I want to have an unlocked iphone 6. So I bought an unopened verizon iphone 6 from someone on Craigslist. It seems like I didn't do an important step --- take out the verizon sim card inside the phone before activating the phone... So now I got stuck on the page that ask for the verizon account holder's zip code and last 4 digit of ssn. What do I do now?
