# Device tab

> Find details about the last known device a SIM was seen in, including the device ID, IMEI, modem and hardware, and basic device settings like the required APN and secure tunneling.

The **Device** tab shows the last known device a SIM was seen in. SIMs can move between physical devices, so device details are tracked separately from the SIM. Device information is based on IMEI information provided through session data if and when available, and Hologram generally does not manage information about your devices.

## Last known device card

The primary identifiers for the last known device. IMEI is collected from session data when provided by networks and carriers. Device information is provided for reference if and when available.

</Accordion>

## Hardware card

What Hologram can determine about the device's hardware from the IMEI TAC if we have associated hardware information for it.

<Accordion title="Field descriptions">
  <ResponseField name="Modem">
    Name of the modem manufacturer, if it can be determined.
  </ResponseField>

  <ResponseField name="Hardware">
    Hardware model, if it can be determined.

## Device settings card

Settings that affect the device a SIM is installed within, based on its enabled profile.

<Accordion title="Field descriptions">
  <ResponseField name="Required APN">
    The Access Point Name (APN) your device needs to connect through the SIM's enabled profile. If the SIM's profiles require different APNs, all of them display, and your device must switch APNs when the SIM switches profiles. [Learn how to set the APN](/guides/get-started/set-the-device-apn).
  </ResponseField>

  <ResponseField name="Secure tunneling">
    Whether secure device tunneling with [Spacebridge](/dashboard/sim-actions/spacebridge-tunneling) is enabled and available through the SIM's enabled profile.
  </ResponseField>
</Accordion>
