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.
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.
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 phones, tablets, desktops/laptops, or other devices.
Text messages may be sent over a cellular network, or may also be sent via an Internet connection.
American Personal Communications (APC), the first GSM carrier in America, provided the first text-messaging service in the United States.
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.
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.
