Yes, but it comes with a price.
A cell phone detector is a technological device that detects the presence and existence of cell phones in an area, like a classroom or worship place, or within a specified range of operation. The operator of this device can record a voice message or write a customized text message that will be sent to every phone detected. The authorities use them to clear out all unwanted things on important events and places. A single device can cost several hundred dollars or more.
