Visible doesn't have any type of family plan. If you want to add a spouse or child just create an account for each one them. (remember to write down the email and password for each one). You can use the same address and same credit card for each. That's how I did it. My wife and two older teens all had their own account but all were paid for by the same credit card. Now its only myself and my wife. My kids broke off on their own.
