EMOBILE booth in Yamada
In Yamada and other electronics store in Japan, there is a EMOBILE booth, where you can sign up to EMOBILE on the spot. The second generation EMONE (EMONE α) with cradle costs 39,800yen with subscription (3,480yen-6480yen per month). The flat rate plan is 5980yen .
EMOBILE does not have telephone devices yet, but their HSDPA goes up to 3.6Mbps. They are planning to have telephone service soon, but meanwhile, you can use skype. The pictures in this post were taken with my Advanced W-ZERO 3 [es] in Yamada.
