How about notifications, phone calls and text messages in iphone4 settings without meetings?

First, this will not consume traffic;

Second, if it is turned off, unknown incoming calls and unread information will not be prompted when the notification bar and screen are locked;

Third, phone and information icons will still prompt the number of missed calls;

Personally, if there is nothing special, it is recommended not to turn it off. After all, it doesn't consume traffic, and it can also prompt missed calls and text messages. Why not?
