Can I online order a phone (contract upgrade) then sell it unopened?

[stephens24]

Ok, this is what I'm thinking, tell me if this would work or bad idea etc......

I currently have iphone 5 and contract is up.... Thinking of buying unlocked 2014 moto x $500..... So to make that up....sell my iphone 5 (prob for a couple hundred) then use that couple hundred and order online a iphone 6......then when it arrives leave it unopened and sell it for prob cost of moto x and then some....then just activate moto x.

Is this just a terrible idea? Can I sell the 6 unopened with doing anything about my sim? (Since it's in the iphone 5)

Is it illegal? Would you do it, if strapped for cash? Thanks for the help.

If you buy that phone under contract/subsidy, the person you sell it to will not be able to register/use it until the entire cost is paid in full.
