一种eSIM预置种子码号的方法
By applying for unified KI and OPC number resources from multiple operators and dynamically modifying the IMSI in eUICC, the problem of high complexity and high cost of managing pre-set seed numbers for eSIM is solved, realizing the sharing and reuse of numbers and the flexibility and security of devices.

AI Technical Summary
In existing technologies, the method of pre-setting seed codes in eSIM results in high complexity and cost of code management, and the code codes cannot be changed. In addition, the seed code code corresponds one-to-one with the device IMEI, and cannot be adjusted according to changes in needs or environment.
By applying for code resources from multiple operators, pre-setting an eUICC profile with an invalid IMSI that has a unified KI and OPC, the control program randomly selects and modifies the IMSI, dynamically writes the appropriate operator code, and combines fault detection and validity checks to ensure security and flexibility.
It enables the sharing and reuse of seed codes, reduces resource costs, improves the flexibility and reliability of device network connections, and ensures data security and product versatility.
