# SIM and device details tab

> The **SIM and device** for a single SIM provides detailed information about settings, IDs, and configuration information for a Hologram SIM, and any information we have about the device we last saw it in as provided by session records. Information provided in this tab is similar to device details returned through the REST API.

## SIM details card

This card contains the primary identifying details for a SIM, configuration details, activation information, and SIM-level settings.

## Last known device details card

Details about the last known device the SIM was seen in. SIMs can move between physical devices, so these details are tracked separately. Device information is based on IMEI information provided through session data. Hologram generally does not manage information about your devices.
