I got an IPad 3 with Verizon 4G, and when I tried adding device to my account on Verizon's website and it needed my "Sim Card number", I found out it was the ICCID # in the about/general/settings.
I entered it, and it says number could not be accepted. Is that the right number to enter? I'm new to the IPad, could it be locked in some way? Help!!! well appreciated
