[Q] Verizon Moto G as a Test Device topic

I purchased a used Moto G to be used as a test device on wireless networks, without any mobile plan. I'm brand new to Android so I'm not sure where to begin. As it is right now, I've got a Verizon screen that wants to validate the device. I can't get past that. The phone is unlocked, but I'm unclear about how to move forward.

I apologize for not even knowing what to search for since I assume this question has been answered before.

Thanks
