Definition[]
A pager (sometimes called a beeper) is a simple personal telecommunications device for short messages.
Overview[]
A one-way numeric pager can only receive a message consisting of a few digits, typically a phone number that the user is then expected to call. Alphanumeric pagers are also available, and two-way ones can send email or SMS messages as well as receiving.
Until the popular adoption of mobile phones in the late 1990s, pagers filled the role of common personal and mobile communications. Since 2007, pagers have fallen into obsolescence and are preserved only by niche markets consisting largely of emergency service personnel, medical personnel, and information technology support staff.
