Unexpected character encountered while parsing JSON string
<p>Any idea what could be wrong with this JSON string? </p>

<pre><code>"\"iccid\":\"8500000000000000005\",\"msisdn\":\"4485000000005\",\"comment\":null,\"lastSessionStart\":1480120318000,\"lastSessionEnd\":1480120456000,\"simStatus\":\"Live\",\"activated\":true,\"enabled\":true,\"connected\":false,\"usage\":73728}"
</code></pre>

<p>I tried unescaping it by:</p>

<pre><code>json = json.Replace("\\\"", ""); 
</code></pre>

<p>but I'm still getting this error:</p>

<blockquote>
  <p>Unexpected character encountered while parsing value: 1. Path
  'lastSessionStart', line 1, position 91.</p>
</blockquote>

<p>JSONLint.com says it's a valid JSON format.</p>
