Have you used 15GB international pass?

    If so, please note

    They advertise “The new 15GB International Pass includes 15GB of high-speed data to be used up to 30 days for just $50.”  I would think most people would think that “up to 30 days” would mean the earlier of 30 days or when you reached 15GB of data, not the earlier of 30 days or when you reached the end of your billing cycle. Maybe you should say at the end “or at the end of your billing cycle, whichever comes first”.
