Hello trong-147,

You can use iCloud with Messages to keep all your messages up to date with iCloud. When you delete message conversations, they are removed from each device. Here's how to turn on Messages in iCloud:

To turn on Messages in iCloud, make sure that you've set up iCloud and are signed in with the same Apple ID on all your devices, and that you've turned on iCloud Keychain. You also need to use two-factor authentication with your Apple ID.

On your iPhone, iPad, or iPod touch

1. Go to the Settings app.

2. Tap your name.

3. Tap iCloud.

4. Turn on Messages.

On your Mac

1. Open Messages.

2. In the menu bar, choose Messages > Preferences.

3. Click iMessage.

4. Select the checkbox next to Enable Messages in iCloud.

Additional information can be found in Use Messages in iCloud - Apple Support.

Take care.
