      <h1>SMS Component PHP USSD Sample</h1>
      <hr />
      <p>
        USSD stands for Unstructured Supplementary Services Data. It is a way of sending
        short commands from the mobile phone to the GSM network. It uses, like SMS, the
        signalling channel of the GSM connection. Unlike SMS, it does not use a store
        and forward architecture, but a session oriented connection. USSD text messages
        can be up to 182 bytes in length. Messages received on the mobile phone are not
        stored.
