cell phone disruptor jammer can help block the signal

There are many types of cell phone jammer on the market, so if you want to block cell phone signals over a large area, you're going to spend a lot of money on one of these devices. In order to buy expensive jamming equipment, you can buy one of these portable devices, especially if your main goal is to stop people nearby. In this case, I think a physical distance of around 5 meters is enough, especially when you're using it on a bus, when you want to keep people quiet for a few minutes, such a Cell Phone Disruptor Jammer would definitely help. You can try ali Express's phone mixer.

Mention should be made of outdated technology such as Blusnarfing. The word itself means using Bluetooth to hack into various mobile devices. Previously, it was rarely used due to its flaws: hackers had to place it within 10 meters (30 feet) of a target because it was in Bluetooth range. But now, as bluetooth's working range expands, it's becoming more and more popular. Sometimes pirates can even use very sensitive unidirectional antennas to attack remotely. However, it is very important to protect yourself from damage and Cell Phone Disruptor Jammer can effectively intercept surrounding WiFi networks and protect security.

But there are sometimes dangerous mobile apps that not only steal your money, but also collect your personal information. Typically, these applications need access to your navigation history, contact list, and the device's physical memory. In addition, they will try to obtain a license for unlimited Internet access. If you find that applications unrelated to Internet service require unlimited Internet access, try to avoid this, which is the main reason many office or business center meeting rooms use cell-phone signal jamming devices.
