Hello, Anton
Although the common frequency band of cell phone jammer is GSM CDMA 3G 4G LTE, but different countries adopt different frequencies.
For example, the frequency used in the United States is as follows:
4G LTE 725-770MHz
4G 790-862Mhz
CDMA 850-894MHz
GSM 925-960MHz
3G 2110-2170MHz
4G 2300-2400MHz
4G 2620-2690Mhz
Compared with North America, European countries use different benchmarks, so it's important to determine which country you're in before you know what frequency to use.
