1 Visual Voicemail Not Working?
Some people report problems getting Visual Voicemail to work in iOS 11 or iOS 12. If that’s the case, there are a few things you can try. The first thing you can do is to simply reboot your iPhone. If that doesn’t work, some people report that listening to a voicemail, turning Airplane Mode off and on again, or resetting their network settings help. It’s also worth updating to the latest version of iOS — as well as updating the carrier settings on your device.
