Answer 1

To complete @Android Fanatic answer

If the text is too long, the message does not go away, you have to respect max length depending of encoding.

More information can be found here.

I'd prefer this method

SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(message);

ArrayList<PendingIntent> sendList = new ArrayList<>();
sendList.add(sentPI);

ArrayList<PendingIntent> deliverList = new ArrayList<>();
deliverList.add(deliveredPI);

sms.sendMultipartTextMessage(phoneNumber, null, parts, sendList, deliverList);

Answer 2

Also SMS Manager doesn't sent messages if the message is longer than 160 for English text, and 70 for 16-bit alphabet text. Try sending small English text to see if it's the case. (You can sent multiple part messages to send long texts).

Use following code to send sms Message, here the error will be shown in Toast

--sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{        
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS sent", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    Toast.makeText(getBaseContext(), "Null PDU", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", 
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(SENT));

    //---when the SMS has been delivered---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;                        
            }
        }
    }, new IntentFilter(DELIVERED));        

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);        
}

Answer 4

String incomming = "9876543210";
android.telephony.SmsManager sms=android.telephony.SmsManager.getDefault();
sms.sendTextMessage(incomming, null,"Here Is Sms", null, null);

Answer 5

Log.d("SMS ready to send", "----FIRST CALL----");
String number = "111111111111"; //ed1.getText().toString();
String message =  "Test SMS DATA"; //ed2.getText().toString();

Log.d("SMS ready to send", "----SECOND CALL----"+number);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(number, null, message, null, null);

Log.d("SMS ready to send", "----THIRD CALL----");
