Please see the pic below for a better understanding...



If you are unable to find your contacts which were stored on iCloud, then try this --> Restore contacts, calendars, bookmarks, and more using ...


Check if the email account has been removed from the iOS mail app.

Add the email account that stores your contacts in the IOS mail app and enable Contacts.



What is your default Contacts account?




Unlike some Android devices, contacts are neither stored locally on an iPhone nor in the SIM. They are synced to an email account that you have Google, iCloud, AOL, Exchange, Outlook, Yahoo, or any Other



If you have a corporate email account added through a profile on your device, please check with your organization's system administrator.




  1. Is this your corporate/organization/enterprise/School Management iPhone? Then please contact the system administrator of your corporate//organisation/enterprise/School Management
  2. If it is your device, in that case, do you have any profile installed by your corporate/organization/enterprise/School Management?
    1. Erase the profile added by you. If you have installed a profile on your own, --> Install or remove configuration profiles on iPhone - Apple ...
    2. Please contact the system administrator of the organization who provided the profile to you

Both my wife and I have 18.6.1


my ip16 seems fine

her ip15 has problems


Many of her contacts have disappeared, but when clicking on info in messages of one showing just a number, this shows the contact details ?


another difference is ;

settings, apps, contacts - mine shows default account is my MS account


my wife’s does not even show the default account menu item.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.



Remember, the right question often leads to the solution!



Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.



iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.


Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.


Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Same thing happened to me, I’ve spent hours on the phone with Apple and their IT specialists and they have been extremely unhelpful and avoidant of the problem. I tried every solution -nothing has worked. Finally someone on Apple support told me they had been getting a lot of calls about this issue and were aware. Unfortunately their only advice for me was that it was okay if I start resaving contacts and that maybe a software update would fix the bug. I lost hundreds of contacts that I need for work so this has been extremely inconvenient.

Your last question is exactly what's happening to me. I did lose about 1/3 of contacts a few weeks ago, sometime afte the 18.6 update. Rounds with applecare and i had to do a full restore on my phone which did restore all contacts. Through that process all of my default contact saves, syncing, etc were all 100% checked and rechecked. FF to this morning and between client appointments, about 1/3 of my contacts have gone missing again. In each case it is lots of my most recent contacts and instantly discoverable because almost all recent text messages appear as phone numbers. Just went through round one with Apple to no avail and came here to the forum. If I start to compsoe a text message and type a contact there, they appear, even thought that exact person's contact isn't findable in my actual contacts.

This has also happened to my wife after updating to iOS 18.6 but her issue is different as not all contacts are gone but their names have been removed so we know who’s who.


I've tried everything the guy has said below but nothings worked.


Phone not jail broken.


I’ve read on twitter thats theres other users also experiencing these issues and similar.

This happened to me too after updating to iOS 18.6.


Strangely, only contacts that I saved through WhatsApp in iCloud contacts are missing.


And even weirder: My own contact poster in contacts got deleted (my number is still there) and my Apple Account picture also is gone, but only on my iPhone and iPad, not on my Mac.


There are multiple people on Reddit with the same problem: https://www.reddit.com/r/ios/s/4Q1xuJBbfw
