body: <p>how can i determine if network type is 2g, 3g or 4g using xamarin essential </p>
  
  <p>I know xamarin essential  has functions to identify connectivity type</p>
  
  <pre><code>var current = Connectivity.NetworkAccess;
  
  if (current == NetworkAccess.Internet)
  {
       // Connection to internet is available
  }
  </code></pre>
  
  <p>But if it is internet type then i want to know if it is 2g/3g/4g/5g</p>
