So, I've got this new iPad 3 with 4 LTE capability from Verizon (but bought through Apple) and in setting up the data plan it asks for a credit card number and billing address along with the devices cellular number. I don't have a cellular number. Under Settings, General, About, it says cellular number unknown. I guess this means I have to call Verizon Wireless to have them set up the account? Is this correct? Any suggestions are appreciated.
