Sim800l v2 send message to multiple numbers

Question

I have this data I'm getting through EEPROM "Emergency Contacts: +639*********, +639*********, +639*********;" Using this I want to send a message to these numbers.

I have this function but it only sends to the first number:

void sendSms(String text)
 {
  sim800.print("AT+CMGF=1\r");
  delay(1000);
  String contacts = EMERGENCY_CONTACTS;
  int commaPos;
  boolean allSent = true;
  do {
    commaPos = contacts.indexOf(',');
    String contact;
    if (commaPos != -1) {
      contact = contacts.substring(0, commaPos);
    } else {
      // If no comma found, it's the last contact
      contact = contacts;
    }
    contact.trim();  // Trim leading/trailing spaces
    contacts = contacts.substring(commaPos + 1);
    contacts.trim(); // Trim leading/trailing spaces and update contacts
    sim800.print("AT+CMGS=\"" + contact + "\"\r");
    delay(1000);
    sim800.print(text);
    delay(100);
    sim800.write(0x1A); 
    delay(1000);
    Serial.println("SMS Sent Successfully to " + contact);
    BTSerial.println("SMS Sent Successfully to " + contact);
    if (commaPos == -1) {
      allSent = false;  // Mark that it's the last contact
    }
  } while (commaPos != -1);
  return allSent;
}
