Verizon and Google are holding a promotion where you can get 2GB of free data simply by using Android Pay in supported stores. As usual, things with Verizon aren't always so straight forward. So let me explain it in further detail. If you use Android Pay in a supported store once, then you get 1GB of free data. You'll have to use it two more times(again, in supported stores) if you wanted to get the second GB of free data.
