In recent events, I learned that some pagers only have receivers. How are discrete messages sent to these devices? How is it authenticated? How do they know the device got the message?

    They are receive only devices that work using radio signal. Messages are sent using a transmitter of some type. I understand this is a very basic description, I’m not an expert, just have an interest in telecommunications related things.
