Rates from Japan

Call other KDDI IP-phone subscribers for free! Uniform rate system for domestic calls as well!

With conventional phone systems, the further away you call, the more you have to pay. But phone calls between IP phone subscribers are free, and uniform rates apply in Japan when calling regular subscriber telephones from IP phones. If you often call people who live far away, this is by far the best plan for you!
