Can you buy an iPhone in one go, and never pay for it again?

I was just wondering whether you can just buy it at a shop (and pay a huge amount of money, of course!) and then just never pay again.

Yes you can you pay for it full price then its yours

Yes you can buy one straight out in cash all you then have to do is put your sim card into. It so long as the phone is open for your sim card… Unblocked…
I recently bought myself a Samsung galaxy note 2 android paying the full money up front and just put my o2 sim card in…

Yes you can buy it outright then its yours

Of course, many do this.

Yes, you can purchase an iPhone for full price at a store or from a cellular provider.

However, if you want cellular service on the iPhone, you would have to pay a monthly fee.
