NowSMS will do this automatically for long messages.

However, the SMPP specification is not specific about long message encoding, and different SMPP servers expect different encoding.

The default setting for NowSMS is to use UDH (User Data Header), with standard 8-bit text encoding.

Some SMPP servers require 7-bit packed encoding when UDH is used. If text is garbled when you send a long message, there is a setting under advanced settings for the SMPP connection “Encode long messages with 7-bit packed encoding" that will enable this encoding.

Other SMPP servers expect SMPP TLV parameters to be used for segmentation. There is a setting under advanced settings for the SMPP connection “Use TLV parameters for port numbers and segmentation” that will enable this encoding.

Still other SMPP servers want the entire long message in one submission using the message_payload parameter, and the SMPP server will perform the segmentation. There is a setting under advanced settings for the SMPP connection “Use WDP Adaptation for WAP Push and MMS” that will enable this encoding.

If you are having problems with long messages, try the following different settings combinations under the Advanced settings for the SMPP connection, as one should work:



1.) UDH with 8-bit text:
“Encode long messages with 7-bit packed encoding” – NOT CHECKED
“Use TLV parameters for port numbers and segmentation” – NOT CHECKED
“Use WDP Adaptation for WAP Push and MMS” – NOT CHECKED

2.) UDH with 7-bit text:
“Encode long messages with 7-bit packed encoding” – CHECKED
“Use TLV parameters for port numbers and segmentation” – NOT CHECKED
“Use WDP Adaptation for WAP Push and MMS” – NOT CHECKED

3.) TLV segmentation parameters:
“Encode long messages with 7-bit packed encoding” – NOT CHECKED
“Use TLV parameters for port numbers and segmentation” – CHECKED
“Use WDP Adaptation for WAP Push and MMS” – NOT CHECKED

4.) Entire long message in message_payload parameter:

“Encode long messages with 7-bit packed encoding” – NOT CHECKED
“Use TLV parameters for port numbers and segmentation” – NOT CHECKED
“Use WDP Adaptation for WAP Push and MMS” – CHECKED

If your SMPP provider can support long messages, at least one of these options should work.

I assume you are using NowSMS because you have posted in an area marked Product Support Only. If your question does not involve NowSMS, I would encourage you to use the search function here as I am sure there are posts that provide information on UDH segmentation. You can also post general questions in the unsupported area at http://support.nowsms.com/discus/messages/12/12.html
