You're going to have to ask Ozeki.

A quick look at their site, has this example[^] using HTTP.

There's also the C# examples, which seems to be more flexible, here[^].

If you try to tell me "but I don't know C#!". I'm going to tell you you're wrong. C# is not that much different from VB.NET. There are also online converters that can convert sections of code for you and come up with a reasonably good translation.

Keep in mind, if you're putting a password into a URL to connect to the service, you should really NOT use that as you're sending a password in CLEAR TEXT over a network channel that can be intercepted at any point.

That makes a bit more sense.

Yes you CAN stop it. Buy a license to use the service.

Oh, and if is the actual code you're using, you're sending your password to use the service in CLEAR TEXT, meaning anyone with any kind of sniffer can see your password.

You sure you still want to use that service?
...problem is this that app not purchased then they use their by default sms some words like this is by send
You're using the free trial edition of the product, which appends the "nag" message to your texts.
SMS Gateway - Manual, Trial version limitations[^]

The simple answer is to purchase a license for the product instead of using the evaluation version.
