What is pager?

Answer 1

A pager is a device which was commonly used by businessmen before cellular phones became common. They were small electronic devices which were often clipped to the belt. If the owner was wanted, the pager's phone number could be called. Once connected, the remote party could enter a short message (usually, only numbers were accepted), and this short string would be delivered through the then-young cell network. The pager owner would then act accordingly. In many cases, a page would be sent a phone number, and the recipient would then find a phone and call that number, though uses did vary somewhat. Pagers were cheaper to make, buy, and service, and also could not be as easily misused by an employee at an employer's expense. In some cases, pagers are still used, especially in companies which do not allow cell phones.
