Hello.

Status 9 is Reserved value in the SMPP specification. I think you need to ask your SMPP provider about meaning of this status code.

Who is vendor of this SMSC?

Hi Steve,

You can use sequence number when you send SubmitSm object using SubmitAsync and check its response in the event evSubmitComplete by this number. You need to add a hash into you program where the key will be a sequence number and the value will be a SubmitSm object.

Thank you for your message.
I turned security level to MEDIUM.
Please try to download once again.

ServiceType property has been added.
Please download http://www.inetlab.ru/Download/SmppClient.zip

I didn't measure the speed. I think it depends on SMSC only.

When did you get this message?
Can you send me log file?

Please try version 1.3.0.
I've added method SubmitAsync.

I've just checked the link http://www.shareit.com/product.html?car ... =300131821
and it works.
Could you check above link once again? Otherwise I can try to place this product at Plimus.

try this code
EnquireLinkResp res = client.EnquireLink();
if (res.Status != CommandStatus.ESME_ROK)
{
// reconnect with SMSC
}

could you send me whole log like in SmppClientDemo. I need to check bytes received with DeliverySM
