Do not disturb the setting of Apple xr dual card dual standby, can the owner still make a phone call while talking? What did you hear when you called?

I heard: "The number you dialed is busy".

You can set the phone to turn the Do Not Disturb mode on or off at a fixed time. When the "Do Not Disturb Mode" is turned on, the incoming call and suitcase will be muted when the screen is locked, and the moon icon will appear in the status bar; For those who like to put their mobile phones by their pillows when they sleep at night, you can set a fixed time to turn on the do not disturb mode at night and turn it off the next morning.
