You don’t have to leave a group text on an iPhone just because you want it to stop buzzing with new message notifications! Instead, you can silence alerts and read the text messages later.
If you have iOS 15, you may also receive suggestions to mute a group chat you don’t seem to be engaged in. In this case, you can select the suggestion to mute. However, if you don’t see a suggestion to mute, you’ll need to follow the steps below to learn how to mute text messages on iPhone.
Open the Messages app.
Select the group message thread you want to silence.
Select the contacts at the top to edit your settings for the group.
Toggle on Hide Alerts. The toggle is green when enabled.
Select Done.
That’s it, if you still want to receive some alerts, but don’t want to see notifications on your Lock screen, you can turn off Lock screen notifications in settings.
