Short Message Service
     
         (SMS) A message service offered by the {GSM}
        digital {cellular telephone} system.
     
        Using SMS, a short alphanumeric message (160 alphanumeric
        characters) can be sent to a mobile phone to be displayed
        there, much like in an {alphanumeric pager} system.  The
        message is buffered by the GSM network until the phone becomes
        active.
