I got a mobile Wi-Fi router “Hikari Portable” which is provided by NTT East. This product has a battery, a 3G mobile communication unit and a Wi-Fi infrastructure. It sets up a private Wi-Fi network and ties the Wi-Fi network with a 3G data link. Users can access the Internet through the private Wi-Fi network, and 3G data link. The battery enables the Internet access on the go!

NTT East offers Hikari Portable only for rental, not for sale. The rental fee is just 315 JPY per month. It is very low price against sales unit. For SIM free version of Hikari Portable, users can insert a favorite SIM card and make a 3G data link.

I use this unit with EMOBILE 3G services (Japanese site). It costs 4,980 JPY a month (New two-year plan).

The Wi-Fi router is very useful. I can connect the Internet from MacBook, iPhone 3GS, and Android smartphones in the train, cafe, etc.
