Sorry for the confusion. Let me clarify unlimited in the context of this conversation.
Unlimited means no data cap or throttling when certain limits are exceeded. Truly in every interpretation, Unlimited.
In this case the NTT mentioned before cannot be considered for the same reasons I do not consider my Softbank service to be unlimited as I am limited by two conditions:
1. 1 gig in 3 days initiates a throttle. No way out until it expires.
2. 7 gig in 1 month initiates a throttle, which you can selectively pay your way out of.
I hit the (1.) condition quite a bit, it's annoying.
thanks,
RDP
