Why mobile phone jammers are illegal in most countries?
I am a fun of mobile phone jammers, I bought the mobile phone jammers from a mobile phone jammer manufacturer—Beijing Signal Knight—www.wirelessphonejammer.com, I bought a pocket size mobile phone jammer SK-16A and a medium power mobile phone jammer SK-3. They are very good, and help me to bolck the annoying phone calls in the Lib, Lab, meeting room, and hospital. But there is a problem, someone told me it is illegal in most countries, could you tell me the reason? Why i can not use the mobile phone jammer? I think it will be very helpful for me.
