Q: How do i see saved text messages

Welcome to the Apple community.

If you've deleted text messages, you can only recover them by restoring your device from a back up.

I'm pretty sure you don't want to do this. This is restoring your entire iPhone from a backup, not just the photos.

I think if you send a text to someone, then scroll up, you will see a button to load earlier messages. I think this will do what you want.
