How to synchronize SMS between two Apple phones;

First of all, the information synchronization between two Apple devices mainly uses the same iCloud account, and both of them have the iCloud cloud synchronization function enabled, so the information synchronization function will appear.

To cancel the synchronization function between two mobile phones, you can only turn off the iCloud cloud synchronization function, or replace one of the devices with a new iCloud account.

Turn off iCloud cloud synchronization settings and electrical equipment settings -iCloud, and turn off the option of synchronizing information in iCloud, so that the information in iCloud will not be uploaded or downloaded synchronously.

Changing a new iCloud account will also prevent the same information from synchronizing with each other.
