Our usage dashboard has all of the information you need.
To track usage in SuperPhone, simply navigate to the settings page and at the top you will see your usage for the month (to date).
Usage tracking is only updated daily and represents a summary of your bill to date for the month. To see more granular detail, click 'View Full Detail' or navigate to this link while logged into your account: https://app.superphone.io/settings/dashboard-usage
This is only enabled for a small beta group at the moment, so to enable this dashboard in your account, please send a request using the chat bubble in the bottom right of any SuperPhone screen.
