Well this link takes you to the voice plan pages.

Let's set aside the fact that it may prove difficult for someone lot living in Japan to "sign-up" for one of these plans.

Even at the lowest monthly rate, you're still paying a minimum of 3500/month. That's means over 40,000 in prepaid phone time if you have a prepaid handset. At 100 yen/minute for both domestic and international calls via prepaid vs 40~50 yen per minute on the cheaper rate plans on post pay?

The break even point on this (assuming that minutes do not roll over) has got to be in the neighborhood of 800~1000 outgoing minutes per year from Japan if you factor the cheap intl calling and free incoming minutes.

But getting back on topic...

Can anyone point to evidence that it is possible to get Japanese USIM/SIM that when inserted into a 3G handset will allow local calling in Japan at less than the 100 yen/minute.

I'm not trying to pick a fight here. I merely adopted the role of "Devil's Advocate"

Cheers,
