取消个人 iCloud 方案加入家庭组 iCloud 方案数据会丢失吗？

不会

取消 iCloud 订阅以后数据不会丢失，但所有新数据无法保存到 iCloud 中，直到 iCloud 占用空间降到免费的 5G 以后才能继续更新。

我记得，我以前加入家庭组不需要取消个人 iCloud 也能直接加入家庭组 iCloud，而且个人 iCloud 会按使用时间来给你向原付款渠道退款。

不会

一段时间内不会被删除的
应该是直接加入家庭组就可以了，个人方案会自动取消。

> If a family member is already paying for their own iCloud+ plan, they can choose to switch to your plan or keep their own and still remain part of the family. When they switch to the shared family plan, they get a refund for the remainder of their personal plan. They can't keep their current plan and use the shared family plan at the same time.
