How to use KDDI phonecard

I just bought a KDDI SUPER World card and I have tried many times call from Green phonebooths with no luck.

I have followed the instructions written at the back side of the card.

Just dialed 0055+CARD_NUMBER+COUNTRY_CODE+AREA_CODE+PHONENUMBER#

Thats what I did, but didnt manage to reach destination.

Am i doing something wrong.. i dont have japanese operator with me.

What to do?

Tsuiya,

Did you remember to leave off the "0" on the area code?

Make sure the green phones can make international calls, try the grey ones instead.

Also as mentioned when dialing the country code, leave out the 0

You have to wait for the prompt after dialing 0055.

With the green phones, you'll need to insert a 10yen / 100yen coin or Telephone Card with at least 1 unit credit to get a dial tone to dial 0055 (which is a free call).

One thing I do find confusing with that card is when you enter 0055 it then asks you to enter a credit card number then press start. At that point you just enter all the information. But I can imagine how many people that confused (including myself) before.

Also I don't think you need to enter the "#" pound button, though I'm sure sometimes people enter it because it appears on the card as well.
