Verizon Note 4 n910v in Metro PCS help

[Mayrel2015]

Hello, I have a Samsung Galaxy Note 4 Verizon without contract, bought free of contract, I'm currently using on Verizon but I want to change to Metro PCS, as I read the note 4 on Verizon is free to manufacture, want to know what I should do Metro PCS in order to use it, set apart from the APN : Confuso:, because I get a message that I'm not using a line of Verizon, someone can guide me how to operate with data ?. Thanks and waiting for their aid.
