In the Session details tab of the User Console, the Event column indicates the specific behavior of the device's network connection:
- Created: The device has established a new network connection and can communicate with the network.
- Modified: An existing connection was updated (handover). This is typically due to the device moving between radio towers or switching connection technologies (such as 3G to LTE), or other factors related to signal strength or coverage.
- Deleted: The network connection was closed, and the device can no longer communicate.
Session history records are available for the past 32 days. If a session remains Online for more than 32 days, previous history records will be cleared. For more details, refer to the Subscriber Status documentation.
You can also retrieve session events programmatically using the listSimSessionEvents API.
