Peak hours are M-F, 5:59am - 9:01pm - everything else is considered "off peak". So evenings from 9:01pm - 5:59am, and weekends, Friday from 9:01pm till Monday at 5:59am are all "off-peak".
Do those times apply to the local timezone where the phone currently is, or the billing/home time zone?
The local time zone the phone is physically located.
