Issue: Unable to send SMS message from the Application written in Visual Basic.
Cause: SMS SDK is written in C# thus it does not support Visual Basic.
Also, sending SMS message was not supported by the phone number that was initially used.
Resolution: Wrote SMS send function in C# and added it to Visual Basic project as a module.
Also, a toll-free number that can send & receive SMS message was bought.
ACS doesn’t support visual basic directly, so the recommend option is to just using REST APIs.
