  • System and method for interoperability in remote provisioning architectures for embedded universal integrated circuit cards
    Patent number: 11758385
    Abstract: A system is provided that allows profiles from multiple mobile network operators to be provisioned across multiple eUICCs from different eUICC manufacturers that may each utilize different provisioning methods. This is accomplished through the use of an abstraction layer with application programming interfaces (APIs) that enable SM-DP and SM-SR functionality for eUICCs from multiple eUICC manufacturers and for multiple MNO profiles.
    Type: Grant
