I've been trying to get my iphone activated but can't because of it being a second hand phone?

I'm not quite sure what the issue is but if you turn it on and it isn't like allowing you to set it up as a new phone you may have to plug it into iTunes to wipe the phone and then you can set up as a new phone

If you bought the phone from someone with an unpaid phone bill, you might not be able to activate it.

It could also be stolen. The phone may have been disabled once the IMEI number was reported.
