Microcontroller › PIC › reading sms from gsm modem and comparing with predefind one › you need a level converter

you need a level converter between PIC & GSM modem because the GSM modem has a level converter inside which converts ttl to rs232 level, so you should not connect GSM modem directly to controller, you got to use level converter to convert these rs232 levels to ttl levels again.
