yes, it is possile
you have to make level shifting cable between the phone and your PIC or PC
then you have to search in Google (or your favorite search engine) for
"nokia gsm at commands"
Nokia have very nice AT commands book made as windows help file
then all you need is to find your local sms center dial number (some phones
show this number somewhere in your settings) and to start playing with the
sms at commands
