Some of my messages are missing since I got a new phone yesterday

Hi Cmaygirl,

When you received your new phone, did you restore your data from an iCloud backup, or did you use another method like Quick Start to transfer your data? If you used the iCloud method, we recommend that you take a look at the article here: About missing information after you restore your iPhone, iPad, or iPod touch with iCloud Backup - Apple Support

Next, we'd like to show you how to perform the recommended troubleshooting steps via the link above. Please click to open the link, then read through the steps in the section titled "About your Messages and Voice Memos data."

With Messages in iCloud and Voice Memos in iCloud*, your text messages and voice recordings automatically upload to iCloud. They aren’t included in your backup. After you restore your device from iCloud Backup, stay connected to Wi-Fi so that your text messages and voice recordings can download.

If you turn off Messages in iCloud, your text messages and attachments no longer upload automatically, but they save in your next iCloud Backup and download in the background when you restore. Stay connected to Wi-Fi until the process finishes. The time it takes to restore depends on the size of your backup and the speed of your Wi-Fi.

Sometimes, if you restore a device from a backup of another kind of device, your Messages and Voice Memos won’t restore. For example, if you use an iPad backup to restore an iPhone, your Messages and Voice Memos may not appear on the iPhone.

If your information is still missing after you restore, you can try to restore from a different backup in iCloud or on your computer. Always back up your current data on your computer before you try to restore from iCloud Backup.

The reason why we are recommending the steps above is because they will show you what to do if you're missing messages after you have restored your iPhone from an iCloud Backup.

Please do not hesitate to reach back out to us if you have questions or need any additional support.

Thanks for using the Apple Support Communities.

Cheers!
