       foreach($new_tokenss as $new_token)
    
            {
        
$message = "Message";
        $message_encoded = urlencode($message);
        $postData = array(
            'authkey' => \Config::get('procedures.msg91.authKey'),
            'mobiles' => $new_token->mob,
            'message' => $message_encoded,
