Phone can't dial out
Mr. Wen, a citizen who lives near Shuanggang, recently discovered that standing on his balcony to make mobile phone calls is always not smooth, either unable to make calls, or the calls are intermittent. After changing different mobile phones successively and unable to improve, Mr. Wen complained to the operator.

The "mobile phone jammer" in the gas station works continuously on weekdays to ensure that the gas station will not cause fire and explosion hazards due to the use of mobile phones, but Mr. Wen's home, a few hundred meters away from the gas station, was also disturbed.
