pdu message +079109

I am studying AT commands.
So first I am using hyper terminal.And I connected my cellphone(siemens c55) via data cable.And I read message in my sim card as a PDU mode.But I cant send sms and save message sim card.I dont understand!!!

When I read sms,I am writing that;

at+cmgr=2
079109...
that is right
but when I send sms,it is not true.It gives errror.
How can I write to send sms and save a sms in sim card.,
help me plz
thnks

unsigned char at_cmgr[]= at+cmgr=;

you must first set the memory preference to deal with SMSs.

you can type the command as given below to set your memory preference as "Sim Memory"

AT+CPMS="SM","SM","ME"

SM=Sim Memory
ME=Phone Memory

however, you must verify what commands are supported by Sim memory preferences.


This link below contains a downloadable file for a few of the basic AT commands.

For your Siemens phone, here are some commands.

Re: help about AT commands

you can read this book
( AT+CMGS=<length><cr>)

your PDU has length, when you are using AT Command in the PDU format the length has to be set first.
and remember your cell phone has a timer that count your time when you type your message, when the time is up and you haven't finished your message that would be an error.
and the last thing you should know is, end your message using ctrl+z.

hope it useful.....
