Are you sending SMS from real device or Emulator? – Abbasid

using Emulator only.. – Gavrilla

You should send message using real device not with Emulator... – Abbasid

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).

Answer 3

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

Answer 4

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----");
