> How to release SIMs from specific devices using the emnify Portal

Releasing a SIM from a device is a standard operation in the emnify Portal that allows you to manage your IoT connectivity more effectively.
This process involves unbinding a SIM card from its associated device, which can be useful in various scenarios.

There are several reasons why you might want to release a SIM from a device:

* **Reassignment**: You want to assign the SIM to a different device.
* **Device status management**: You need to troubleshoot a device that's not performing as expected, and releasing the SIM changes the [device status](/portal/connected-devices#device-status) to **Disabled**.
* **SIM status management**: Helps organize your SIM inventory and allows for SIM reuse.
* **Device deletion preparation**: Releasing the SIM is necessary before deleting your device from the Portal.

All SIMs keep their current status when released from a device, except for **Activated** SIMs, which become **Suspended**.

> For more information about how the SIM and device status interact, see [Device troubleshooting](/portal/troubleshooting#how-sim-status-and-device-status-interact).

It's important to note that releasing a SIM is a reversible action.
You can always reassign the SIM to the same or a different device later if needed.

## Individual device

[Log in to your emnify account](https://portal.emnify.com/sign).

Navigate to your [**Connected Devices**](https://portal.emnify.com/connected-devices).

Find the device from which you want to release the SIM and hover over the table row to reveal quick actions.

Select **More options** and then **Release SIM**.

> **Warning**
>
> This action has no confirmation dialogue, so make sure you're releasing the SIM from the correct device.

## Multiple devices in bulk

It's also possible to select several devices on the Portal and release all their SIMs simultaneously.

Navigate to [**Connected Devices**](https://portal.emnify.com/connected-devices).

Search for the devices where you wish to release the SIM and select the checkbox next to every relevant device.

A new menu at the top of the page provides bulk operations.
Select **More** and then **Release SIM**.

Review the information on the modal, then select **Confirm**.
