How does Mac set up to answer calls and send text messages?

1 iphone should be upgraded to iOS 8. 1, and OS X should be upgraded to 10. 10 Yosemite;

Both iPhone and MAC bluetooth should be turned on, but they don't need to be paired, just turn them on;

Both iphone and MAC Facetime should log in with the same iCloud account;

4 Two devices should be connected to the same WiFi signal;

Iphone cellular mobile network calls should be allowed in Facetime settings of 5 MAC;

6 Enter the "SMS Forwarding" page in the information settings of iPhone.

7 Then select a forwarding device, the device will receive a verification code, and then enter the verification code to bind the device in the iphone:

After the functions of sending and receiving short messages and answering phones are turned on on the MAC, as long as the iphone is around, you can completely disconnect from the mobile phone. For example, a phone call suddenly comes in the process of programming. You can click Answer on the MAC and write code while answering the phone. If you make a phone call while listening to music, the music volume will be automatically muted and the user experience will be good.
