Identifying When a SIM Was Last Connected

You can view the connection status and history of Soracom IoT SIMs using either the Soracom User Console or the Soracom API.

Method 1: Soracom User Console

For checking a small number of SIMs, the User Console is the most direct method.

1. Navigate to the SIM Management page.

2. Locate the SIM you want to check. Click the checkbox next to the SIM, then click the Details button.

1. Click the Session Details tab. The most recent cellular session event is displayed at the top of the list.

Note: The Session Details tab only displays connection history for the previous 32 days. For more details, refer to the Subscriber Status documentation.

Method 2: Soracom API

You can also retrieve connection history programmatically using the Soracom API.

To check the history for a single SIM, use the listSimSessionEvents endpoint (GET /sims/{sim_id}/events/sessions). This call returns a list of session events, including timestamps, which allows you to identify exactly when the SIM was last connected.

For further information on available API calls, please consult the API Documentation.
