6. Clicking the *Broadcast Messenger* tile in *My Workspace* opens the application in a new tab.&#x20;
   * Two departments are created by default for SMS. This reflects the two new One API integrations: **Default Campaign** (used for sending production messages) and **Default Test Campaign** (used for testing whether your campaign’s setup is correct).
   * To **test** a campaign, a test phone must exist in the system. Add test phones via the Clickatell Portal as described [here](https://guides.clickatell.com/sms-channel/getting-started/add-and-edit-test-phones).&#x20;
