Choose to receive notifications for incoming calls, messages, missed calls, and voicemails. Notification Settings (System Level) Tailor notification settings on the system level in iOS, not the Dialpad app. Determine if alerts are displayed on your lock screen, in Notification Center, and as a banner. You can also toggle sounds and badges. 1. Go to Settings and find the guilty app in the long list of apps on that page and tap it. 2. Tap on Notifications. 3. Tap on Badge App Icon to turn them off (you can also turn off other notifications from the app if those are particularly annoying here too by tapping None in the Alert Style at the bottom).
