international calling cards?

I have been to Japan many times, but next week will be my first business trip. normally I would use Skype, but Skype changed my number displaying to the receiver.

I heard that calling card is cheapest for international call in Japan. so where can I buy it and what kind? I have to make regular calls to Philippines and Indonesia, fyi.

you can buy a KDDI super world card at the airport or at 7-Eleven

While it is a cheaper than regular call rates, it is much more expensive than Skype.

if you are using smartphone, you should give Global Call app a try. They have prepaid calling cards that are sold in convenient stores and retailers. Plus, there is an on-going promotion of bonus credits and giving away pizza (http://www.globalcallevent.com/pizza_event/pizza_w/en/pizza_w.html).

And the rates are cheapest as well.

Hi, you can use calling cards from www.callingcards.com for all your international calls to Japan. Their call quality is pretty good and I like their rates as well. Good luck!
