Just imagine that you've been doing housekeeping in iPhone's Messages app to clear some out-of-date iMessages: You swipe left over an iMessage conversation, tap Delete, and then tap Deleted again to confirm...Oops! The important information from that iMessage has never been marked down somewhere. That is frustrating, but you don't be annoyed with it—you can easily and safely recover the deleted iMessages on iPhone.
Obviously, you can't restore iMessage from the native app to undo your mistake. If you would like to know how to retrieve iMessages chat history you've accidentally deleted from iPhone, go ahead and read the post.
Option 1 — Restoring from iCloud without Overwriting iPhone
Apple iCloud now provides us with such a good feature as iMessages (Messages) Syncing. If it's been enabled, this won't be a tricky problem for you to restore iMessages on iPhone via iCloud.
1. Open Settings on iPhone, tap [Your Name] > iCloud.
2. Turn Messages sync OFF, and then choose "Keep On My iPhone".
3. Toggle Messages to ON state (the slider shows Green), then choose "Merge" in the popping up message.
4. Wait for a moment and the disappeared iMessage files will get restored and return to its original location on iPhone.

Option 2: Restoring Entire iCloud Backup on iPhone (Erase Settings and Data)
You can also try restoring a complete iCloud Backup to iPhone to get back iMessages that you deleted off iPhone. The iCloud backup should be created (iCloud Backup feature is enabled) since before the iMessages were deleted or lost.
1. Head to Settings > General > Reset > Reset All Setting and Contents.
2. Wait iPhone to reboot. Now set up the device following the instructions. When reach the screen labeled "Apps & Data", choose "Restore from iCloud Backup" (if you back up to iTunes, choose "Restore from iTunes Backup" instead).
3. Proceed to sign into iCloud account and choose the backup with the lost iMessages included, then the restoration should begin immediately.
4. Once done, access any restored iMessage conversations in iPhone Messages app. However, you will lose any newer data between now and the time the backup was made.
Restoring iMessages from an iPhone using iCloud (or iTunes) backup works in general, but what if you don't make backups of iMessages on Apple iCloud? Don't freak out, now you can restore iMessages from iPhone internal storage, and iPhone Data Recovery—a popular and professional files recovery tool for iPhones, allows you to do that.
It's geared mainly toward recovering accidentally deleted iMessages and other files on iPhone device and bring everything back to life without data loss. The built-in scanning mechanism helps finding how much deleted data can be recovered from iPhone or the backup without restoring an entire archive to iPhone. Its wizard-based interface makes it very easy-to-use for all users.
