Use a different Apple Account. When using the same Apple Account across devices, the purpose is to share content where you can start an activity on one device and finish on another. You can find data being shared such as Messages, Call History, and Voicemails also. Review the information provided here for what you can expect for devices sharing the same Apple Account.
