Follow the link address it will explain how to put the sim in your phone.

On the right side of the phone (about half way down), there's a tiny little hole, and surrounding it is a little box. Get a paperclip (or the one Apple provides) and poke the hole. A little sim card tray will pop out.
It goes in there.

I put the sim card in the tray but it says NO SIM
