How do I know a data plan is canceled

Hi Kp0813,

If you canceled an iCloud storage plan and want to make sure it was canceled successfully, please check out this link, which explains how to review and manage your iCloud+ plans: Downgrade or cancel your iCloud+ plan

Before you downgrade or cancel your iCloud+ plan, first download or remove content that exceeds your new storage amount. To make sure that you don't lose any information, learn how to copy what you store in iCloud.

For more information on sharing iCloud+ with family, please check out this link, which has information that may be helpful: Share iCloud+ with your family - Apple Support

Switch from your personal iCloud+ plan to your family plan

When you share iCloud+, any family members using the free 5GB plan are added to your family plan automatically.

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.

On your iPhone, iPad, or iPod touch 

In iOS 16 or iPadOS 16 later:

1. Go to Settings > Family.

2. Tap Subscriptions.

3. Tap iCloud+.

4. Tap Use Family Storage.

In iOS 15 or iPadOS 15 or earlier:

1. Go to Settings > [your name].

2. Tap Family Sharing, then tap iCloud+.

3. Tap Use Family Storage. 

Thanks!
