Diafaan SMS Server is a powerful and easy to use SMS gateway for 3G/GSM modems and SMPP SMS providers. It is targeted at professional users, companies that are 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, Hypermedia or Cinterion. Another option is to use an online SMS provider that supports the SMPP protocol or 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 multi-user 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 SMS messaging. Power users will appreciate the C# or Visual Basic.NET scripting capabilities. The full edition of Diafaan SMS Server has no limits on the number of GSM modems, SMPP accounts or Clickatell accounts and also no limits on the number of HTTP, Email, or SQL interfaces used. It has a 30-day trial period and works without annoying ad messages or other limitations during the trial.
