Since the profile of the mobile communication operator can be written to the UICC via the communication line (mobile line) of the mobile communication operator by OTA (Over The Air) after manufacturing, the mobile communication operator's profile can be written to the UICC. There is no need for user replacement when switching operators. Non-Patent Documents 1 and 2 disclose that a profile is downloaded from SM (Subscription Manager) -DP (Data Preparation) + by the LPA (Local Profile Assistant) function in the device (communication terminal) and stored in eUICC. ing.

By the way, obliging mobile communication carriers to verify their identity at the time of contract and transfer of mobile phones, and punishing the act of lending mobile phones for a fee without confirming the other party's nomination and contact information. In 2005, a law was enacted as the Mobile Phone Unauthorized Use Prevention Law, which aims to eliminate the generation and distribution of phone numbers that cannot identify the contractor and prevent the use of mobile phones for crimes such as transfer fraud. Has been done. As a result, when an individual makes a voice communication (call) contract with a mobile communication operator using the communication line of the mobile communication operator in Japan, identity verification is obligatory, and this is essential. there were. On the other hand, when an individual makes a data communication contract with the mobile communication operator using the communication line of the mobile communication operator, identity verification is not necessary.
