How to send Multi-part unicoded SMS using At Commands And PDU-Submit Not with Text-Mode?

Question

In my project, I want to send a unicoded text(UTF-8) SMS message through PDU-Submit. I've been searching a lot but all answers using Text-Mode and not PDU-Submit command, therefore I can't send multipart SMS. I want to have a solution for multi-part unicode messages.

Finally I have found the answer and use it.my program works fine. Sending a Concatenated(Multi-Part) SMS in Unicode Format Using PDU, is the same sending a simple septet-character SMS using AT+CMGS Command except you must set the DCS byte to 08.You can earn more Info on these threads:

You can send SMS messages with the AT+CMGS command in PDU mode (enable with AT+CMGF=0). The syntax (for pdu mode) is

AT+CMGS=<length><CR>
PDU is given<ctrl-Z/ESC>

I do not know if you are supposed to split into multipart yourself and send each part separately or if this command does that for you. I think maybe the latter, the description of the command says

Execution command sends message from a TE to the network (SMS-SUBMIT).

If/when you find out, feel free to update this answer with regards to that.
