GSM won't make any call

I has put my number 6011234567 so that my GSM can make call / message to this number, but I did not get any calls and messages from GSM, but in serial monital it say , it has call and send message to my number, btw i has use two different of my sim but still don’t solve my problem, is this due to a problem with my sim? sorry for my bad english



String ph1="6011234567"; //Enter your phone number to call #01
String ph2="6011234567";   //Enter your phone number to call #02
int vibrationPin = 2;
bool flag=false;


void setup() {
Serial.begin(9600);
Serial.print("AT+CMGF=1\r\n"); //Text SMS mode in GSM
pinMode(vibrationPin,INPUT);
digitalWrite(vibrationPin,LOW);
//System Calibration
for(int i=0;i<10;i++)
{
  delay(200);
}
}

void loop(){
  int a=vibration();
  if(a>15000){
    flag=true;   
  }

if (flag) {
  message1();    //Generate the Alert Message First Mobile
  delay(1000);
  message2();   //Generate the Alert Message Second Mobile
  delay(1000); //1 minute delay
  call1();      //Call to First mobile
  delay(1000);
  call2();    
      delay(1000);    //call to Second mobile
     
  }
  flag=false;
 }
void message1()  //Method to send message #01
{
    Serial.print("AT+CMGS=\"");
    Serial.print(ph1);
    Serial.print("\"\r\n");
    delay(2000);
    Serial.print("---ALERT---\n Call Police , Any try to Unlock Door");
    Serial.write(0x1A);
}
void message2()   //Method to send message #02
{
    Serial.print("AT+CMGS=\"");
    Serial.print(ph2);
    Serial.print("\"\r\n");
    delay(2000);
    Serial.print("---ALERT---\n Call Police , Any One Try to Unlock Door ");
    Serial.write(0x1A);
}
void call1()   //Method to get call #01
// Dhaddammm Roboyics //
{
  Serial.print("ATD");
  Serial.print(ph1);
  Serial.print(";\r\n");
  delay(10000);
  Serial.println("ATH");
}
void call2()   //Method to get call #02
{
  Serial.print("ATD");
  Serial.print(ph2);
  Serial.print(";\r\n");
  delay (10000);
  Serial.println("ATH");
}
int vibration(){
  delay(10);
  int vibrationDetection=pulseIn(vibrationPin,HIGH);  //wait for the pin to get HIGH and returns measurement
  return vibrationDetection;
   
}

How is this connected with Blynk?

Pete.

no, i just want this program to make a call / message to my phone only
