How to synchronize SMS and call records between two iPhone?

If both iPhones have the address book function turned on in iCloud, the call records of two iPhones with the same ID will be synchronized.

1, iCloud is a private cloud space provided by Apple for Apple users, which is convenient for Apple users to enjoy personal data between different devices. ICloud supports user devices to push data wirelessly, which is simpler than Apple's traditional iTunes solution (which requires a data cable connection) and has a better user experience.

2. If you don't want two iPhones to synchronize call records, you can turn off the address book synchronization function in the iPhones respectively. The specific steps are to enter the iCloud panel in the settings of the mobile phone and turn off the address book function. The second method is to change the login ID of one of the iPhone.
