Free Cell Phone Robocall Blocker

Now more and more schools will install Free Cell Phone Robocall Blocker in dormitories to prevent college students from staying up at night to surf the Internet and play mobile phones all night. cell phone jammer is to interfere with the mobile phone to receive the normal frequency from the base station through its own frequency, so that the mobile phone mistakenly thinks that the signal sent by the mobile phone jammer is the signal of the base station, so the mobile phone and the base station lose contact, and the mobile phone cannot be used normally. . Our dormitory is open day and night, the classroom is the same, the library is even worse, the use of our own network is also blocked, and people are asked to check the materials to study? The school leader's three-shot decision is really fucking awesome. The signal is only better at 12 o'clock after class, but you fucking want to eat. It turns out that the school opened it up so that we could pay him the usual good intentions. It's to let us save some traffic and eat more.

Check for yourself whether only the signal of Telecom has become weak, or the signals of China Mobile, China Unicom, and Telecom are all weak. If only one of them becomes weak, it may be a problem of the operator. Now the Free Cell Phone Robocall Blocker is full frequency band, it can block all 2G 3G 4G signals and 2.4G WIFI signals under the three operators of China Mobile, China Unicom and China Telecom. If the Wi-Fi and the mobile phone signals of the three major operators are all weakened, it may be that a mobile phone jammer is installed. If this is the case, only install a cell phone signal amplifier near the place where the cell phone signal jammer is used to increase the cell phone signal. When the cell phone signal becomes stronger, the cell phone jammer is more difficult to block.
