# Exiting the sandbox

The SMS notification channel with an individual sender is originally created in the [sandbox](../../concepts/sms.md#sandbox).

After practicing on test phone numbers, you can apply to exit the sandbox mode:

{% list tabs group=instructions %}

- Management console {#console}

  1. In the [management console](https://console.yandex.cloud), select the folder you want to create a notification channel in.
  1. Navigate to **Cloud Notification Service**.
  1. Select an SMS notification channel you need with an [individual sender](../../concepts/sms.md#individual-sender).
  1. Click **Leave sandbox**.

      With that done, a tech support ticket to exit the sandbox will be automatically generated.

      You can also request an increase in the service quotas together with your request to exit the sandbox mode.

{% endlist %}

Once the ticket is approved, you will be able to send SMS messages to any Russian phone numbers in [E.164](https://en.wikipedia.org/wiki/E.164) format, e.g., `+79991112233`.
