Short message service

Short Message Service (SMS) is a service available on most digital mobile phones that permits the sending of short messages (also known as text messages, or more colloquially SMSes, texts or even txts) between mobile phones, other handheld devices and even landline telephones. Other uses of text messaging can be for ordering ringtones, wallpapers and entering competitions. SMS is widely used for delivering premium content such as news alerts, financial information, logos and ringtones. Such messages are also known as premium-rated short messages (PSMS). The subscribers are charged extra for receiving this premium content, and the amount is typically split with the mobile network operator and the content provider (VASP) dividing the income either through revenue share or a fixed transport fee. Premium short messages are also increasingly being used for "real-world" services. For example, some vending machines now allow payment by sending a premium-rated short message, so that the cost of the item bought is added to the user's phone bill. A new type of 'free premium' or 'hybrid premium' content has emerged with the launch of text-service websites. These sites allow registered users to receive free text messages when items they are interested go on sale, or when new items are introduced. Some companies like WordTel Communication share their gateway among professionals to communicate with that via an Application Programming Interface (API) in order to have their software broadcast messages. The connection between their software and the gateway is established through Internet line. Because of the limited message lengths and tiny user interface of mobile phones, SMS users commonly make extensive use of abbreviations, particularly the use of numbers for words (for example, "4" in place of the word "for"), the omission of vowels, as in the phrase "txt msg", or the replacement of spaces with capitalization, such as "ThisIsVeryCool". To avoid the even more limited message lengths allowed when using Cyrillic or Greek letters, some Eastern Europeans use the Latin alphabet for their own language. Historically, this language developed out of shorthand used in chatrooms on the Internet, where users would abbreviate some words to allow a response to be typed more quickly. However, this became much more pronounced in SMS, where mobile phone users don't generally have access to a QWERTY keyboard as chatroom users did, and more effort is required to type each character. In Mandarin Chinese, numbers that sound similar to words are used in place of those words. For example, the numbers 520 in Chinese ("wu er ling") sound like the words for "I love you" ("wo ai ni"). The sequence 748 ("qi si ba") sounds like the curse for "drop dead". Predictive text software that attempts to guess words (AOL/Tegic Communications's T9 as well as iTAP) or letters (Eatoni's LetterWise) reduces the labor of time-consuming input. This makes abbreviations not only less necessary, but slower to type than regular words which are in the software's dictionary. However it does make the texts longer, often requiring the text message to be sent in multiple parts and therefore costing more to send. Website portals such as translit! have supported a community of users to help standardize this text speak by allowing users to submit translations, staking claim with their user handle, or to submit top messages and guess the lingo phrases. The international popularity of this portal resulted in late 2005 the publishing of the transl8it! dxNRE & glosRE (dictionary & glossary) as the worlds first, and most complete, SMS and text lingo book.
