# SIM details tab

> Find a SIM's identifiers, configuration, fallback behavior, settings, and key dates in the SIM details tab, and change settings like data limits and data warnings.

The **SIM details** tab shows how a single SIM is identified and configured, how it falls back between profiles, and the settings and key dates for the SIM. Details about the device the SIM was last seen in are on the [Device tab](/dashboard/sims/sim-details-device-tab), and details about each installed profile are on the [Profiles tab](/dashboard/sims/sim-details-profiles-tab).

## SIM details page content

### Identifying information

The primary identifiers for the SIM and its enabled profile.

<Accordion title="Field descriptions">
  <ResponseField name="SIM name">
    Name of the SIM. To rename the SIM, use the name in the page header.
  </ResponseField>

  <ResponseField name="SIM ID">
    Hologram's unique ID for the SIM card. Click to copy to clipboard.
  </ResponseField>

  <ResponseField name="EID">
    The eUICC identifier (EID) is the permanent ID of the chip in the SIM. It doesn't change when profiles are added to or removed from the card. Displays only for SIMs with an EID.
  </ResponseField>

  <ResponseField name="Profile MSISDN">
    MSISDN of the enabled profile on the SIM.
  </ResponseField>
</Accordion>

### SIM details

Details about the SIM's configuration and specifications.

<Accordion title="Field descriptions">
  <ResponseField name="Configuration">
    The profiles on the SIM, in configuration order, shown as pills. The enabled profile is highlighted. A ticket icon marks the first backup profile the SIM would move to, and profiles the SIM can't or won't switch to are dimmed. Hover over a profile to see its name, ICCID, Profile/Link ID, installation status, network status, and, if the SIM has an intended configuration, what that configuration asks of the profile. Select a profile to open its [profile details](/dashboard/sims/sim-details-profiles-tab#profile-details).
  </ResponseField>

  <ResponseField name="Description">
    Displays only for SIMs that connect using a single profile and have no fallback configuration.
  </ResponseField>

  <ResponseField name="Required APN">
    The Access Point Name (APN) your device needs to connect. If the SIM's profiles require different APNs, all of them display separated by slashes, with the enabled profile's APN emphasized, 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="SIM type">
    The coverage type of the SIM, like Dual-Core SIM, Multi-Core SIM, or Single-Core SIM. Hover over the information icon for what the type means.
  </ResponseField>

  <ResponseField name="Spec / Provider">
    The eUICC specification and provider of the SIM. Displays **Unknown** if it isn't available.
  </ResponseField>

  <ResponseField name="Format">
    The physical format of the SIM, like Tri-cut, MFF2, or eSIM.
  </ResponseField>

  <ResponseField name="Printed SKU">
    The SKU printed on the SIM hardware. Displays **Not available** if it isn't known.
  </ResponseField>
</Accordion>

### Fallback configuration

How the SIM falls back between its installed profiles. This card doesn't display for SIMs that can't use or don't support fallback, like single profile UICC SIMs.

<Accordion title="Field descriptions">
  <ResponseField name="Coverage type">
    Whether the SIM is protected against outages on a single profile:

    * **Fallback enabled:** The SIM automatically falls back to a backup profile if the primary profile loses connection. With Outage Protection™, you also have a guaranteed uptime SLA.
    * **Dual-core capable:** The SIM has multiple profiles installed, but fallback isn't active.
    * **Single-core SIM:** The SIM has a single profile installed and depends on a single carrier for connectivity and coverage.
  </ResponseField>

  <ResponseField name="Description">
    A plain-language summary of the SIM's current configuration, with profiles shown as pills.
  </ResponseField>

  <ResponseField name="Fallback mode">
    How the SIM switches between profiles automatically. SIMs with a SKU ending in "-F" default to **Return to previous** fallback mode. **Return to previous** switches between the primary profile and a single target fallback profile. SIMs with a SKU ending in "-R" default to **Cyclical** fallback mode. **Cyclical** moves through the backup profiles in order and then return to the primary profile after a Recovery Period.
  </ResponseField>

  <ResponseField name="Fallback timer">
    How long the SIM tries to reconnect on its enabled profile before it falls back to a backup profile. Default is 15 minutes.
  </ResponseField>

  <ResponseField name="Recovery timer">
    How long the SIM waits before it tries to return to its primary profile. Displays only for SIMs that support a recovery timer (SKU ends in "-R"). Default is 24 hours.
  </ResponseField>
</Accordion>

### Intended configuration

The configuration the SIM is meant to be in. For organizations with an active contract, this generally matches the contracted configuration for the SIM so you can see how the SIM's current configuration compares.

