Why didn't I receive the original text message when I changed my Apple phone?

SMS and mobile phone are bound, and the data is unique (the content can be repeated, but the time will never be repeated). Replacing the mobile phone is equivalent to updating the data in turn, and the original mobile phone data cannot be retained.

If you want to transfer the SMS, you can forward the current SMS to other mobile phone numbers, or you can save the SMS picture by taking screenshots (press the power button and the back button at the same time), and then save it to computers, network disks, USB flash drives, other mobile phones and other devices.
