * The eUICC as physical "trusted chip" inside the phone * The 3 flavors of eSIM: Consumer, M2M and IoT * The eSIM cryptographic chain of trust * The invovled network elements, their purpose, procedures (SM-DP+, SM-SR, LPA/IPA, ...) The talk is a technical talk, and is held in the expectation is that the audience has some basic understanding of networking, cryptography and SIM card technology.
