Wireless telephone communications are processed by first contacting a worldwide wireless access facility which interfaces between the caller and the phone systems to determine a present location of a subscriber. The facility queries the home system requesting a roaming status and number of the subscriber. If the subscriber is roaming, the home network identifies a present serving network for the indicated subscriber from a list maintained of each subscriber's roaming location. The home network queries the present serving system and obtains a temporary local directory number for the subscriber. The home network returns a number to the worldwide wireless facility for reaching the subscriber. The facility uses this number to direct the telephone call to the called party.
