What plans are eligible for the Family account?

To start a family account, you need to be on a 1-Month Unlimited Plan. To add any current Ultra subscriber to your Family Account, they can be on any plan as long as they are either in the last month of that plan cycle, or they are on a 1-Month plan. After a Secondary Line is added to the family, they will eventually be converted to the same plan that the Primary Line is on, but with the Add-A-Line discount. The 1-Month Unlimited Plan is the only plan that is currently eligible for the Family Account.
