Нужны рабочие смс для chikka api в PHP

Всем добрый день! специально для тех, кто является экспертом в chikka sms api

У меня проблема, которая заняла у меня 3 часа, но все равно не повезло...

Я решил выбрать chikka как мой sms api в нашем проекте capstone...

это код, который я загрузил в GitHUB, и пользователь здесь, в stackoverflow (Maverick), также добавил, что поток его конфигурации работает, но мой не...

это код:

example.php

<?php
/**
 * This file will show a simple implementation on how to send SMS using Chikka API

include('ChikkaSMS.php');

$clientId = 'b43964ce5433fecdc4ee6fd7717xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$secretKey = '49502a1819b22c8465d5d6783d2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$shortCode = '29290xxxxxx';
$chikkaAPI = new ChikkaSMS($clientId,$secretKey,$shortCode);
$response = $chikkaAPI->sendText('1234561', '63906xxxxxxx', 'tests');

header("HTTP/1.1 " . $response->status . " " . $response->message);

exit($response->$description);
