How to use iCloud cloud messaging on iPhone?

If "information" is the data that is very important to you in the iPhone, you can use the iCloud cloud information function to synchronize. ICloud can update all your information history, and even if you set up a brand-new device, you can view it on all devices.

Before using this function, you need to do the following:

1. Log in to your Apple ID on each of your Apple devices and make sure they are all logged in with the same account.

2. Turn on double authentication for your Apple ID to ensure account security. On the iPhone, you can turn on two-factor authentication in Settings-[Your Name]-Password and Security.

3. Set up iCloud keychain: With iCloud keychain, you can keep passwords and other security information up to date on all devices.

Tap Settings-Your Name -”I cloud and swipe to open iCloud keychain.

Turn on iCloud cloud information function.

When the settings are finished, open Settings-Your Name-Tap iCloud to open Messages.

When opened, iCloud cloud information will be updated automatically, so you can see the same content no matter where you use iMessage information. When you delete a message, photo or conversation on one device, it will also be deleted from all your devices. In addition, since all attachments are stored in iCloud, you can save space on your device.

When setting iMessage information, you will be prompted: What if cloud information is unavailable?

The above prompt is caused by the inconsistency between iCloud and iMessage information accounts. Please make sure that you sign in with the same Apple ID on all Apple devices and bind to your latest email address or phone number.
