Clickatell showing Delivered to gateway but SMS is not received using Java?

Question

I am using clickatell sms gateway to send SMS to the User in Java.

For that I have registered on clickatell and purchased Small Business API - Americas Regional Traffic to send sms to USA users. I have activated Two-Way Number . My Java code is looks like -

    String url = "http://api.clickatell.com/http/sendmsg?";
    List<NameValuePair> params = new LinkedList<NameValuePair>();
    params.add(new BasicNameValuePair("user", "user"));
    params.add(new BasicNameValuePair("password", "password"));
    params.add(new BasicNameValuePair("api_id", "XXXXX"));
    params.add(new BasicNameValuePair("to", "1XXXXXXXXXX"));
    params.add(new BasicNameValuePair("text", "Demo Message"));
    params.add(new BasicNameValuePair("from", "my-two-way-number"));
    params.add(new BasicNameValuePair("mo", "1"));

    String paramString = URLEncodedUtils.format(params, "utf-8");
    url += paramString;
    HttpGet get = new HttpGet(url);

    HttpResponse response = client.execute(get);

When I run this java code I get the api-message-id in response, I have checked the status of the this api-message-id on clickatell message report it shows Delivered to gateway, but the message was received on the Phone.

The phone number format I'm using is 1 for country code and rest 10 digits of phone number. When I try with other format it gives me error.

I am not understanding why I am not receiving SMS on my phone while it is showing Delivered to gateway

Answer 1

If you have sent the sms to an Indian number:

As per TRAI regulations, you are only permitted to deliver promotional or commercial messages during normal office hours. Please refer to the following page for the full regulations

http://www.nccptrai.gov.in/nccpregistry/regulation1diccndiv.pdf.

Please refrain from sending messages after 9pm India local time.

I have contacted the customer care and came to know this information.

"Delivered to gateway" means Clickatell has handed it off to the gateway provider, and that the gateway provider will then try to deliver it to your handset. As soon as that has happened, the status will change to "Delivered to handset" or "Received by recipient" or someething similar.
