fix iCloud Because of the free 5GB storage with every Apple account, most iPhone users sync their data to iCloud. Keeping your data backed up to Apple’s cloud storage is a good idea because you can access iCloud from the web, and syncing your contacts to iCloud is a significant part of that backup to restore them whenever you reset your iPhone or upgrade to a new one.

Quick suggestions:

• Check that you’re using the same iCloud account across all of your devices.

• Sign out and restart your device, then sign back in with the same iCloud ID.

• Check your internet connection because it may be causing contact synchronization issues.


Any sync or backup action need a consistent internet connection. You may be utilizing mobile data to get to the office or another meeting. As a result, utilizing mobile data while on the go may result in unsuccessful contact sync.


Instead, anytime you connect your iPhone to a reliable Wi-Fi network, make sure that the iCloud sync for contacts and other data on your iPhone occurs. We propose that you access iCloud.com in a browser once in a while and compare the synced iPhone contacts.


When you connect to a metered network or a mobile hotspot, your iPhone will immediately enter Low Data Mode. While you may readily use other programs, the low power mode inhibits most types of background sync, including contact sync. Here’s how to disable the low data mode.


Set contacts to sync with iCloud as the default account

If you just signed out and back into iCloud, you’ll need to manually modify your Contacts app’s default account sync settings. To do so, follow along.

Set contacts to sync with iCloud as the default account

If you have changed the Contacts app’s default account settings to any third-party accounts, you may discover that some contacts stored on your iPhone are missing on other devices. You may manually search and add the missing contacts to your Contacts app to address the sync contacts from iPhone problem. When you backup your iPhone contacts using iCloud, the missing contacts will be added and stored to the iCloud library.

Open the “Phone app” on the iPhone.

Then go to “Contacts” and then “Groups.”

Press the “All iCloud” option to uncheck it.

Now tap “All [iPhone name]” to select it.

Press the “Done” button on the top-right corner of the app.

After a few seconds, turn off the device and resume it.

Switch on or off iCloud syncing

If the iPhone contacts are still not synchronizing to iCloud, turn off iCloud syncing and then turn it back on to give it a rebooted push.

Open the Settings app and navigate to your “Profile.”

In the Profile, go to “iCloud,” or if you’re using iOS 10.2 or earlier, you can go to iCloud directly from the Settings app on the first page.

Toggle the Contacts toggle button to disable iCloud Contacts syncing. iPhone will prompt you a selection popup, select the “Keep on My iPhone” option.
