DoCoMo, J-Phone, KDDI: Keitai Catalogs Tell All
I picked up the November cell phone catalogs from several carriers the other day, including DoCoMo (for 3G FOMA), KDDI, and Tu-ka, as well as the J-Sky service catalog from J-Phone. You really needn’t look much further than these monthly catalogs if you want a concise, full-color, and neatly packaged window into the marketing plans and keitai sales hopes of the major Japanese carriers. Depending on which handset you have, you can now access data networks at 9.6, 28.8, 64, or 384 Kbps – and many devices can access two networks. Note that 64 Kbps data is available via FOMA (the 3G network) and via PHS (not formally called “2G” but certainly not 3G). Finally, there’s the Mzone WLAN service that operates at hotspots inside the Yamanote line and at a few other locations.

This week, we finish up our Killer Interview Series and find out how NTT DoCoMo is handling spam, a serious quality-of-service issue. Why don’t the other carriers have similar spam problems? Maybe they’re just not telling…
In the first part of our Killer Interview Series with one of Tokyo’s contrarian telecoms analysts, we find out what happens to data ARPU when price-insensitive, heavy-volume users migrate to new services (like Java). The answer? It’s not a pretty sight, and the same may be in store for 3G. Plus, we cover ARPU stats, compare FOMA data usage to 2G, and reveal what generates the most packet traffic (think “self-generated content”).
This week, Wireless Watch Japan sits down for coffee with Drew Freyman, Tokyo pointman for Nokia Venture Partners, a VC fund targeting the wireless space. We ask “Can Japanese wireless service providers follow DoCoMo overseas?”
