The main source is GSM 03.40. You can download this free (after
registering) from
www.etsi.org. Go to "Get a Standard", "Download Now !", and
search for "03.40". Pick a recent version from the unsorted
list.
You'd be advised to grab GSM 07.05, 07.07 and 03.38 while you're
there. GSM 07.05 will tell you about text-mode and PDU-mode
(your phone might not support both), and the "AT+CMGF" command
used to switch modes. You can setup the header in either mode,
but the mechanism is different.
If you settle for PDU-mode, the Siemens Internet PDF publication
"Developer's Guide: SMS with the SMS PDU-mode" has a lot of
clear, relevant information in the one place. I don't have a
direct URL for it any more - let me know if you want a copy
(despam my address).
