This is the link I learned to send multi-part SMS in PDU, a very good tutorial.But how if I want to send Unicode SMS? From one of the comment from the developer:
Yes, the DCS should be
0×08and the UDL should be in octets (which ends up being 1 + UDHL + 2 * number of characters). Also you don’t have to insert padding as in the GSM-7 case. I know you’ve already managed to send UCS-2 (not concatenated) messages, so it must be something small you’re missing. If you wish you can post your PDUs so I can check…Jeroen
it seems I do not need to add 1 bit padding for the message. But if I using the same UDH format as normal SMS it will just show me unknown characters. Can anyone give me some hints?
This is the sample PDU with chinese character but should be with errors..

Thanks.
Your DCS is wrong.
0041000B910661345542F6000*0*A00500030302010008044F60597D
should be
0041000B910661345542F6000*8*A00500030302010008044F60597D
for a DCS of 0x08 = UCS-2 encoding.
