iPhone 11 Randomly Blocked Contacts

I have an iPhone 11 on IOS Version 16.4.1. My iPhone randomly blocks contacts and loses voice mail.

I keep resetting the contacts over and over but it keeps turning on blocked contacts automatically. I tried to create new contacts and it will still treat them as blocked contacts. Anyone have any suggestions

Whare are your contacts stored?

When you look deeply you will find that Contacts are neither stored on an iPhone nor on SIM. They are synced to an email account that you may have added and enabled Contacts. It could be Google, iCloud, AOL, Exchange, Outlook, Yahoo or any Other email client server.

When you enable Contacts in any of the email accounts they are displayed to you through the Contacts App. When you edit these contacts on an iPhone they are ultimately edited on the client-server.

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

If you are unable to find your contacts which were stored in the email client, 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? If none, please add an email account and enable contacts.

Unlike some Android devices, contacts are neither stored locally on an iPhone nor in SIM. They are synced to an email account that you had 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.
