The SM-DS provides a means for an SM-DP+ to reach the eUICC without having to know which network the device is connected to. This feature is important as devices can be connected using different access networks with different addresses. The SM-DS overcomes this by allowing SM-DP+ to post alerts to a secure noticeboard and for devices to extract those alerts.

It notifies the LPA when Profile data is available for download to the eUICC. Notifications are sent from the SM-DP+ to the SM-DS. The device LPA polls the SM-DS for notifications when required (supporting the “pull” model). Polling frequency is determined by the eUICC state and by end-user actions.
