BSNL Dlt - "Unknown error attempting to reach phone" / "Phone carrier has blocked this message" - Promotional Messages, Registered SenderID, TemplateID, EntityID - Nodejs

0

So, after following through the aws docs I have completed the process of DLT Registration and have successfully received a Certificate (BSNL Dlt) with the EntityID.

Now in the DLT console I have created the SenderID and TemplateID as well (both were approved by the DLT) and am using the same to send an SMS to my users.

I raised a case with AWS also to register my SenderID and I do see the same has been approved and AWS Pinpoint SMS reflects this

Following is the Code that I am using :

async publishToPhone(phoneNumber, message) {

    var params = {
      PhoneNumber: phoneNumber,
      MessageStructure: 'string',
      Message: message,
      MessageAttributes: {
        "AWS.SNS.SMS.SenderID": {
            DataType: 'String', StringValue: 'TNPNWS'
        },
        "AWS.SNS.SMS.SMSType": {
            DataType: 'String', StringValue: 'Promotional'
        },
        "AWS.MM.SMS.EntityId": {
            DataType: 'String', StringValue: '1401599xxxxxx65494'
        },
        "AWS.MM.SMS.TemplateId": {
            DataType: 'String', StringValue: '1407170xxxxx49047'
        }
    }
    };
    
    const data = await sns.send(new PublishCommand(params));

    if (!data) {
      throw Error(`There was an error in publishing ${params.Message}`);
    }

    return data;
  }
  • Have you registered the SenderId with India? It is next to impossible to get an approval for local routes in India unless you are an Indian company.

Which country are you sending the message to? Some countries don't support senderID. See the list here.

  • India - I did all the steps required to get the SenderID. Unfortunately it still happens.

  • Also AWS has approved the SenderID
