Early Text Messager is a term used to describe two different communication technologies that were popular in the late 20th century. The first is PAGER, which was a device that allowed people to receive short messages from a central location. The second is Telex, which was a teleprinter-based system that allowed users to send and receive text messages over telephone lines. Both of these technologies were used extensively in the early days of text messaging, before the advent of mobile phones.
