## Send SMS
```js
  hilink
    .sms('Hello!', '500600700')
    .then(() => { console.log('success!'); })
    .catch((e) => { console.log('fail!', e); })
```
or use async/await
```js
  try {
    await hilink.sms('Hello!', '500600700');
    console.log('success!');
  } catch (e) {
     console.log('fail!', e);
  }
```

[typescript]

`async sms(message: string, recipient: string | string[]): Promise<void>`

parameter | Description | type
--- | --- | ---
`message` | SMS text | String
`recipient` | phone number / numbers | String / Array of Strings


## Destroy instance
It is important to release resources and avoid memory leaks!
Internal implementation of SMS queue is based on timer - remember to clear it as soon as you stop using `hilink-nodejs-sms` functionality.
```js
  hilink.destroy(); // IMPORTANT! remember to release resources!
```
After `destroy` method is called, sending SMS is no longer possible.
