How to enable A2PSmsSender feature for my extension

As you wrote that you have submitted the form and it got approved, I assume that it is the TCR registration form. That process does not include high volume SMS provision. Please use this form to submit your request HV SMS provisioning for those numbers.

Thanks for your response. We did submited 2 time for 2 number as bellow:

+16573346195 & +14088774000

The problem is that we are using JAVA JDK to send out the text but alway got the error

"errorCode":"CMN-101","message":"Parameter [from] value is invalid.

Im checked out and 2 above number don't have the feature "A2PSmsSender" we contact dev team but there are no update from the team.

Can you please help me to check it out?

This happened on both of numbers: (657)XXX6195 and (408) XXX-4000

This is my code
    CreateSMSMessageBatchRequest parameters = new CreateSMSMessageBatchRequest();
    parameters.from = RC_USERNAME;
    parameters.text = "Hello Team, This is HV SMS";
    String[] numbers = new String[] {RECIPIENT_NUMBER, "+14243325470"};
    parameters.messages = new MessageCreateRequest[numbers.length];
    for (int i=0; i<numbers.length; i++) {
      MessageCreateRequest m = new MessageCreateRequest();
      m.to = new String[] {numbers[i]};
      parameters.messages[i] = m;
    }

Im using ringcentra-java v2.4 here https://github.com/ringcentral/ringcentral-java">https://github.com/ringcentral/ringcentral-java

Can you help me to check it out? I did find aground but could not find any solution for this.

I check your numbers and found that they are not provisioned for HV SMS. You can double check using the API to read the number features.

public void read_extension_phone_number() throws RestException, IOException{
      var resp =  restClient.restapi().account().extension().phonenumber().get();
      for (var record : resp.records) {
            for(var feature : record.features)
            {
              if (feature.equalsIgnoreCase("A2PSmsSender"))
              {
                // this number is a HV SMS number.
              }
            }
        }
    }

Then you have to send a request for HV SMS provisioning. Make sure that your TCR registration is for HV SMS as I wrote earlier.
