Text of SMS message can consist of alphanumeric characters. The maximum size of the message in standard GSM is 140 byte. Thus, at usage of the 7-bit coding (the Latin alphabet and digits) it is possible to send messages in length to 160 characters.
At usage of the 8-bit coding (German, French language) it is possible to send messages in length to 140 characters. For support of other national alphabets (Chinese, Arabian, Russian, etc.) coding UTF-16 is used 2-bite. Thus, the sms written by Cyrillic cannot exceed 70 signs. Technology of SMS is supported by the main cellular networks (GSM, NMT, D-AMPS, CDMA). Also on phones it is possible to send sms from the Internet and other networks. Using special programs, universal SMS forms, and also it is direct gateway servers of transportable operators
