Radiolinja became the first network to offer a commercial person-to-person SMS text messaging service in 1994.
When Radiolinja's domestic competitor, Telecom Finland (now part of Telia Sonera) also launched SMS text messaging in 1995 and the two networks offered cross-network SMS functionality, Finland became the first nation where SMS text messaging was offered on a competitive as well as on a commercial basis.
Sitting at a typewriter at home, Hillebrand typed out random sentences and counted every letter, number, punctuation, and space.
Almost every time, the messages contained fewer than 160 characters, thus giving the basis for the limit one could type via text messaging.
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 permits, for example, sending simple graphs as text.
This was part of ISDN (Integrated Services Digital Network) and since GSM is based on this, made its way to the mobile phone.
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.
Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom.Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone.The possibility of doing something is one thing, implementing it another, but systems existed from 1988 that sent SMS messages to mobile phones usually messaging from one mobile phone to another mobile phone.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 sender of a text message is commonly referred to as a "texter".E-mail messaging from phones, as popularized by NTT Docomo's i-mode and the RIM Black Berry, also typically use standard mail protocols such as SMTP over TCP/IP.
