The Samsung Galaxy S7 Active is an AT&T exclusive device. It doesn't have the radio hardware to work on the Verizon Wireless network. I highly doubt a version will be made available as an unlocked model and compatible with the Verizon Wireless network. Past history of the Active line is the basis for that reasoning.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
