MultiSIM CSP

The MultiSIM configuration service provider (CSP) is used by the enterprise to manage devices with dual SIM single active configuration. An enterprise can set policies on whether that user can switch between SIM slots, specify which slot is the default, and whether the slot is embedded.

The following list shows the MultiSIM configuration service provider nodes:

{ModemID}
