Short Message Service (SMS) language, textism, or textese^[a] is the abbreviated language and slang commonly used in the late 1990s and early 2000s with mobile phone text messaging, and occasionally through Internet-based communication such as email and instant messaging.^[1]

Features of early mobile phone messaging encouraged users to use abbreviations. 2G technology made text entry difficult, requiring multiple key presses on a small keypad to generate each letter, and messages were generally limited to 160 characters (or 1280 bits). Additionally, SMS language made text messages quicker to type, while also avoiding additional charges from mobile network providers for lengthy messages exceeding 160 characters.
