Now that Verizon is asking for full price for a phone I think craigslist used phone market will be hotter. My question is can you take a used Note 4 from say AT+T or T mobile and bring it to Verizon network? I know AT+T or T mobile are GSM carries but does the Note 4 have a CDMA radio inside already that can be turned on. I am sure a Sprint Note 4 would work too but AT+T or T mobile ones I am not sure of functionality. Thanks for the help.
