Hi. I many years work with gsm application. SIM300 have choise how to use . On first is possible receive data from gsm module with no request. If incoming call, receive sms, change any status... and more . then gsm module send specific at command and inform user so are some interupt (but not all at command support). other solution is , disable all SERVICES NOTIFICATION with AT+CSSN=0,0. and every some time send request to gsm module and then gsm module answer. my eanglish is very poor and I don't good wrtie answer for your question.
