I have no idea why my contacts are suddenly disappearing from my iPhone 16! I had Siri make a call. It went straight to voicemail. I hung up and tried the other number. I was then informed that the contact isn't in my phone book. The same thing happened with my husband and another friend. This is scary!

What is your default Contacts account? If none, please add an email account and enable contacts.
Contacts: Restore contacts stored in iCloud on iCloud.com
Unlike some Android devices, contacts are neither stored locally on an iPhone nor in 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.
