StringEntity entity = null;
 //For sending SMS using POST method requires whole message to be in xml string format. It has all the parameters that are in get only in xml format.

          String inputXML= "<message><submit><da><number>9780.....</number></da><oa><number>Test Sender</number></oa><ud>Hello +esting</ud><from><username>abc</username><password>xyz</password></from><to>send</to></submit></message>";

// While using HTTP POST you have to set content type to "text/xml" or else it wont work
              InputStream in ;
                  entity = new StringEntity(inputXML, ContentType.create("text/xml", Consts.UTF_8));
                 entity.setChunked(true);
