Code is similar to the SMS manager example .

Answer 1

Could you write your code?

This code works for me:

   private void sendSMS(String phoneNumber, String message)
   {
       SmsManager sms = SmsManager.getDefault();
       sms.sendTextMessage(phoneNumber, null, message, null, null);
    }

And in the manifest:

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

Answer 2

Use such thing to send sms...

 //---sends an SMS message to another device---
@SuppressWarnings("deprecation")
private void sendSMS(String phoneNumber, String message)
{        
    Log.v("phoneNumber",phoneNumber);
    Log.v("MEssage",message);
 //   PendingIntent pi = PendingIntent.getActivity(this, 0,
 //       new Intent(this, Main.class), 0);                
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);        
}   

To call it just ...

sendSMS("+4956421246", "test");

Answer 3

Try This

public void send_sms(String Docket_no,String mob_no)
{
    String phoneNo = mob_no;
    String sms = "Docket succesfully added.  Docket No :" + Docket_no;


    try {
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(phoneNo, null, sms, null, 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();
    }   
}
