How to import SMS messages from old Apple phones into new phones?

To import between Apple devices, you can sync with an icloud account. First, open the settings on Apple's mobile phone, click the iCloud option and log in to your Apple ID account. If you don't have an Apple ID account, please press the Create Apple ID Account button to create an Apple ID account. After the Apple ID account logs in to iCloud, turn on the information switch. Log in to the same Apple ID account on another iphone and turn on the switch to get information.

You can also use third-party software, such as QQ's file transfer function. Just click the plus sign on the top right of QQ homepage, click face-to-face quick transfer, select the receiver, and then use another mobile phone to select the sender.
