I bought a factory unlocked Samsung S8 from Best Buy to use on Verizon where I have been customer for 16 years. I bought unlocked because it was cheaper than buying a Verizon Locked phone. The phone for the most part works fine but I don't get any notifications that I am getting voicemail's. I have to randomly call every couple of hours to see if I have gotten a voicemail. I can check it fine. I called support and was told it is not their problem that I bought a non Verizon phone and they cannot send me the basic voicemail app it has to come pre-installed on phones locked for Verizon that the only thing I can do is buy another phone from Verizon or deal with it. I am seriously thinking of leaving Verizon over this. I have to get notifications that I have emails.
