how to recover deleted texts on iphone 11

You show to still be running iOS 15, is that true.

Assuming it is, IF you have not turned on iCloud Messages and IF the deleted texts are in your last backup then you need to restore your iPhone from that backup. You will lose any data added since the date/time of that backup. Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

If you have updated to iOS 16 and you deleted them while running iOS 16 follow this -> Delete and recover messages on your iPhone or iPad - Apple Support

We assume you have updated to iOS 16.
