I received to phone with a sim card preinstalled because I used an upgrade from a line that had a dumbphone activated on it. When I first turned on the phone it would not activate and the phone instructed me to call Verizon, I turned the phone off and turned it back on to see if it would activate and it did not and intsructed me to call VZW again, I did not feel like calling VZW at that time so I decided to use wifi to customize the to my liking with apps and put it through some paces. When I rebooted the phone a third time the phone activated but it still instructed me to call VZW to get it activated for some reason, 4G LTE dropped in and out for about 2 minutes and has been flawless ever since.
