Why my contacts have disappeared? How to get them back? The story started in November 2019, I bought a new IPhone in exchange of the earlier one. When I signed in with my Apple ID in new phone I didn’t get all my contacts, so it seemed to me that after the last backup I saved many more contacts and didn’t take their backup that’s why those new contacts weren’t appearing when I signed in and restored. 

However, I started saving new contacts as I was using my new phone, I saved many contacts (somehwhere around 45-50) but few days earlier I found that some of those (I don’t know if all) contacts have disappeared! It’s a little spooky but it’s a loss to me, I really need those contacts back.

Please suggest me something.
I think you should sign into the site of iCloud to view all the contacts every time you saved contacts.
