having issue when trying to send sms using jwt token

iam trying to test sms call via code got this error

# POST BODY
body = {
"from": {
"phoneNumber": "+1929415xxxx"
},
"to": [
{
"phoneNumber": "+1929378xxxx"
}
],
"text": "test api call",
}


rcsdk = SDK(RC_CLIENT_ID,RC_CLIENT_SECRET,RC_SERVER_URL)
platform = rcsdk.platform()
try:
# Assuming platform.login() logs in using the token
platform.login(jwt=jwt_token)
# Assuming you have a 'body' variable defined elsewhere
response = platform.post('/restapi/v1.0/account/~/extension/~/sms', body)
data=json.loads(response.text())
print("Request successful.",data)
# Check response status for success
api_response_status = response.json().messageStatus
if api_response_status == "Received" or "Queued":
print('SMS sent successfully!',api_response_status)
else:
print(f'Failed to send SMS. Status: {response.json().messageStatus}')


except Exception as e:
print(f"Error occurred while processing token {e}")
got this error:Error occurred while processing token The requested feature is not available
then tried from api reference ui
got this error
{ "errorCode": "FeatureNotAvailable", "message": "The requested feature is not available", "errors": [ { "errorCode": "MSG-242", "message": "The requested feature is not available" } ] }
