Our online glossary is here to help you make sense of the terminology used in the cell phone industry.

What is "SMS"?

SMS stands for Short Message Service and is a standard used on mobile phones that allows for brief text based messages to be sent from one mobile phone to another. The basic SMS is 160 characters in length, but through the use of concatenated SMS, longer messages can be sent. At this time, messages can typically be sent from a given mobile phone to another on virtually any other network in the world, though that was not always the case. Concatenated SMS messages and those sent to users on networks in foreign countries generally cost more to send.
