hardware interrupt for new sms

I am using sim300CZ gsm module and pic16f877 for my project.

Is it possible to make any hardware interrupt when any new sms arrived??

thanks in advanced

have a look at Darryl's asembler interup handler i used it with sucsess in my project with a siemens GSM module, picBasic's interups are to slow
