Add them to what? What library are you using to send text messages? Is that library constructed to send to more than one person at a time?

The usual solution is to use a for loop, and send one message, to one person/phone number, at a time.

Hi there ,
I am Using MKRGSM library.
I have written like this
sms.beginSMS(num);
sms.print(txtMsg);
delay(1000);
sms.beginSMS(numb);
sms.print(txtMsg);
sms.endSMS();

But SMS isnot going. I tried

sms.beginSMS(numb);
sms.print(txtMsg);
sms.begin(num);
sms.print(txtMsg);
sms.endSMS();

sms.beginSMS(num);
sms.print(txtMsg);
sms.endSMS();

sms.beginSMS(numb);
sms.print(txtMsg);
sms.endSMS();

sms.beginSMS(num);
sms.print(txtMsg);
sms.endSMS();
delay(2000);
sms.beginSMS(numb);
sms.print(txtMsg);
sms.endSMS();

but proceesor stucks at program. in sms.begin.

I have written like this

Why? Begin sending an SMS. Include some text in the message. Stuff your thumb up your ass for a while. Then, start over sending an SMS. That makes no sense.

but proceesor stucks at program. in sms.begin.

The processor does not "stucks".

Post ALL of your real code, properly indented, in code tags, or all you will get is snippets of answers.

Hi Paul,
I am NewBee!!!
please see the below code. I am not able to send sms to two recipients.

#include "arduino.h"
#include <MKRGSM.h>
#define PINNUMBER ""


#define HIGH 1
#define LOW 0


// initialize the library instance
GSM gsmAccess;
GSM_SMS sms;
int a1 =1;
int  b1 =2;
int c1= 3;
int d1= 4;
int e1= 5;
int f1= 7;
int g1= 8;
int h1= 0;
int a = 0;
int b = 0;
int c =0;
int d = 0;
int e =0;
int f =0;
int g = 0;
int h =0;
int i=0;

void gsm();
void gsm(){
 char *txtMsg;
 char num[11] = {"............."}; //number 1 recipient number//
char numb[11]={".............."}; // number 2 recipient number//
// //
 if(a == false)
 // sms text
{

 
 Serial.print("Now, enter SMS content:1 ");

txtMsg= {"Hi there"};
 
 Serial.println("SENDING");
 Serial.println();
 Serial.println("Message:");
 Serial.println(txtMsg);

 // send the message
 sms.beginSMS(num);
 sms.print(txtMsg);
 delay(1000);
 sms.beginSMS(numb);
 sms.print(txtMsg);
 sms.endSMS();

 
 Serial.println("\nCOMPLETE!\n");
 delay(60000);
 return;
}
}
void setup() { 

 pinMode(a1, INPUT);
 pinMode(b1, INPUT);
 pinMode(c1, INPUT);
 pinMode(d1,INPUT);
 pinMode(e1, INPUT);
 pinMode(f1,INPUT);
 pinMode(g1, INPUT);

 digitalWrite(a1, HIGH);

 digitalWrite(b1, HIGH);
 digitalWrite(e1, HIGH);
 digitalWrite(d1, HIGH);
 digitalWrite(f1, HIGH);
 digitalWrite(g1, HIGH);
 digitalWrite(h1, HIGH);
 // put your setup code here, to run once:
Serial.begin(9600);
 while (!Serial) {
   ; // wait for serial port to connect. Needed for native USB port only
 }

 Serial.println("SMS Messages Sender");

 // connection state
 bool connected = false;

 // Start GSM shield
 // If your SIM has PIN, pass it as a parameter of begin() in quotes
 while (!connected) {
   if (gsmAccess.begin(PINNUMBER) == GSM_READY) {
     connected = true;
   } else {
     Serial.println("Not connected");
     delay(1000);
   }
 }

 Serial.println("GSM initialized");
 
}

void loop() {


a= digitalRead(a1);

b = digitalRead(b1);

c = digitalRead(c1);

d = digitalRead(d1);

e = digitalRead(e1);

f = digitalRead(f1);

g = digitalRead(g1);

h = digitalRead(h1);



gsm();

}
