What happen, If the TEL0051 reveive a SMS while GPS mode is enable

Good after noom.

I looking at this code
How to drive the GPS Mode via Arduino board
https://www.dfrobot.com/wiki/index.php/G ... uino_board
If you look carefully, you at the setup loop, you can see this 
First GSM is enable and GPS.

Code: Select allvoid setup() {  pinMode(3,OUTPUT);//The default digital driver pins for the GSM and GPS mode  pinMode(4,OUTPUT);  pinMode(5,OUTPUT);  digitalWrite(5,HIGH);  delay(1500);  digitalWrite(5,LOW);  digitalWrite(3,LOW);//Enable GSM mode  digitalWrite(4,HIGH);//Disable GPS mode  delay(2000);  Serial.begin(9600);  delay(5000);//GPS ready  Serial.println("AT");    delay(2000);  //turn on GPS power supply  Serial.println("AT+CGPSPWR=1");  delay(1000);  //reset GPS in autonomy mode  Serial.println("AT+CGPSRST=1");  delay(1000);  digitalWrite(4,LOW);//Enable GPS mode  digitalWrite(3,HIGH);//Disable GSM mode  delay(2000);  Serial.println("$GPGGA statement information: "); }

I know it's an exemple, but what happen if the GPS mode

Code: Select all  digitalWrite(4,LOW);//Enable GPS mode  digitalWrite(3,HIGH);//Disable GSM mode  delay(2000);

is enabled for 1mn and an incoming SMS is receiving?

The TEL0051, can receive call or SMS with GPS mode is enable?

Many thnak for your explication
Cheers
