No alerts for voicemails, settings set to alert and are also greyed out (i.e. unable to toggle the setting off then on again)

[NH9]

I have read a lot of forums but am not seeing exactly the issue I am having.

I have the following phone and versions

Galaxy S20 FE 5G - UI version 5.1 - Android version 13

Call about info:

version 14.7.09

Call version 14.5.00.50

You can see that the voicemail settings are set to what I want, but they don't work and b/c the 'allow notifications' toggle is greyed out, I can't toggle the setting off and on to see if that fixes the problem. i did recieve voicemail notifications in the past, but have not for about a year.

i did install youmail for a period of time to get notifications from a different method, and that worked for a little while but has stopped working as well.

anyone know how to re-enable management of this setting or other tricks to get the notirciations back. also open to 3rd party apps at this point.

Hi
Try Below

Open the Phone app Phone.
It's the icon that resembles an old fashioned phone. Tap the icon to open the Phone app.

Tap the Menu icon ⋮.
It's the icon with three dots in the upper-right corner of the Phone app. This displays the menu.

Tap Settings.
It's one of the options listed in the menu. .

Look for call-forwarding option.
Where this is located will be different depending on the model of your phone and your carrier. It may be under More Settings, Advanced, or Supplementary services.

Select the call-forwarding option. This will usually say something like Call forwarding or Forwarding settings.

Tap a Call-Forwarding setting.
The call forwarding options are usually something similar to Always forward, Foward when busy, Foward when unanswered, and Forward when unreachable. Tap one of these options

Tap to turn off or On

i found the setting, but when i open up "sumplementary settings" i get this

if i click ok and then click call forwarding, i get the same thing

my sim works for calls texts, etc. not sure what else to check

i can click the individual settings, but there is no "on or off" it just gives me a dialog to enter a number in to forward to
