SMS messaging was first used in December 1992, when Neil Papworth, a 22-year-old test engineer for Sema Group, a US company, (now Airwide Solutions), used a personal computer to send the text message "Merry Christmas" via the Vodafone network to the phone of Richard Jarvis.
Standard SMS messaging is limited to 160 characters of the English alphabet. Initial growth of text messaging was slow, with customers in 1995 sending on average only 0.4 messages per network operator (e.g. MTC, Leo, Switch) customer per month. One factor in the slow take-up of SMS was that operators were slow to set up charging systems, especially for prepaid subscribers, and eliminate billing fraud.
Today, text messaging is 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 end of 2007 being active users of the Short Message Service. In countries such as Finland, Sweden and Norway, over 85% of the population use SMS. The European average is about 80%, and North America is rapidly catching up with over 60% active users of SMS by end of 2008. The largest average usage of the service by mobile phone subscribers is in the Philippines, with an average of 27 texts sent per day by subscriber.
In 2000 17 billion SMSes were sent, 2001, 250 billion and in 2004, 500 billion.
