bought it. very good. there's service all the time. I was in osaka and travelled to tokyo by shinkansen. Was surprised that despite going through some 'remote' areas, there was still service. So, u dont have to worry of not getting service.

I off it during my walking period and switch on to it when i need to check on something or to update my social network. All in all, i'll give it a 10/10. Well, i am easily pleased to begin with. No complain from me.
