I just got a new galaxy 7s, and I am trying to move my phone number from, my galaxy 4s, when I tried to follow the directions on myverizon I got a message that my sim card is not correct.
Yes, the phones have 2 different SIM sizes. You can go to a corporate Verizon store and get one free or call CS and they will send you one for free. The S4 uses a micro sim and the S7 uses a smaller nano sim.
