I work for a cell phone company and I need to write a VB program to send a standard text message to multiple phones every day. I plan to connect to our SMSC gateway using SMPP to send the text messages. I saw a mention of devshock.com, but their website is down for development. Does anyone know an alternate site that I can get some of their free code or another reliable source for free code that will allow me to communicate with the SMSC using SMPP to send text messages? I was able to send a few messages using SmtpClient, as if they were emails, but it adds the return email address, which would make the message too long.
