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.
