Best Answer: Short message service. From Wikipedia: Short Message Service (SMS) is the text communication service component of phone, web, or mobile communication systems, using standardized communications protocols that allow the exchange of short text messages between fixed line or mobile phone devices.
When youâre done with the text portion of the message, tap the Send Text button, and off it all goes. A simple text message is an SMS (short message service) message. When you add an attachment, youâre sending an MMS (multimedia messaging service) message.
