The pager is like a portable secretary. Like a secretary, it tells you when you have to make a phone call, and tells the time.
Some pagers even have alarms that can be set to go off at any time.
Each pager has a different number, which looks just like a telephone number with seven digits. A caller punches in the number into a phone. After they have dialed the number, the caller enters the number where they are. Some pagers have message capability Return to top. Inside the pager is a tiny receiver, which picks up the numbers that have been dialed, just like a cell phone or a regular house phone.
