user49013: After few minutes of using Google, I found a library that contains everything you need to send/receive SMS and phone call. Here's the code I made in two minutes. 
Currently I don't have SIM800L module, so I can't test it. Be sure you type a valid number format. For Croatia it's +385 XX XXX XXXX. +385 is an "international dialling code" for Croatia. Don't forget to put + before IDC.
serialSIM800.write("AT+CMGF=1\r"); 
serialSIM800.write("AT+CMGS=\"");
serialSIM800.write("PHONE_NUMBER");           
serialSIM800.write("\"\r");       
serialSIM800.write("Emergency at IIST");
serialSIM800.write("\r0x1A");
