# SIM Card Status Change Notifications

### 17, Dec 2021

You can now send email notifications to any address when one of your SIM cards changes status. This adds more visibility into your SIM behavior, so you can know when any of your SIMs are enabled, disabled, or on standby. This functionality is especially useful in knowing when one of your standby SIMs has been activated via [usage-based activation](https://telnyx.com/release-notes/usage-based-activation).

You can configure SIM Card Status Change notifications by adding a new setting in the [notifications section of your Mission Control Portal](https://portal.telnyx.com/#/app/account/notifications/settings), or find out more about notifications in our [support knowledge base](https://support.telnyx.com/en/articles/4277896-notification-settings).
