The possibility of doing something is one thing, implementing it another, but systems existed from 1988 that sent SMS messages to mobile phones (compare ND-NOTIS). Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone. This was part of ISDN ( Integrated Services Digital Network) and since GSM is based on this, it made its way to the mobile phone. Under SS7, it is a "state" with a 160 character data, coded in the ITU-T "T.56" text format, that has a "sequence lead in" to determine different language codes and may have special character codes that permit, for example, sending simple graphs as text. SMS forms an integral part of Signalling System No. It was further developed under the leadership of Kevin Holley and Ian Harris (see Short Message Service). The first technical solution evolved in a GSM subgroup under the leadership of Finn Trosby. With Bernard Ghillebaert of France Télécom, he developed a proposal for the GSM (Groupe Spécial Mobile) meeting in February 1985 in Oslo. Almost every time, the messages contained fewer than 160 characters, thus giving the basis for the limit one could type via text messaging.
Sitting at a typewriter at home, Hillebrand typed out random sentences and counted every letter, number, punctuation, and space. Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom. The University of Hawaii began using radio to send digital information as early as 1971, using ALOHAnet. In 1933, the German Reichspost ( Reich postal service) introduced the first " telex" service. In the late 19th century, the wireless telegraphy was developed using radio waves. The electrical telegraph systems, developed in the early 19th century, used simple electrical signals to send text messages. The sender of a text message is commonly referred to as a "texter". It may simply be referred to as a "text" in North America, the United Kingdom, Australia, New Zealand, and the Philippines, an "SMS" in most of mainland Europe, or an "MMS" or "SMS" in the Middle East, Africa, and Asia. The service is referred to by different colloquialisms depending on the region. 5.5.2 Influence on perceptions of the student.Advertisers and service providers use direct text marketing to send messages to mobile users about promotions, payment due dates, and other notifications instead of using postal mail, email, or voicemail. Text messages can also be used to interact with automated systems, for example, to order products or services from e-commerce websites, or to participate in online contests.

Like e-mail and voicemail and unlike calls (in which the caller hopes to speak directly with the recipient), texting does not require the caller and recipient to both be free at the same moment this permits communication even between busy individuals. This makes texting a quick and easy way to communicate with friends, family and colleagues, including in contexts where a call would be impolite or inappropriate (e.g., calling very late at night or when one knows the other person is busy with family or work activities). In the 2010s, the sending of short informal messages became an accepted part of many cultures, as happened earlier with emailing. Governmental and non-governmental organizations use text messaging for communication between colleagues. Text messages are used for personal, family, business and social purposes. It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji ( happy faces, sad faces, and other icons), and instant messenger applications (usually the term is used when on mobile devices). The term originally referred to messages sent using the Short Message Service (SMS). Text messages may be sent over a cellular network, or may also be sent via an Internet connection. Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/ laptops, or another type of compatible computer. A text message using SMS - the 160 character limit led to the abbreviations of " SMS language"
