In Canada, Mexico and the United States, PCS are provided in the "1900 MHz band" (specifically 1850-1990 MHz). This frequency band was designated by the United States FCC and Industry Canada to be used for new wireless services to alleviate capacity caps inherent in the original AMPS and D-AMPS cellular networks in the "850 MHz band" (specifically 800-894 MHz). These frequency bands are particular to North America and other frequency bands may be designated in other regions. Therefore, this frequency jammer is only suitable for use in North America. Before choosing this type of jammer, please pay attention to your area.
