How I retrieve my deleted text messages f

go to Settings > [your name] > iCloud and check the switch position for Messages

If the switch is ON, then you cannot recover your deleted messages (no need to read any further)

If the switch is OFF, then you might be able to recover your messages IF you have an iPhone backup that contains the messages you are trying to recover. In which case you'd need to restore your iPhone to that backup. In doing so, you'd likely lose some data between now and whenever your backup occurred.

Deleted text messages are deleted.

If you're using iCloud to synchronize messages, they're gone.

If you're not using iCloud to synchronize messages and you have backups, you might be able to recover the messages by restoring a backup created prior to the deletion, though that will revert the entire contents of the iPhone and all changes.
