    GSM signal is a kind of mobile phone signal, so GSM jammer belongs to mobile phone jammer. If you only want to shield the GSM signal, you only need to choose a mobile cell phone jammer that will only interfere with the GSM signal of the device, but if you want to shield other mobile phone signals besides the GSM signal, such as 3G, 4G or even 5G signals, then I suggest you buy A mobile phone jammer for GSM 3G 4G 5G signals. If you want to shield other signals, it is recommended to use a mobile phone jammer with more antennas.
