Happy birthday SMS texting 20 years today.
SMS messaging was used for the first time on 3 December 1992, when Neil Papworth, a 22-year-old test engineer for Sema Group in the UK (now Airwide Solutions), used a personal computer to send the text message “Merry Christmas” via the Vodafone network to the phone of Richard Jarvis.
