As we all know, different countries use different signal frequency standards. For example, in the United States and Canada, even the same 3G signal is different. This is why many people who buy interference devices have to wait a while before they can see the device sending. This is because after each cell phone jammer is purchased, we will fine-tune the signal frequency band according to the customer's region and country to ensure normal use. This is why interfering devices are usually customized rather than directly purchased and shipped.
Therefore, when choosing to purchase interference equipment, please confirm the signal frequency band of your location. Otherwise, after you purchase the device, the device may not work properly. This is why it is usually recommended to buy a local signal standard jammer when purchasing such equipment. So everyone should be patient when buying a cell phone scrambler and make sure that they can buy a jammer that can be used normally.
