Voicemail indicator on Galaxy S9

Is there an app I can install that would show a notification when I have a voicemail? I’m on Android. Thanks!

All phones have built in notification that pops up when u have voicemail.
Check you phones Phone app under Voicemail to see if the notification is enabled, or the system Notifications under settings for the Phone app, maybe notifications for the app were muted or hidden accidentaly.

i do not have a Samsung phone to give exact menu steps, but i found this online:
