Your CheapESIM plan for Hong Kong activates only when you connect to a local network upon arrival. You can complete the installation steps at home before your trip, perhaps while packing. The validity period, whether it's 7 days or 30 days, begins the moment your device registers with a network in Hong Kong, not when you purchase or install the eSIM. This means you get the full duration of data service precisely when you need it, maximizing your value and ensuring no days are wasted before you even land.
