Like e-mail and voice mail, 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.

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.

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.

As of 2017, text messages are used by youth and adults for personal, family and social purposes and in business.

Governmental and non-governmental organizations use text messaging for communication between colleagues.

The Sprint venture was the largest single buyer at a government-run spectrum auction that raised $7.7 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.As with emailing, in the 2010s, the sending of short informal messages has become an accepted part of many cultures.This makes texting a quick and easy way to communicate with friends 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).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.In 1933 RCA Communications, New York introduced the first "telex" service.
