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.
