I'm trying to send a binary SMS to a mobile via the SMPP interface of nowSMS.
For the sending of the SMS I need to use the TransactionMessageMode defined in SMPPv3.4 spec.

I know that the message mode is defined by setting the esm_class parameter according to SMPPv3.4 spec.

So I have two questions:

- First of all, I'd like to know if selecting TransactionMessageMode is supported in nowSMS?
- Secondly how can the esm_class be set in the web_GUI of nowSMS for sending binary messages?

Hi Alex,

No, we do not support the "transaction message mode" option.

It is actually more involved than just setting the ems_class parameter.

It also requires that we use the data_sm operation instead of submit_sm (currently we use submit_sm for everything unless WDP Adaptation is used, in which case we send WAP Push messages using data_sm).

And there is also an issue that the SMSC does not acknowledge message receipt until the message is either delivered (or times out? the spec is not clear on this). And that could be an issue, as well, as currently we require a response from the SMSC before submitting the next message. (Although this limitation will be removed in the next major release, where we will support multiple simultaneous outstanding transactions with the same SMSC.)

I'd like to find out more about your application to see if we might be able to suggest some alternatives. Or we could explore making modifications to support this.

What is your motivation for using transaction mode? Are you primarily interested in getting back delivery receipts? Or is it a non-delivery timeout issue?
