title: Does T-Mobile network allow incoming UDP packets?
body: <p>Short version: <strong>Does the T-Mobile network allow incoming UDP packets?</strong></p>
  
  <p>Longer version:</p>
  
  <p>I'm writing a small test app that connects two Androids over a mobile network. It works over LAN but not over 3g.</p>
  
  <p>Most carriers block incoming TCP connections over their networks, Does the same restriction apply to incoming UDP?</p>
