Roaming enables a mobile phone in a cellular phone system to receive or to make long distance calls. Such calls are typically more expensive than local calls and therefore most subscribers prefer to minimize long distance calls in order to reduce phone bills. It is therefore desirable for a subscriber to know whether a communication call is long dis- tance or local before starting voice communications.
