Diafaan SMS Server is an easy to use tool to turn a GSM or 3G modem into a full-featured SMS gateway. It is designed for professional users, looking for an easy way to integrate two-way SMS into their IT system.

After installation, the program lets you search for a 3G or GSM modem on your computer. Supported GSM modems include USB dongles, serial port modems and TCP/IP modems from companies like Huawei, ZTE, Wavecom, Siemens, Sierra Wireless or Cinterion. Another option is the Clickatell SMS service to send messages over an Internet connection.

The HTTP API lets you send and receive SMS messages from a browser or custom application and also adds a user friendly web application to manage SMS messages from any modern browser. You can setup an email interface that supports SMTP and POP and offers excellent integration with Microsoft Exchange. Or you can connect to an SQL database and send messages by simply adding records to the database, also an ideal solution for bulk messaging.

The light edition of Diafaan SMS Server supports one GSM modem or Clickatell account and one HTTP, Email, or SQL interface. It has a 30-day trial period and works without annoying ad messages or other limitations during the trial.
