In 1933 RCA Communications, New York introduced the first "telex" service.Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom.
Text messages may be sent over a cellular network, or may also be sent via an Internet connection.GSM was allowed in the United States and the radio frequencies were blocked and awarded to US "Carriers" to use US technology.Hence there is no "development" in the US in mobile messaging service.The GSM in the US had to use a frequency allocated for private communication services (PCS) – what the ITU frequency régime had blocked for DECT – Digital Enhanced Cordless Telecommunications – 1000-feet range picocell, but survived.American Personal Communications (APC), the first GSM carrier in America, provided the first text-messaging service in the United States.Sprint Telecommunications Venture, a partnership of Sprint Corp. made the initial phone-call to launch the network, calling Mayor Kurt Schmoke in Baltimore.
and three large cable-TV companies, owned 49 percent of APC. One factor in the slow take-up of SMS was that operators were slow to set up charging systems, especially for prepaid subscribers, and to eliminate billing fraud, which was possible by changing SMSC settings on individual handsets to use the SMSCs of other operators.
The term originally referred to messages sent using the Short Message Service (SMS).
It has grown beyond alphanumeric text to include multimedia messages (known as MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces ,sad faces ,and other icons).
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".
