Prior to the development of mobile phones, individuals communicated through the mail, telegrams, and landline telephones. However, long before these things existed, humans communicated by means such as smoke signals and the dispatching of messengers from one region to another.
Throughout history, humans have always had a manner of communicating. Prior to the introduction of cellphones, the following methods of communication were utilised.
Smoke signals — communication with people on faraway lands would occur via smoke signals that could be deciphered by both senders and recipients.
Messengers — there was also a time in history when messages were carried on horseback or on foot from one region to another.
Writing letters on paper with pencils or pens was a widespread practise prior to the mass manufacture of mobile phones.
Telegrams — the telegraph was a mechanism used to type and transmit messages from one area to another. It could only transmit a limited number of words in a given time frame.
Before the development of mobile phones, humans would communicate through landline phones. Currently utilised less commonly, these are essentially telephones that are wired together and located in specific locations.
