The GetAddress method can be used to determine if a phone 
          number is associated with a mobile device and obtain the email 
          address for the wireless service provider's gateway. This is done by 
          sending an query to a server that will check the phone number against 
          a database of known providers and the phone numbers that have been 
          allocated for wireless devices.
          By default, this method will attempt to automatically determine 
          which service provider is associated with the phone number. If the 
          service provider cannot be determined, this method will fail and 
          return an error code. If the Provider property has 
          been set to to the name of a specific service provider, that provider 
          will be used to determine the gateway email address.
          This method sends an HTTP query to the server api.sockettools.com 
          to obtain information about the phone number and wireless service 
          provider. This requires that the local system can establish a standard 
          network connection over port 80. If the client cannot connect to the 
          server, the method will fail and an appropriate error will be 
          returned. The server imposes a limit on the maximum number of 
          connections that can be established and the maximum number of requests 
          that can be issued per minute. If this method is called multiple times 
          over a short period, the control may also force the application to 
          block briefly. Server responses are cached per session, so calling 
          this method multiple times using the same phone number will not 
          increase the request count.
