In a telephone system providing a voice mail service, a subscriber's voice mail follows the subscriber as he moves. In, for example, a satellite mobile telephone system, a subscriber may roam over wide areas. As he does so he registers sequentially with different satellite access nodes. These nodes may be on different continents. When the subscriber registers with a new satellite access node, the contents of his previous voice mailbox are transferred to a new voice mail box at the new satellite access node. The subscriber's home location register record and the visitor location register record, at the new node, are updated with the number of the new voice mailbox, so that new voice mail can be routed to the correct mailbox.
