title: How to get the SIM number (ICCID) of a modem using AT commands
body: <p>I'm trying to get the <code>SIM number</code> (<a href="https://en.wikipedia.org/wiki/Subscriber_identity_module#ICCID" rel="nofollow"><code>ICCID</code></a>, not <a href="https://en.wikipedia.org/wiki/International_mobile_subscriber_identity" rel="nofollow"><code>IMSI</code></a>) of my 3G Huawei  E5830 modem using <a href="https://en.wikipedia.org/wiki/Hayes_command_set" rel="nofollow"><code>AT commands</code></a> (also called <code>Hayes command set</code>).</p>
  
  <p>Unfortunately, it's not specified in the modem formal documentation.</p>
