Better Exception Handling (script breaks if one number is wrong)

When am sending an sms to multiple users if one of the phone numbers has an issue Twilio throw an exception and the rest of my code is not executed. after digging into the code i discovered that there is need to catch the exceptions and pass them on watchdog so that the rest of the script can continue running here is the modification to the code

  case '2010-04-01':
      // Include the PHP TwilioRest library
      require_once DRUPAL_ROOT . '/' . $config['sms_twilio_path'] . '/Services/Twilio.php';
      $client = new Services_Twilio($AccountSid, $AuthToken);

      switch ($command) {
        case 'sendmsg':
          try {
            $response = $client->account->messages->create(array(
              "From" => $twilio_number,
              "To" => $data['number'],
              "Body" => $data['message'],
            ));
          }
          catch (Services_Twilio_RestException $e) {
             watchdog('sms_twilio', $e->getMessage());
          }
        break;
      }
