I just set up my Samsung Galaxy J7 Crown phone that I purchased from QVC in February last year. Due to wi-fi outages at home I hesitated to try and activate it until that was fixed, and I had to as my LG phone was only being supported until the end of '19.
I use the visual voicemail, it's great. You can also do the usual dial in way if you want. My voicemail account transferred just fine, as did my phone number, and it activated in about a minute, a record for me and tracfones.
After reading the reviews on this phone I was reluctant even to try it, but after at least 4 android updates when I set it up it is up and running and no issues so far.
I love it. Beautiful display, fabulous camera, easy to use, and in settings I managed to get a nice large font, adjust everything to my own preferences. My screen is fine but I am not hard on phones. HTH!
