Iphone 5s can't be fixed and need backup can whatsapp

I had Iphone 5s and I broke it too many times that it can't be fixed anymore and i can't open it, i bought Iphone 7
I didn't have any backups on 5s though, Can I atleast get my numbers or pictures? Anything? Can whatsapp account get them back? Please tell me if there's any possible thing i can do. There are my bosses numbers and teachers i can't get them again if I lose them!

Did you have it linked to iCloud.com by any chance? Sign in with your Apple ID and your contacts, calendar and photos should all be up there. They should automatically come down from the cloud when you do the same on the new phone.
