A:AnswerIf Verizon is anything like ATT you most likely will not be able to use wifi calling. You need to have HD Voice and that's not included with the unlocked version, it's a feature at least with ATT that only comes with their branded phones.
A:AnswerI think it is new. However it was a customer return. It had been locked to a carrier and sold to me as unlocked. It cost me $60 in Belize to get it unlocked for use.
A:AnswerI'm on Virgin Mobile. You need a SIM card from them to make it work. Once you install the card ---call Virgin to activate your service. Good luck.
A:AnswerAny carrier will need the device number to get it into their system. The unlocked version has several missing features like no WiFi calling that you might want.
You'll be better off just buying it from the provider you're going to use in the first place.
