After installing the system update, try to connect to iCloud to check whether the Contacts have synced.

3. Use a Stable Internet Connection

Instead of using mobile data which is quite slower, try connecting your iPhone to a WiFi network. If you are already connected to a WiFi network on your iPhone, then make sure the network is stable.

Sometimes, the router may have malfunctioned momentarily or the ISP may be undertaking any repair work. It is better to call up your ISP support and confirm the same. Meanwhile, you can reset the router or try disconnecting and reconnecting to the network.

Alternatively, you may try connecting your iPhone to another WiFi network if it is possible. Some users have reported that toggling between flight mode activation and deactivation on their iPhones has helped in fixing the sync issue of iPhone contacts to iCloud. You may try that out as well.

  1. Open the control center on iPhone.
  2. Tap the Flight mode icon to enable it.

  3. Again tap the same icon to disable flight mode.

Once the network reinstates, you can check whether the iCloud is syncing the iPhone contacts.

5. Check if iCloud is Down

You have to visit the Apple System Status page to check if any of the iCloud services are down. It may be due to an overload of users or some routine maintenance when Apple takes the server down. You may even tag Apple Support on Twitter and confirm the same from them. Otherwise, directly connect with Apple Support and raise a ticket regarding your issue.

Check Apple Server

Apple is very efficient in keeping its servers up and running all the time, but there are exceptions to that at times. Usually, in no time Apple fixes up the servers for various services to resume their use worldwide.

6. Make Sure You Are signed in to the Correct iCloud Account

Are you using multiple Apple IDs or iCloud accounts? Then make sure you are signed into the correct iCloud account on the right device. Often people use multiple iPhones and are signed into different Apple IDs. They get confused if they access a certain iCloud and find no contacts synced to that.

Go to Settings to confirm which Apple ID you are correctly signed into or if you are checking another iPhone that has a different set of contacts that may not be synced yet to the iCloud account.

As an additional tip, you can sign out of the Apple ID and sign-in back again. It is a nifty trick that often works in resolving the stubborn sync issues on iCloud.

  1. Go to Settings > tap on Apple ID.
  2. Then navigate to Sign out and tap on it.

  3. Enter the Apple ID password to confirm the logout.
  4. Now, go to the Settings section and sign in with the same Apple ID or a different Apple ID depending upon which ID has the contacts synced to iCloud.

7. Set iCloud as the Default Account

Users do the simple mistake of not settings their iCloud account as the default for syncing contacts on the iPhone. Here is how to set your iCloud as the default account.

  1. Go to Settings > tap on Contacts.
  2. Tap on Default Account > Select iCloud.
    Set Default Account iCloud
  3. Now, check if the contacts are syncing on iCloud storage or not. That’s it.


After implementing all the above troubleshooting tips, I’m sure you will be able to fix the issue of iPhone contacts not syncing to iCloud. Having the contacts synced to the cloud storage can make it available on any Apple device you use at any point in time. So, resolve the problem to avoid missing out on your contacts.
