How much does it cost to disconnect a line at sprint because it got stolen? - 1

Okay I was at school and somebody stole my other iPhone in the locker room! Should I just call sprint and tell them that it got stolen and to disconnect the line? What should I do? I'm so mad! And I think I have a idea of who stole it!

First off, you should file a police report over the phone being stolen. Second, you can call Sprint and have the phone taken out of service permanently, for no charge. If you find it, you can get it restored as well.

Need to end my sprint contract but can't seem to find how much it will cost any rough ideas
