I recently upgraded to the iPhone X. The upgrade was smooth with one exception. The voicemail is not working correctly. I do not get any badge alert on the voicemail when I have a new voicemail. Instead, I get a garbled text from Verizon with no real content. The visual voicemail doesn't appear anywhere on the device. When I go to the voicemail icon I don't get the option to set up voicemail, just a button that says call voicemail. I have searched the settings and can't find any place to set up the voicemail, nor have I had any luck with the forums or information on Verizon's website. I have reset network settings and restarted my phone. What else can I try?
