I'm pretty sure the phone supports Verizon and CDMA because of the Chipset but as far as I know they don't activate it because Verizon and Sprint want extortion money to sell the phone on their network. The new CEO of Microsoft said they would no longer pay money to carriers just to sell their phones, this is one reason phone sales are down so much but another reason we now can get updates for windows 10 whenever we want. This is something the government needs to take care of, I thought we were soposta be able to use unlocked phones on any carrier but Verizon is still using cdma for authentication and the LTE Service is GSM or universal so they are really trying hard not to allow unlocked phone on their network. Verizon can use LTE for authentication but they doe this to prevent unlocked phones on their network.
