SMS Centre is a 32 bit (Windows 95/98/Me/NT4/2000/XP) client for sending SMS Messages to a mobile phone on any of the four major UK Network networks or SMS/Paging Messages to any worldwide network whose dial in service centre supports the TAP protocol. SMS Centre exposes a programming interface (Programmers API) to enable third-party programs to process messages and then use SMS Centre remotely to deliver them by Mobile Phone or Pager world-wide. SMS Centre has a Message Queue facility and it is possible to queue multiple messages to either a single or to multiple providers. SMS Centre will work out which network to send each message to and dial accordingly
