The eSIM specification enables remote SIM provisioning without the need to hand out a physical SIM card. Instead of a physical SIM card, the subscriber downloads a SIM profile, which contains a subscriber's identity and authentication key material, to their embedded UICC, a discrete, embedded chip in the user's phone. This provisioning process is specified in the remote SIM provisioning (RSP) protocol and is secured through contemporary public-key cryptography. However, the potential advent of g
