How does Apple 6sp cancel the Do Not Disturb function of deleted SMS?

Set information options in the system.

1. When we open iMessage on iPhone, we often receive some spam messages. And they are from different Apple ID accounts. Usually, you will see that the sender is just some email accounts, such as bills, false advertisements and so on.

There is a way to prevent these short messages from disturbing us, that is, they are not displayed on the screen and there is no sound reminder. Please open the Settings application on the home screen first;

3. Find the column of "Notice" in the setting list and click Enter;

4. In the application list below the notice, click to open the "Information" column;

5. Next, please select the option of "Reminder from my address book only" in the setting list of information notification to block the display and sound reminder of strange spam messages.
