How to block van eck phreaking on a mobile device

Anyone one know how to block someone from van eck phreaking my cell phone? I think its coming from a local dirtbox

It takes lot of equipment to perform that. Not sure if you really are experiencing van eck phreaking. Anyway you can create a faraday cage to stop it.

Can u give me a list of the equipment and where i can buy it

You can google faraday cage on google and it will show where to buy based on your location
