    // ---sends an SMS message to another device---
    public static void sendSMS(String phoneNumber, String message) {

        PendingIntent piSent = PendingIntent.getBroadcast(mContext, 0, new Intent(SENT), 0);
        PendingIntent piDelivered = PendingIntent.getBroadcast(mContext, 0,new Intent(DELIVERED), 0);
        SmsManager smsManager = SmsManager.getDefault();

        int length = message.length();
