title: Sending Twilio SMS from a trial account
body: <p>I am using Twilio and RestSharp packages from nuget to call Twilio using test credentials.  I've verified my personal cell phone already.  I tried using the phone number provided by Twilio as the from number, but I received error <a href="https://www.twilio.com/docs/errors/21606" rel="nofollow noreferrer">21606</a> saying that I couldn't use a live number with test credentials.  The error description provides another number that can be used with test credentials (+15005550006), so I released the live number and switched to using the one provided.</p>
  
  <p>I can now get a successful response from the service, but the status of all messages I send comes back as <code>queued</code>.  The response contains a Uri, but, if I visit the Uri, I get a 403:</p>
  
  <pre><code>&lt;TwilioResponse&gt;
    &lt;RestException&gt;
      &lt;Code&gt;20008&lt;/Code&gt;
      &lt;Message&gt;Resource not accessible with Test Account Credentials&lt;/Message&gt;
      &lt;MoreInfo&gt;https://www.twilio.com/docs/errors/20008&lt;/MoreInfo&gt;
      &lt;Status&gt;403&lt;/Status&gt;
    &lt;/RestException&gt;
  &lt;/TwilioResponse&gt;
  </code></pre>
  
  <p>Tracking through that code tells me that I can't <a href="https://www.twilio.com/docs/api/rest/test-credentials" rel="nofollow noreferrer">connect to real phone numbers</a>.  So, my question is thus:  How do I test the Twilio platform before committing any money to it?  I've seen another question where an answerer has said that <a href="https://stackoverflow.com/a/23850892/128217">trial accounts can send SMS messages to verified numbers</a>, and my Geographic Permissions allow me to send to a +1 number, which the verified number is.  None of the messages I send ever making into my message log.</p>
  
  <p>Any direction would be greatly appreciated.  I'm trying to evaluate this to see if my company should use it, but the trial doesn't seem to be enough to give me any indication of usefulness.</p>
