What is the role of this Cell Phone Jammer ? The reporter bargained and bought a portable Block A Number On Samsung Cell Phone with the smallest coverage at the price of 120 yuan. This cell phone jammer is about the size of a typical candy bar phone on the market, but about twice as thick as a cell phone. The all-metal casing has 3 antennas on the top, which can interfere with the signals of China Mobile, China Unicom, PHS, and even the recent 3G mobile phones.
