Every country or regional data plan you purchase for holiday.com’s eSIM is only valid for a specified area for an indicated period of time. Let’s say you’ve purchased a 7-day data plan for the U.S., which activates automatically upon arrival in the country. While your U.S. data plan is still active, you travel to Canada instead. Your U.S. data plan will not have its data used while you’re away, but will still expire after the 7-day period regardless of how much data was unused.
