What does "One Time Charges" mean?

Are you trying to set up a plan without a contract? If so, that means you're paying a monthly $47 for that plan, but have to pay just once that large lump sum for the phone itself. If you contract your phone, then your monthly payment goes higher, but then you don't pay that lump sum for the phone - you pay for your phone as you're paying for your plan. Make sense?
