Why can't my 4G jammer make video calls on my iPhone 6S?

I recently purchased a 4G jammer and it doesn't seem to be working. I'm sure my device blocks all video calls around me, but it doesn't. what should I do?


You're right that most video calls use a 3G connection. If you block this connection, you will not be able to make video calls. dojammer can predict several reasons why your 3G blocker won't work. The first: it might be broken, but I recommend you keep an eye on it anyway. The second reason could be the great distance between you and your target. In this case, all you have to do is check the range of the device and maintain the distance between you and the target. There may also be base stations nearby, so the interference radius will be smaller.
These guys can also make video calls using a non-3G connection. You know, they can use a Wi-Fi internet connection for their purposes. There are many apps that can help you achieve this. For example, one of them is FaceTime. You can use it to make video calls over the Internet on your iOS device. 3G jammers don't work on Wi-Fi because their frequencies don't match. 3G uses 2100 MHz and Wi-Fi - 2400 MHz.
Another option is that they use FaceTime with a 4G connection. AT&T officially supports FaceTime, and the app uses a 4G LTE mobile internet connection. Verizon also offers a 4G internet connection, so it might work for its subscribers as well. 4G LTE uses 720-785 MHz, so 4G jammers won't affect it. In this case, it is better to use a universal anti-video call jammer. 3G, 4G and Wi-Fi will be blocked. Therefore, there will be no video calls within 15 meters of you.