This card lists only information that differs from the SIM's current configuration. Select **Details** to compare the current and intended configurations side by side.

## Settings card

All the settings that can be configured or otherwise are available to or limited for a SIM, such as data usage limits and communication settings. Editable fields will show an edit icon and can be clicked. Some settings are restricted to certain roles, configurations, SIM types, or based on the SIM's installed profiles.

<Accordion title="Field descriptions">
  <ResponseField name="Data limit">
    The SIM's [data usage limit](/dashboard/sim-actions/set-usage-limits) at which the SIM is paused.
  </ResponseField>

  <ResponseField name="Data warning">
    The SIM's [data usage warning threshold](/dashboard/sim-actions/set-data-warning-threshold).
  </ResponseField>

  <ResponseField name="Outbound SMS limit">
    The SIM's [outbound SMS limit](/guides/rest-api/set-a-sims-sms-limit-using-the-rest-api) at which the SIM is paused.

  <ResponseField name="Phone number">
    The SIM's [phone number](/dashboard/sims/sim-details-pricing-tab), if purchased and available.
  </ResponseField>

  <ResponseField name="SMS">
    Displays when some or all of the SIM's profiles don't support SMS. Profiles that don't support SMS can't receive messages sent from the dashboard or API.
  </ResponseField>

  <ResponseField name="Secure tunneling">
    Whether [Spacebridge](/dashboard/sim-actions/spacebridge-tunneling) secure tunneling is **Enabled** or **Disabled** for the SIM. If none of the SIM's profiles support it, the row reads **Not supported**, with the SIM's current setting in parentheses. Displays only when Spacebridge is available to your organization. If the SIM's enabled profile doesn't support secure tunneling, the setting can't be changed and your device cannot connect via Spacebridge.
  </ResponseField>

  <ResponseField name="Location data">
    Displays when some or all of the SIM's profiles don't support location data, or when location data is turned off for your organization, in which case it reads **Disabled**. Sessions on profiles without location data have no country or tower location.
  </ResponseField>

  <ResponseField name="Update location">
    Displays when some or all of the SIM's profiles don't support updating location. A [network refresh](/dashboard/sim-actions/network-refresh) can't update the location of a SIM running a profile without it.
  </ResponseField>

  <ResponseField name="SIM webhook">
    Whether a [webhook](/dashboard/sims/sim-details-webhook-tab) is **Configured** for the SIM or **None**. Displays only when webhooks are available to your organization.

</Accordion>

## How do I resolve configuration warnings?

<AccordionGroup>
  <Accordion title="Not on the preferred profile">
    Your SIM has fallen back or switched to a backup profile and is not on the preferred profile for its configuration. Select **Switch profiles** to [recover the SIM manually](/dashboard/sim-actions/switch-profiles).
  </Accordion>

  <Accordion title="Target fallback profile can't be switched to">
    On a SIM using the **Return to previous** fallback mode, the target fallback profile is in a network state that doesn't allow switching profiles. The SIM can't use Outage Protection™ or fall back automatically until you switch profiles manually to update the state of the SIM.
  </Accordion>

  <Accordion title="Your SIM uses two APNs">
    If profiles installed on a single SIM use different APNs, your device must be able to identify and switch APNs when the SIM switches profiles. [Learn how to set the APN](/guides/get-started/set-the-device-apn).
  </Accordion>

  <Accordion title="A Conductor configuration event is in progress">
    Conductor is running eUICC operations on your SIM and may take some time to process. Some actions on a SIM aren't available while this process is underway. Conductor event records and any errors that occurred can be found in the [Events tab](/dashboard/sims/sim-details-events-tab) or in the [Event monitoring → Event history](/dashboard/event-monitoring/event-history) page.
  </Accordion>
</AccordionGroup>
