I recently purchased an unlocked iPhone Xs Max and the Apple store moved my SIM chip from my old Android phone into my new phone and I'm connected to Verizon.
I'm getting (and making) calls and messages just fine. Verizon has recognized the change because my account shows the correct phone model listed for my number.
But when I get a voice mail, I receive a notification from Verizon in the form of a string of gibberish characters that shows up in the Verizon Messages app. (iOS thinks it is Junk or Spam, BTW.)
My plan says that I am supposed to get free visual voice mail (basic) on my iPhone.
How do I get that to work? I've read the instructions about going through "setup" on my voicemail app, but there IS no setup option since my voice mail is already set up.
