The truth is, you can't always be close to family or friends, but no matter how close you are to your phone, you can be close to them and communicate with them through your phone. Of course, there are some devices, Block 800 Numbers From Cell Phone is part of them. There are many types of cell phone jammers on the market, so if you want to block cell phone signals in a large area, you have to spend a lot of money to buy one of them.

So it seems like a high licence fee is required to be a practical station. Also, for Block 800 Numbers From Cell Phone, the license fee is borne by the theater where the device is installed. It's impossible for theaters to pay the same licensing fees as cell phone carriers. On the other hand, in the case of a test station, the license plate fee is 500 yen per vehicle per year. "Therefore, we consulted the Ministry of General Affairs and Transportation to temporarily handle it as an experimental station. Currently, we are requesting the Ministry of General Affairs and Transportation to develop a frame phone that is different from the experimental station." and base station.
