The point is that all the transport layer protocol have port numbers. So, if you have a stable IP address and, say, 256 stable port numbers, your mobile device running applications as a server, can be reached by the port number, distinguished from other mobile devices sharing the IP address. Such a service might cost $10 a month or Gree might offer it free of charge. Masataka Ohta
