I connect arduino with sony ericsson k700 and I make the sketch.....

char incomingByte;
void setup(){
  delay(10000);
  Serial.begin(9600);
  delay(3000);
  Serial.println("AT+CPMS=\"ME\",\"SM\"");//select phone memory
  delay(6000);
  //Serial.println("AT+CMGF=1");//text mode
  delay(6000);
  Serial.println("AT+CMGR=1");//read sms
  //Serial.println("AT+CMGD=1");//delete sms
  delay(6000);
}
void loop(){
  delay(3000);
  if (Serial.available()>0){
    incomingByte=Serial.read(),BYTE;
    Serial.println(incomingByte);
    
  }
}

I have problem no display the insert text message only phone number of sender and time,date...is pdu format.
