You are going to have to wait till your family gold plan is up, and then just make sure you have it set to NOT auto-renewal. Then just buy your 3 month plan or enter in the code. Once you are in the family plan, you can't switch out of it until the family
Well, actually as long as you are not the administrator of the family plan you can be removed from the family. That account will then go silver and you can put another 3 month code on it. If you are hoping to get off the family plan and not buy the 3 month
code but just have some of the months go "with you" then no, that won't happen. Also, if your account was started in the family account with a child birthdate, you will still need an adult to vouch for you. The now empty spot on the family plan can then
be filled by adding a different profile or creating a new one.
