Contacts in iPhone 13 mysteriously changed

1) Recently one of my contacts name was changed to “Jack”. The phone number remained the same. It happened twice.


2) 7 contacts’ phone numbers were all changed to the same phone number of the contact in question number one above. Their original phone numbers were deleted.

The number format resembled overseas number beginning with 2 digits.


how is this happening??

Contacts sync from an email server to your phone. If you have the same email account on multiple devices any contact changes on any device will be reflected on all devices. So one possibility is that you aren’t the only user of that email account, and someone else made the change.


Another strong possibility is your email account was hacked, so change the password for it, and make it a good, strong password. And add 2 factor authentication if your email provider supports it.
