Hi, SMSLib for .NET is actually a Java application which has been converted to .NET with IKVM. You can read more here: http://smslib.org/doc/smslib/dotnet/
The source code is recently moved here: https://github.com/smslib/smslib-v3 The "string index out of range" are (usually) thrown when there are messages that cannot be read by SMSLib - mms variants for example. Regarding the outbound issue, can you post an example? What message are you trying to send? -- You received this message because you are subscribed to the Google Groups "SMSLib Discussion Group" group.
