Hi - I just wanted to update you on some things I have learned (the hard way).
Visual Voice mail works on this unlocked phone. However, to get PREMIUM visual voice mail, that is a bit stickier.
If you already have a verizon phone with premium visual voice mail (i.e., you are paying 2.99 per month), and then you switch to the new phone by moving the sim card, the first time you get a voice mail, you will be prompted to load the voice mail software from the Samsung store, and all will be perfect. Verizon won't know what happened.
God forbid, you need to turn it off with Verizon - you will never get it back on again. I was getting a broken robo call that was coming in every few minutes. I decided to call verizon and temporarily disable vmail. BIG mistake.
Once verizon determines that your phone is not a verizon device, it will not make premium visual voice mail available to you again on the website or via the app itself.
I think the only way I could do this would be to reactivate my old HTC 10 (and pay $30 fee?), turn on visual voice mail and then take out the sim (and for another $30?) reactivate the Note 9.
However, after struggling with verizon for 2 weeks, I decided to try another service - Phone Fusion Visual voice mail... and I have to say, for $1.99 per month it is working ok so far. I'll need to wait a couple of months to see how it goes.
So the lesson here is to move FROM a phone line with premium visual voice mail...not to activate it on a new non-verizon device.
Good luck,
R
