There’s little worse than missing and important call or text because your iPhone was in Do NotDisturb mode or because the Mute switch was engaged. If there are certain people – a spouse, parent, or child – whose calls and texts you always want to break through the cone of silence, iOS has the solution: Emergency Bypass. When enabled for a particular contact’s ringtone or text tone, Emergency Bypass ensures the sound and vibration will happen regardless of Do Not Disturb or theMute switch position. To set up Emergency Bypass, edit the person’s contact card in the Phone or Contacts app, tap Ringtone, and enable Emergency Bypass.You can turn on Emergency Bypass separately for calls in the Ringtone settings and for texts in the Text Tone settings. And remember, you can always set someone’s tone to None and enable a vibration instead to ensure Emergency Bypass doesn’t allow a call to interrupt a movie, play, or concert.
