IPhone 5s activation help

What happens when you try to activate the phone? Are you seeing an error? Here is a support document to be used if you are experiencing a problem with activation. If you can't activate your iPhone - Apple Support

I'm sorry, what does that mean? The link I gave you is the Apple Support document with troubleshooting steps for trouble activating. If you do not wish to use those steps, that is up to you. I'm not sure what an itune is going to get you.

Then follow the steps in the support link I provided.
