I use the imessage function of iphone to send messages, and my ipad can also receive corresponding messages. Why can I only use my mobile phone to send and receive messages?

Let's take Apple's 6S mobile phone as an example to show you.

1. First, click Settings on Apple's mobile phone desktop.

2. Then click on the personal account information at the top of the screen.

3. Then click icloud.

4, and then click turn off the information switch.

5. After this operation is completed, the information received in Apple's mobile phone will not be synchronized to ipad.
