Where did the iphone stop texting?

Iphone prevents text messages from entering the address book. Take Apple X as an example, the situation is basically as follows:

1. Open the desktop of the mobile phone and click the icon with SMS to enter.

2. After entering, you can see that there are two options on the SMS page.

3. Then click the option on the right that is not in the address book.

4. Then you can see that the intercepted message is in it, because it is not in the address book, so it will be intercepted.
