PROBLEM TO BE SOLVED: To sell a prepaid portable terminal and a prepaid card at a general store, such as a convenience store. SOLUTION: In order to obtain the subscriber's number of the portable terminal 1, first, the purchaser of the terminal 1 and the prepaid card 2 call-originates a request for registering, including a terminal number X with an prescribed access number for requesting registration and a card number M as call-incoming number from the terminal 1. When an exchange 4 receives the request for registering, a prepaid controller 6 confirms the usability of the number M and the presence/absence of a prepaid reminder. After then, an HLR 5 retrieves an unused subscriber's number list to obtain an unused subscriber's number N and registers the positional information of the terminal 1, service information, the number M and the number N in a subscriber information list. After that, the exchange 4 makes the terminal 1 display the obtained number N and informs the terminal 1 of the number N by a voice information device 7. Thereafter, it is possible to call-originate and speak from the terminal 1 and to call-income and speak to the terminal 1 with the number N.
