The phone will become blacklisted which prevents it from connecting to any networks. It would still function but not as a phone, you won't get 3G/4G either. This is to stop you from using it as a phone or selling it as a phone.

You will have to keep paying the contract, or it will eventually be considered stolen.

If you stop paying it does _not_ get you out of the contract or cancel the debt and you will likely find yourself receiving a court summons or have debt collectors calling on you.
