Subscription Manager Data Preparation (SM-DP+)
The SM-DP+ is the operator-side server that prepares, encrypts and delivers eSIM profiles to a specific eUICC.
What is Subscription Manager Data Preparation (SM-DP+)?
The "+" marks the enhanced version used in consumer RSP, which combines the preparation and secure delivery roles that were split in the earlier machine-to-machine model. The SM-DP+ binds each profile to one target eUICC so it cannot be installed elsewhere.
