How to restore iPhone from old backup?

My phone got stolen last night and he erased all my messages before I was able to lock it. He tried to sell it today so I got it back. Anyways, I'm wondering if there's a way to recover my messages through my old backups? If so, can anyone guide me? The new iTunes is kind of tricky to me. I don't want to completely restore my phone and lose all my contacts and everything, was just hoping to get my texts back.

If you made an iCloud backup then it is possible to get things right there where they used to be earlier.

I recommend you to use iphone data recovery for mac which can help to recover any data through your old backups with ease. It supports recover up to 12 files like contacts, SMS, photos, call histories & more with ease. Have a try
