Can anyone kindly explain how to send a concatenated WAP PUSH SMS? I can send an SI that spans just one message, but I haven't figured out how to send one that spans multiple messages

A:
If you send a WAP Push message with a SMS Bearer, you've got a SMS with a User Data Header. This User Data Header looks like 0605040B8423F0 and contains so to say source and destination port for the WAP Push App in your phone. 0B84 is the destination port number (2948), 23F0 is the source port number (9200).
To send a WAP Push longer than 134 Bytes you have to add a Concatenation Header to the UDH, the UDH will then look like
0B00033F020105040B8423F0 for the first SMS and
0B00033F020205040B8423F0 for the second SMS
Split the remaining Wap-Push data in 129 Byte Chunks and append them to the UDH.
The glory details are part of the 3GPP Specification 23.040 found at http://www.3gpp.org/ftp/Specs/html-info/23040.htm
