I plan to use the $35, 10-day, 5GB International Pass while traveling overseas.
How are the 10 days calculated? If I set the plan to begin on Nov. 1, what, exactly, does that mean? Will the plan start at a second past midnight on the morning of Nov. 1 and end at a second before midnight on the night of Nov. 10, and, if so, in which time zone? Does it start/stop at midnight in my home time zone (U.S. Eastern), in another U.S. time zone, or in the time zone of my first destination, which is many hours ahead of the U.S.? Or does it start when I actually start using it?
