Do you know that you can read deleted messages using WhatsApp Chat Backup?
It's very easy, I'm ready to give you the steps.
If you have deleted a chat accidently that you want to recover, you can do so with the help of WhatsApp Chat backup which occurs every night at 2 am by default. You can change the frequency of backup to daily, weekly or monthly. However, choosing daily as the preferred backup frequency is recommended as you can restore chats before the next backup occurs at 2 am.

To restore deleted WhatsApp chats, pursue the following steps:

•Uninstall WhatsApp and install it again from Google Play Store if you are using an Android device.
•Agree to Terms and Conditions and enter your mobile number along with the country code in the next step.
•You will be presented with an option to restore chats from a backup.
•Click on the restore option and your WhatsApp chats will be restored.
