How do you restore contacts on iPhone 6s?

Hi Andrewbjeti,

Welcome to the Apple Community.

Wondering where you might have a back-up of your Contacts to restore them from.

Eg: iCloud, Mac, External Hard Drive etc ?

or

do you want to add them again from each e-mail account, SIM, directory etc.

Restore contacts, calendars, bookmarks and more using iCloud.com:

or

Set up mail, contacts, and calendar accounts on iPhone

and

Use other contact accounts on iPhone

Hope this helps :-)

Sync with iCloud:

Enable Contacts in iCloud on your iPhone. Once enables, they should pop up in your Contacts list. So, Perform the following...

1. Go to: Settings
2. Tap: Your Name (Top Item)
3. Tap: iCloud
4. Tap: Contact
5. Enable: iCloud Contacts

How many gb of icloud will it take minimum?

How Much GB:

Not even close to 1 GB (unless you have thousands of Contacts) - Probably in the KB or lower MBs.
