You can even have the mute button on, and if a text is sent (whether from a favorite contact or not), the phone will play the text notification sound.” While (when it works) iOS do-not-disturb will block voice calls, it does not - in any of its various configurations - block text messages. “Another major problem is in the way iOS do-not-disturb is designed.
“What I found was that do-not-disturb, in its various incarnations, is very limited. “You can selectively block some iMessage contacts and threads (especially useful in huge group texts), but that can only happen once a first text or contact has been received. All the iMessage texts sent got through even when DND was enabled,” Gewirtz writes. “I found that some SMS texts did get through, but others didn’t.
“I also asked a few other iPhone users to try it out, and they, too were unable to get DND to block iMessage texts.” “I’ve read a bunch of articles that say DND blocks texts, but in my testing, I was quite surprised that DND didn’t block any texts,” David Gewirtz writes forZDNet.
