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.

The Sprint venture was the largest single buyer at a government-run spectrum auction that raised .7 billion in 2005 for PCS licenses. SMS is available on a wide range of networks, including 3G networks.

APC operated under the brand name of Sprint Spectrum and launched its service on November 15, 1995 in Washington, D. However, not all text-messaging systems use SMS; some notable alternate implementations of the concept include J-Phone's Sky Mail and NTT Docomo's Short Mail, both in Japan.

In 1933, the German Reichspost (Reich postal service) introduced the first "telex" service.

Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom.

Texting is also used to communicate very brief messages, such as informing someone that you will be late or reminding a friend or colleague about a meeting.

As with e-mail, informality and brevity have become an accepted part of text messaging.

Governmental and non-governmental organizations use text messaging for communication between colleagues.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.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.text messaging was the most widely used mobile data service, with 74% of all mobile phone users worldwide, or 2.4 billion out of 3.3 billion phone subscribers, at the end of 2007 being active users of the Short Message Service.
