Everything You Need To Know About eUICC Powered SIMs/eSIMs
A ConnectedYou SIM allows a user to decide & change the Connectivity Providers on the physical SIM.
This decouples the SIM hardware from connectivity the Connectivity Provider provides giving the user the benefit of always being in control of their connectivity ecosystem.
eUICC functionality
The ConnectedYou SIM is built using standard & industry approved eUICC functionality to manage Connectivity Providers on the SIM with GSMA endorsed security guidelines. The following is the reference for the GSMA eco-system of Subscription Management, called “Remote SIM Provisioning” system.
The eUICC methodology allows each Connectivity Provider control of their “domain”, which effectively gives them control of the SIM while their Connectivity is being used. This allows them to provide their services directly to the user. The user however always keeps control of the ability to switch the Connectivity Provider at any point.
