How to Recover Deleted WhatsApp Messages for IOS: 1) Uninstall WhatsApp from your iPhone. 2) Reinstall WhatsApp and set it up with your phone number. 3) Once the app is set up, you will get a prompt asking you to restore messages from a cloud backup. This backup would be from Google Drive on iCloud. Tap Restore. 4) This will bring back the messages that you had accidentally deleted. Note that if you got a message after your most recent cloud backup and deleted it, there's no way to recover it.
