Galaxy S8 with Android 9. T-Mobile pre-paid
I decided not to have voicemail for now due to the season and how many calls I have been receiving per day. However, I am getting the notification for new voicemail. I have tried - Settings > apps > (choose show system apps from the menu) > phone (the 1st one since there are two) > storage > clear data and clear cache. Then I restart my phone. The notification still shows up.
I called T-Mobile yesterday and was on the phone with the rep for about an hour. She tried different things and told me to do the above. Still get the notification.
Its driving me crazy!!!
