hi fist of all are you using the simulated second put the send sms in a try catch

      try
            {
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(PhoneNumber, null, SmsContent, null, null);
  Toast.makeText(getApplicationContext(),"wow",Toast.LENGTH_LONG).show();

            }
            catch(Exception e)
            {
                 Toast.makeText(getApplicationContext(), e.printStackTrace,Toast.LENGTH_LONG).show();
            }

if it is a try catch the app wont crash
