I'll explain my situation and hopefully you guys can help me out. My dad (account holder) has an iPhone. My sister has an iPhone. My number is due for an upgrade, so I plan on buying the new iPhone. Will we have to make adjustments to our plan to accommodate the new iPhone being added to the Share Everything network? (I'm not asking data-wise, we will all manage our data together.) Or can I simply preorder it from Apple (or VZW), get it in the mail, activate it, and continue to use it without worrying about any plan adjustments or having to do anything through Verizon?
