Twilio - Number Lookup -

i trying lookup carrier of phone number using twilio php sdk. however, getting certification error. not sure doing wrong. if can give me advice, appreciate! thank you.

$lookup_client = new lookups_services_twilio( $this->twilio_sid, $this->twilio_token );  $number = $lookup_client->phone_numbers->get(             '1-416-333-1111',             array(                 'type'          => 'carrier',                 "countrycode"   => "us",             ) ); echo $number->carrier;
