  • Hello Angelina! It is true that 3G is used for video calls, but that can be done with 4G too, so a simple 3G jammer won’t block video calls. That generation of mobile communications provides really huge data transmission speed and that’s why it is possible to organize video streaming using that standard. 3G is widely used for hidden video surveillance because of those reasons too. Our SFC15 signal jammer is able to block 3G, but you can’t be sure that it will jam video calls, because they can be made on 4G too. 4G is the fastest mobile generation and it provides even better speeds than 3G. And that mobile standard may be used for making video calls. To block 4G you will need more advanced signal blocker because SFC15 will not block 4G because those mobile generations use different frequencies for broadcasting. 3G uses 2100 MHz and 4G uses frequencies around 875 MHz frequency band. But we at can provide you the device that will block 4G. To be sure that no one will be able to make video calls around you, you should try to block both 3G and 4G and this portable 3G/4G jamming device is able to achieve that. It will block not only 3G and 4G, but 2G as well. What advantages you will get? You will be able to block GSM and CDMA as well and it will block voice calls and text messages too. Also that signal blocker will prevent locating you with a cell tower triangulation. Thanks for your question, I hope I’ve managed to help.
