All my contacts are gone please help

After each step, see if you still need help:

1. Check for updates to your iPhone, iPad, iPod touch, Mac, or PC. To use iCloud, your devices need to meet the system requirements.
2. See if the date and time settings on your iPhone, iPad, iPod touch, Mac, or PC are correct.
3. Make sure that you're signed in to iCloud with the same Apple ID on all your devices and check your settings.
   • On your iPhone, tap Settings > [your name] > iCloud. (If you're using iOS 10.2 or earlier, tap Settings > iCloud.) Check your Apple ID and make sure that you turn on what you want to update (Contacts, Calendars, or Reminders).
   • On your Mac, choose Apple menu > System Preferences > iCloud. Check your Apple ID and make sure that you select what you want to update (Contacts, Calendars, or Reminders).
   • On your PC, open iCloud for Windows. Check your Apple ID and make sure that you select what you want to update (Mail, Contacts, Calendars, and Tasks).
4. If you sign in to third-party apps with your Apple ID, protect your account with two-factor authentication and use an app-specific password. If you don’t have devices that can be updated to iOS 9 or OS X El Capitan or later, you can set up two-step verification instead.
5. Open Safari and go to www.apple.com to check your connection. If you can’t open the page, get help connecting to the Internet.
6. Open a secure website, like your Apple ID account page, to see if you can access port 443. If the website won't open, contact your Internet service provider for help. Safari needs access to port 443 to update your information in iCloud.
7. Keep your data within the limits. If you go over the limit, your data won't stay up to date.

After each step, check your contacts, calendars, or reminders.

Set iCloud Contacts, Calendars, or Reminders as your default

2. Deselect the All [account] option for any third-party account, like Gmail or Yahoo.
3. Make sure All iCloud is selected.
4. Tap Done to see your list of contacts. If you don't see the contact you're looking for, it's stored in another account.
5. You can import the contact from a third-party service into iCloud.

Set iCloud as the default account for your contacts in iOS 8 or later:

2. See if the list is stored on your device or iCloud. Open a list and tap Edit. If you see Sharing, then your list is in iCloud.

When you create a reminder, you can choose to store it in iCloud or on your iOS device.

Check your app settings

Make sure that your iCloud Contacts, Calendars, and Reminders are set to appear in the Contacts or Calendars app:
