SMSManager not working on Samsung Galaxy S3 LTE

Question

I created simple code to send SMS which is working on Xperia U and QMobile (local brand). But it is not working on Samsung Galaxy S3 LTE

They code is

import android.telephony.SmsManager;
SmsManager sms = SmsManager.getDefault();
            PendingIntent sentPI;
            String SENT = "SMS_SENT";

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

            sms.sendTextMessage("01234567890", null, msg, sentPI, null);

Answer 1

first be sure to add the permission to send SMSs

<uses-permission android:name="android.permission.SEND_SMS" />

and then surround your code with try and catch to find the error that prevents sending in Samsung s3 lte ..

      try {
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage("01234567890", null, msg, sentPI, null);
        Toast.makeText(getApplicationContext(), "SMS Sent!",
                    Toast.LENGTH_LONG).show();
      } catch (Exception e) {
        Toast.makeText(getApplicationContext(),
            "SMS faild, please try again later!",
            Toast.LENGTH_LONG).show();
        e.printStackTrace();
      }
