VM App not working

[dataguru]

I have a S20+ 5G, unlocked with service through Straight Talk. I recently switched out the AT&T Sim card for a Verizon. After the switch, the visual voicemail no longer works, the voicemail app no longer works, and I no longer get voicemail notifications.  I can access voicemail through the contact list which is how I found out that I had 6 VMs.

Any suggestions on what I can do to fix any or all three of the issues?

Open the settings for your visual voice mail and then clear all the cache and data from the app, after you do that open the application and turn on all the notification settings, you can also access the settings for your visual voice mail from the phone application, make sure that you turn on all the settings

Thanks, that worked.
