"TeleChoice" is the service of giving a discount on the total toll charge for all calls dialed to pre-selected toll numbers every month, regardless of the day of the week and time of day each of the calls is made, in exchange of levying a fixed, monthly extra charge for the service. There are two service options: "TeleChoice 10" and "TeleChoice 15". TeleChoice 10 levies a fixed monthly charge of 100 yen and allows a 10 percent discount on the total charge on all toll calls made to two selected toll numbers each month if the total toll charge in that month exceeds 1,000 yen. TeleChoice 15 levies a fixed monthly charge of 200 yen and allows a 15 percent discount on the total charge on all toll calls made to five selected toll numbers each month if the total toll charge in that month exceeds 1,330 yen.
