It turned out that several partners have already started to offer international call services at a per-minute rate of less than 5 yen to several major countries.

Thus domestic access can be supplied at a fixed rate which enables the flat –rate international IP telephone business.
Besides, Rakuten mobile offered by Fusion Communications is also a service equipped with W-VPN system. Fusion Communications connects its network with that of WILLCOM’s directly as well and provides service with the merit of two networks.
